STALLION SAHARA tire management solution has been specifically developed to comply with the following criteria:

SAHARA extends tire life and saves money.
By eliminating air pressure loss, your tires will always be operating at the correct pre-set pressure. By operating at the correct pressure, tread wear and casing fatigue can be reduced, which means you will enjoy longer tread life, more retreads per casing and use less fuel.

SAHARA retains the air volume/pressure in all tires.
It is normal for tires to lose small amounts of air during normal operation aka porosity. This doesn’t mean the tire is faulty or damaged, but it does require regular pressure checks. When you have Sahara installed, air loss no longer occurs. Sahara will prevent air loss and stop bead/rim/vent and o-ring leaks. For safety reasons it is still recommended to check tire pressure in accordance with federal, state and provincial laws.

SAHARA reduces rolling resistance, therefore increasing fuel economy.
Have you ever tried pushing a vehicle with a flat or partially flat tire? Even 5% under-inflation will increase the tires rolling resistance, which in turn requires more energy (fuel) to move the tire along the road. By retaining the correct air pressure, rolling resistance is reduced, resulting in less friction and fuel used.

SAHARA reduces costly down time.
Lost productivity is expensive and frustrating. A common cause of downtime is usually a tire related problem. By considerably reducing tire-related problems, your downtime will be reduced and productivity/profits increased.

SAHARA coats the inner liner of tires to permanently eliminate air loss due to porosity and bead/rim leaks for the life of the tire tread.
Due to its advanced technological formula, Sahara forms an even thin protective coating over the inner liner of your tires, which permanently seals against porosity and bead/rim leaks.

SAHARA helps prevent belt and tread separation in the tire.
The major cause of belt and/or tread separation is overheating of the tire due to under-inflation and/or overloading. Sahara will ensure the tire is at correct pressure at all times, thereby maintaining the correct operating temperature of the tire. Sahara also acts as a heat transfer agent, helping to reduce the operating temperature of tires.

SAHARA moisturizes the tire casing and prevents it from drying out.
Just like our skin; tire’s dry out with age and chamber heat. By moisturizing the casing, you can extend casing life and even obtain more recaps per casing.

SAHARA increases the number of recaps per casing.
The number of recaps per casing is largely dependent on the condition of the casing. The main factor that has a negative effect on casings is under-inflation, which causes excessive flexing and overheats the tire. By eliminating air loss with Sahara, the under inflation/overheating factor is eliminated, resulting in longer casing life and more recaps per casing.

SAHARA is quickly and easily wiped or washed out of the casing with water.
Sahara has the unique ability to coat the inner liner of a tire without permanently bonding to it. This enables Sahara to be easily removed from a dismounted tire for recapping or to carry out a section repair or damage too large for Sahara to seal.

SAHARA permanently seals average size punctures in the tread area of the tire.
We would like to be more specific when describing the size of punctures Sahara will seal. In controlled testing situations, Sahara has sealed punctures larger than ½” or 12mm. In real life situations, however, certain variables will determine the size of puncture that can be sealed, variables such as: tire dry rot, condition of the tire, shape of the puncturing object, location of puncture in the tire. (Because of safety and excessive flexing, Sahara will not seal punctures in the sidewall area). If sidewall damage occurs, it is recommended that you contact your tire shop for professional evaluation.

SAHARA does not harm steel or aluminum rims.
Sahara contains high performance superior rust inhibitors against ferrous and non-ferrous metals and is compatible with both steel and aluminum rims.

SAHARA protects steel belts from rust and corrosion.
Sahara seals the puncture and will protect steel belts from rust and corrosion.

Sahara provides all weather protection.
Sahara offers considerable protection against both extreme heat and extreme cold conditions. Laboratory tests conclude that Sahara has a freezing point of – 50 degrees C (-58 degrees F) and a boiling point of 188 degrees C (370 degrees F).

Sahara is “environmentally” friendly.
Sahara has been formulated to ensure it’s harmless to our environment. All ingredients used in Sahara are non-toxic, biodegradable and environmentally friendly.

Sahara is “non toxic” and harmless to skin etc.
Sahara’s proprietary formulation consists of ingredients that are used in food, pharmaceutical and cosmetic applications.

Sahara is compatible with the materials used in all tires and rims.
Unlike some tire sealants; Sahara does not react against any components used in the production of tires and rims.

Sahara is used as a tire/wheel end balancer based on dynamic balance media.
Trucking companies usually neglect to balance their drive and trailer tire/wheels and those who do balance their tire/wheels have to frequently.

