The amount of air is determined by our engineering department and is not the same for every type of tire Hoosier produces. On this machine each tire has air injected into it for a set period of time. After a tire is cured, it is removed from the press and placed on a machine called a "post-inflator". Now, to understand its use, you need to understand a little of the manufacturing process as well. This is not something that is unique to Hoosier but is common to all bias tire manufacturers. You should inspect your tires every 10-20 passes, more frequently in high horsepower cars.ĪNSWER: As a result of a tire being bias in design (as opposed to radial), it will have a circumference that varies from tire to tire. Cars that launch hard can cause the carcass material to break down.

Your tires have wear indicators in the tread to give you an idea of how much rubber is left on the tire. Inconsistent 60' and 330' times caused by tread wear or carcass break down will be your signals to change the tires. Again this procedure will work for most cars, but fine tuning the procedure for your car may be needed.ĪNSWER: This will vary from car to car. The goal of the burn out is to clean all debris off the tires and heat just the surface of the tread.

Once the tires start to "haze", start to slow the burn out down and proceed to the start line. We recommend rolling through the water box to wet the tires. Not for recreational use.ĪNSWER: With Hoosier's "high traction" compounds, we have found the following burn out procedure to work for most cars. Hoosier Racing Tire products are designed and manufactured for racing purposes only, within a closed course designed for organized competition. Utilizing Hoosier Tires in any form outside of their intended use constitutes misuse of the product and can cause SERIOUS PERSONAL INJURY OR DEATH. All Hoosier Racing Tire products are designed for a specific purpose.
