TIRE SEALANT FAQ’S
Does Permashield Tire Sealant prevent flats from nails?
Yes. When a puncture from a nail or similar object occurs in the covered area, the inside tire pressure forces the Permashield™ Tire Sealant into the wound area, immediately forming a protective seal around the penetrating object. If the penetrating object falls out or is removed from the tire, the puncture wound is forced open and the product instantly fills the hole and creates a permanent seal.
Does Permashield Tire Sealant prevent flats from screws?
Yes. In a case where a screw has caused a puncture, the sealant will form a protective coating around the threads. The tire will continue to perform as normal with the screw inside, permanently sealed. We recommend that it not be removed from the tire. The head of the screw will wear off as the vehicle is driven and it will not do any damage to your tire. Most drivers will never even realize they ran over a screw because their tire will not lose air pressure.
If driving with a screw inside your tire makes you uncomfortable, or if multiple screws are embedded in the tire causing an imbalance, you may simply have them removed by a tire professional. In most cases, the hole created when removing the screw will seal itself. However, if removal of the screw results in a large hole or a jagged tear in the tire, it may require a patch. Always consult the tire manufacturer safety guidelines before patching or repairing any tire. Any manual removal of the screw that results in damage or an unsealable hole in the tire is not covered under our product guarantee.
Does it cause wheel imbalance?
If installed by one of our trained installation experts at an authorized Dealer or Service Center, the Permashield™ Tire Sealant will NOT cause a wheel imbalance. It is important that all wheels and tires are balanced prior to the installation of the product. In many cases, the sealant improves the driving experience and hydrodynamically balances the tires. Over time, as normal wear and tear occurs on a tire, the product actually works to improve the ride comfort.
Will it protect a tire’s sidewall?
While it is possible for the Permashield™ Tire Sealant to seal punctures in a tire sidewall, for all passenger vehicle and high speed vehicle applications we recommend that any sidewall puncture be inspected by a tire safety professional. It is important to understand that the construction of a tire’s sidewall is very different from the construction of the tread area, and there are structural and safety considerations that make it outside of our product performance guarantee.
Will it affect my tire’s warranty?
We are aware of no major tire manufacturer warranty that is affected by the use of the Permashield™ Tire Sealant. In most cases, the sealant improves the performance of the tire and extends its useful life.
What’s the difference between the Permashield™ Tire Sealant TS series and the Permashield™ Tire Sealant HD series products?
The Permashield™ Tire Sealant TS series formulas with DuPont™ Kevlar® fiber are designed specifically for passenger vehicles and work with all major tire pressure monitoring systems (TPMS). They are designed to maintain or improve tire balance and ride characteristics in both slow and high speed driving conditions. They will prevent flats from punctures up to 1/4″ (6mm) in diameter in the protected tread area.
The Permashield™ Tire Sealant HD formula with DuPont™ Kevlar® fiber is an industrial-grade formula designed specifically for industrial and commercial uses, such as construction, mining, farming, trucking, and other large vehicles. It is also designed for ATV and similar off-road vehicle use. The HD formula works under extreme conditions and can seal punctures in the protected area of the tire of up to 1/2″ (12mm) in diameter.
Will it cause TPMS failure?
We have never had a TPMS failure caused by the use of our product. In the event that our product caused the TPMS to fail, it would be covered under our product guarantee.
How long is the Warranty?
Each installation of the Permashield™ Tire Sealant is covered by our Limited Warranty for 3 years from the date of installation and covers repair or replacement of any tire due to the failure of the sealant to perform. Details and registration information are provided on the Limited Warranty Coverage information documents for each product. Dealers may also offer an additional warranty policy.
See Limited Warranty Coverage for further details.
Is the Warranty different than Road Hazard Coverage?
The Permashield™ Tire Sealant Limited Warranty Coverage is different than a typical road hazard policy sold in F&I. Our manufacturer warranty guarantees that the product will prevent flats caused by punctures up to ¼ inch in light duty vehicles and ½ inch in heavy duty vehicles that occur in the covered tread area of the tire, if properly installed. Side wall damage and flats caused by potholes, lacerations, or other similar scenarios are not covered.
A typical Road Hazard policy will cover flats or tire and wheel damage caused by any number of reasons that fall outside of our product guarantee. It is very common for dealers to sell Road Hazard policies in addition to installing the Permashield™ Tire Sealant for maximum coverage. The installation of the Permashield™ Tire Sealant often results in lower Road Hazard policy claims, and therefore, higher warranty profitability and retention.
Can I pre-install product in all of my vehicles during PDI?
Yes. However, in order to activate the Permashield™ Tire Sealant protection the vehicles must be driven for approximately 5 minutes above 50 miles per hour to properly coat the inside of the tire. If a vehicle sits on a lot for an extended period of time it may be necessary to drive the vehicle again to reactivate the protection.
How long does it take to install the product?
Typical installation takes less than 15 minutes.
What is the process for a customer to submit a claim?
All customers must register their vehicles through our online registration link. They will then be given Permashield™ customer service and claim contact information.
Does Permashield USA, LLC pay claims to the dealership or the customer?
Customers have the option of receiving reimbursement directly or having payment made to their service provider.
What about extreme temperatures?
The Permashield™ Tire Sealant has been extensively tested and is certified to -40 degrees F without freezing. It also remains stable and effective at temperatures up to 150 degrees F.
Are protected tires repairable and retreadable?
Yes. Unlike many of the competitor products, any tire with the Permashield™ Tire Sealant installed does not cause it to be unrepairable or unretreadable. The product is water soluble and may also be removed with a simple hose to allow for any needed repairs or retreads.
Is it safe?
The Permashield™ Tire Sealant is non-toxic, non-hazardous, and non-combustible. Not only does it comply with all Toxic Substance Authority requirements, but many of its ingredients are commonly found in food products and other household items. All of the Permashield™ Tire Sealant products also include rust inhibitors that prevent the product from causing any corrosion or degradation of wheels and modern, sealed internal tire pressure monitoring sensors (TPMS).
Can I use Permashield Tire Sealant on a run-flat tire?
Yes. Run-flat tires provide no flat tire prevention. Run-flat technology typically involves a stiffer side wall or inner supporting ring. Neither of those technologies cover the tread area that Permashield Tire Sealant protects. Permashield Tire Sealant will prevent flat tires that would otherwise cause the run-flat technology to be used, thereby increasing the life of the tire and preventing costly and time-consuming tire repair or replacement.
Is Permashield Tire Sealant protection better than a run-flat tire?
Yes. Run-flat tires do what they claim to do: run when flat from a puncture. However, you still have a flat tire and there are a number of problems with the run-flat technology. First, when flat, a run-flat tire is only designed to run for a few miles and at a reduced speed to allow the vehicle to reach a nearby repair station. Second, the longer the tire is driven while flat the more likely it is that the tire must be replaced. When flat, run-flat tires run hot and can damage the inner layers and side wall integrity. Third, replacement of a run-flat tire is very costly and not all repair stations have them in stock, resulting in inconvenient delays and multiple trips to the repair station.
Permashield Tire Sealant prevents flats. There is no need to reduce speed or find a repair station in nearly all cases. Once the sealant seals the puncture, there is no need for any further repair to the tire under normal conditions. This means no down time and no costly replacement or repair expenses.