Balancing is costly almost $35 to $45 per tire. Sahara is designed to act as a tire/wheel end balancer and acts far superior then traditional metal weights, powder balancing, glass beads, disc balancers or liquid balancers.

With the dynamic balance system, you add Sahara inside the tire. The physics statement for this process is: a free floating mass in a spinning assembly will seek equilibrium. In other words, it self balances. As an overall concept this system re-balances the assembly each time you accelerate from a stop.

Preferences aside, in tests we have conducted, if the other tire wear factors have been handled, balance improves tire life on trucks and buses between 10 and 20% compared to no balance. Just remember, balance by itself will not stop all cupping. There are other factors at play in the tire that need to be considered as well.

Sahara has been tested by ARDL.
ARDL, one of the most recognized labs in the world for tire/rubber testing. The test was based on OEM test standards and TMC RP.

ARDL test – EXECUTIVE SUMMARY:

It clearly shows and proves that the tire with Sahara will run cooler and if compared to tires run in the real world without Sahara the temperature difference witnessed has been as high as 20%. Tire temperatures varies on speed, elevation, ambient temperature and load and therefore every fleet depending on these factors will vary in the percentage.

Sahara will not cause chamber fires in a retread plant.

Chamber Test (Test # PN94504)

  • Stallion products do not support combustion.
  • GC/MC Test (ENTNB5-24-1)

Stallion products do not support combustion and will not cause a fire in the retread chamber.

“One of the major concerns to everyone who retreads tires is the quality of the casing and the ability for the casing to undergo standard inspection procedures. The decision to accept a tire for retreading is the decision to put a company’s name on the final product. We tested Sahara in one of our trucks for a period of four months and during the inspection stage we noticed it had sealed two nail punctures. Sahara will not cause chamber fires; it easily washes out and has passed our retread process.”

Preventative maintenance has become standard procedure for equipment owners/operators and fleets. However, the lifeline between your equipment and road surface are your tires. Tires are the second most costly component in your fleet.

The most critical factor in tire maintenance is correct inflation and no tire is completely impervious to pressure loss. Driving on an underinflated tire will not only cost more, it is an extremely dangerous situation with possible life threatening implications. Sahara works proactively to prevent air loss, thereby providing significant cost savings for commercial and industrial fleet operators.
 

Commonly Asked Questions About Sahara

 
Q. How often should I put Sahara in a tire?
A. Sahara is a once only application that lasts for the legal tread life of the tire.

Q. How is Sahara Installed?
A.Installation is fast and easy. Sahara is installed directly into the tire trough the valve stem (core out) with an optional hand pump or it can be pumped or poured with a measuring jug into the tire before the tire bead is seated to the rim flange.

Q. Is there a higher absorption rate in retread or used tires requiring more product?
A. Yes. Depending on the retread casing grade it may require 10% more product. Used tires (30-40% worn) may require approximately 10% more product.

Q. Will Sahara affect retreading of my casings?
A. No. You can expect more retreads per casing. Sahara reduces the operating temperature of tires and moisturizes the casing preventing them from drying out. Your casings will last longer. Sahara will also prevent heat and oxidation damage to the casing liner.

Q. Will Sahara affect the retread process?
A. No. Sahara has been tested and passed all retread manufacturers’ process. Puncture holes sealed with Sahara were found with both visual and nondestructive inspection (NDI).

Q. Does Sahara affect the tire manufacture’s warranty?
A. No. Sahara does not affect the tire manufacture’s warranty. In fact, Sahara has passed ARDL’s tire engineers test criteria. ARDL is one of the most recognized labs in the world for tire/rubber testing. The test was based on OEM test standards and TMC RP.

Tire manufacturer warranties specifically state that “unless the introduced product damages the tire” it will not affect their warranty. There are no ingredients or chemicals in Sahara that are detrimental to materials used in the manufacture of tires. Sahara’s non-toxic and biodegradable properties do not react against any components used in the production of tires/rims.

Q. Can Sahara be used in type tube tires?
A. Yes. The principal is the same as with tubeless tires. Once Sahara is injected into a tube (Note: Sahara can be injected inside tubes any time. Tubes do not have to be in the tire). It will coat the inner tube surface but the coating to the tube surface is not the same as it is in a tubeless tire casing so it is imperative for the tube tire to be in motion for Sahara to fully stop air porosity. Once the air porosity is controlled Sahara helps the tube run cooler whereby it will not soften the tube rubber. This will help the tube to perform better and it will be able to take the pothole impact more easily. This again is similar to how a properly inflated tubeless tire performs.

Q. Will Sahara cause rust or corrosion to the rim?
A. No. Sahara contains high performance superior rust & corrosion inhibitors to protect both ferrous and non-ferrous metals. Sahara will even protect steel belts from rusting after a puncture object has exposed them.

Q. Will Sahara dry out inside the tire?
A. No. Sahara will not dry out. It retains its gel texture for as long as the tire is mounted on the rim.

Q. Is Sahara a tire and wheel-balancing agent?
A. Yes. Sahara is designed to act as a tire/wheel end balancer and acts far superior then traditional metal weights, powder balancing, glass beads, disc balancers or liquid balancers.

With the dynamic balance system you add Sahara inside the tire. The physics statement for this process is: a free floating mass in a spinning assembly will seek equilibrium. In other words it self balances. As an overall concept this system re-balances the assembly each time you accelerate from a stop.

Q.   What will Sahara do in the case of a tread area puncture?
A.   Sahara will seal around the nail to prevent air loss and also protect the steel belts with its anti-rust and anti-corrosion ingredients. Thus with no air loss, the tire retains its correct shape and operating temperature, thereby considerably reducing the risk of damage caused by the nail.

Q. During the next tire inspection process what if a nail is discovered?
A. When a nail is discovered remove the nail (never pull a screw…unscrew it) and rotate the tire by driving the vehicle a short distance of at least 50-100 yards. This will allow the weight of the vehicle to open up the punctured area and let the product and fibers re-seal the leak. The spot where the nail was removed should be visually inspected to determine it is not losing air. The tire pressure should be checked and adjusted if required to ensure correct inflation pressure.

Without Sahara, the nail would cause tire deflation and most likely a run flat situation which could destroy the tire, cause expensive downtime and possibly even create an unsafe driving situation as the tire deflates.

Q. Does Sahara cause ignitability of tire casing?
A. Chamber fires have been a long-standing problem with retreaders and are usually caused by volatile flammable liquids such as ethers and most recently bead lubes that are used to protect rims from corrosion. For these reason all Material Safety Data Sheet contain a column where it is mandatory by “WHMIS” to state the Autoignition Temperature. Retread Chamber ovens may operate at a range from 220 degrees Fahrenheit to 280 degrees Fahrenheit. Sahara’s Autoignition Temperature is 421 degrees Celsius / 789 degrees Fahrenheit. There are no ingredients or chemicals in Sahara that are detrimental to materials used in the manufacture of tires.

ARDL Chamber Test (Test # PN94504)

  • Stallion products do not support combustion.
  • GC/MC Test (ENTNB5-24-1)

Stallion products do not support combustion and will not cause a fire in the  retread chamber.

Q. Does the type of wheel rim have any relevance to the effectiveness of Sahara?
A. Generally not – Some rims are more porous but the product is effective on all type of tubeless rims. Tube type rims must have a tube fitted in the tire.
 
 

Commonly Asked Questions

Q. At what temperature does a tire blowout and tread delamination occur?
A. Constant overheating (even minimal) over time will gradually destroy a casings structural integrity and cause either delamination (separation) or blowout (sidewall or tread).

Q. Is temperature the only cause of delamination?
A. Generally overheating or incorrectly repaired punctures are the main cause. Although not common air pockets undetected from retreading can also be a cause.

Air inflation systems add moisture from compressed air and if a puncture is not repaired immediately the moisture will seep through the injured area and corrode the steel belts eventually causing a tire failure. Impact fracture can also be the cause.

Q. Why do trailer tires appear to fail more often than steer or drive tires?
A. Trailer tires have a greater failure rate due to: extreme load variations and lack of tire maintenance.

Q. Are hot tires more subject to punctures?
A. Yes. Overheating can increase punctures, although operating conditions are the main cause and type of terrain.

Q. Are “0” rings an issue?
A. “0” rings are not an issue. In fact Sahara seals O-ring leaks.

Q. What evidence is available from outside sources to show that any % saving can be achieved?
A. 90% of all tire failures are a result of tire under-inflation.

Almost half of all emergency roadside assistance calls are a result of tire failure,

20% under-inflation reduces carcass life by 30%,

20% under-inflation reduces tread life by 25%,

20% under-inflation reduces fuel mileage by 2%.

Source: NHTSA

Q. Is it possible to establish an average life for a tire?
A. Many tire manufacturers are guaranteeing mileage providing all maintenance factors are perfect. The performance loss varies according to maintenance faults.

Q. What concerns do retreaders have about casings?
A. Retreaders concerns include: casing quality (brands) – casings drying out – casing damage (overheating & number of punctures) – locating previous punctures – impact damage – belt damage – stone/rock damage.

Q. Does the Sahara help prevent this?
A. Yes, Sahara definitely reduces the casing from drying out. Sahara moisturizes the tire casing and prevents it from drying out. Just like our skin; tires dry out with age and chamber heat. By moisturizing the casing, you can extend casing life and even obtain more recaps per casing.

Q. What effect does cold weather have on tire pressure?
A. Tire pressure is affected by temperature changes – both ambient and tire build up. The chamber (casing) volume remains constant but temperature affects the internal air volume. As this air volume increases and decreases with temp. variations within a constant chamber volume, then pressure varies accordingly. The air volume actually compacts and expands.

Q. Do tires bleed more in cold air?
A. Tires do not bleed off air – rather porosity can increase in severe cold – depending on tire quality. Sahara will prevent this.

Q. Does operating temp vary due to size of tire?
A. Operating temp is dependent solely on (1) Pressure (2) Load (3) Speed (4) Terrain.

Q. Do correctly inflated tires run hotter under heavy load conditions?
A. Operating temp is dependent solely on (1) Pressure (2) Load (3) Speed (4) Terrain.

Q. How realistic is it to achieve a 5% saving?
A. Savings of 5-10% are common simply by maintaining correct inflation of the tires, thereby maintaining correct operating temperature and rolling resistance.

Two of trucking’s highest costs are fuel and tires. On a regular semi unit with 18 wheels, even an average loss of 10-psi per tire is the same as running down the road with two flats. You’d never do that would you? Two flats would ruin your tires and run up your fuel bill by making the engine work harder. Properly inflated tires give better fuel mileage and last longer.

Q. What other factors could contribute to reducing costs?
A. Other cost reducing factors – correct mechanical maintenance (including suspension components) – driving habits – correct tire patterns and compounds for driving/operating conditions – correct tire fitment.

Q. How many caps per casing would be considered normal?
A. The number of caps per casing depends on the quality of tire and maintenance program combined with operating conditions. While 1 cap should be a minimum expectation, many fleets would be happy if they averaged 3 caps for every new tire they purchased. Many new tires cannot be capped due to casing failure or damage.  As a result, casing demand is usually high in the retread market.

Q. If a casing is recapped more than once, what happens to the density and porosity of the rubber?
A. Density does not necessarily change apart from the tread area. Porosity can increase in some cases. Drying out of the casing is a major concern.

Q. Does this reduce its value?
Value does decrease. “Clean Skins” – non-capped casings – are worth more.

Q. What factors affect the temperature of tires?
A. The three main causes of heat buildup are: under inflation – overloading and speed. Each of these factors causes an increase in friction, which increases the operating temperature. The volume of air in the chamber is the only factor that assists in dissipating heat and maintaining correct operating temperature.

Q. How much does tire brand affect tire life?
A. Tire brand affects tire life considerably i.e. quality. However, the correct pattern and compound are of equal importance.

Q. Is the casing drier with each succeeding retread?
A. Yes, the casing does dry out with each cap process.

Q. Under what conditions will Sahara not stop bead/rim leaks?
A. Bent or damaged rim flanges and/or damaged/cut beads may not seal.

Q. Does Sahara affect the tire manufacture’s warranty?
A. No. Sahara does not affect the tire manufacture’s warranty. In fact, Sahara has passed the ARDL’s tire engineers test criteria. ARDL is one of the most recognized labs in the world for tire/rubber testing. The test was based on OEM test standards and TMC RP.

Tire manufacturer warranties specifically state that “unless the introduced product damages the tire” it will not affect their warranty. There are no ingredients or chemicals in Sahara that are detrimental to materials used in the manufacture of tires. Sahara’s non-toxic and biodegradable properties do not react against any components used in the production of tires/rims.

 

 

The bottom line is always the cost savings for the end user/fleet operator. Without Sahara, the nail would cause tire deflation and most likely a run flat situation which could destroy the tire, causing expensive downtime and possibly even create an unsafe driving situation as the tire deflates.

The puncture sealing ability of Sahara is only one feature. The product has been designed and developed far in advance of “typical tire sealants” and offers numerous other benefits such as retaining correct tire pressure, wheel/tire balanicing, eliminating air loss through porosity, stopping bead/rim/o-ring leaks, moisturizing the tire casing, biodegradable, non-toxic and environmentally friendly.

Stallion Manufacturing Inc. does not claim Sahara will perform magic and turn tires into “super-tires”. What we offer is a cost-effective option, which can greatly assist in reducing operating costs and downtime.
