History of Hoosier Race Tire
Hoosier Race Tire has been producing the highest quality race slicks and track tires for more than 50 years. Hoosier is the largest race tire manufacturer in the world, and all Hoosier race tires are still proudly "Made in the USA". Hoosier Race Tire produces over 1000 different types of race tires. The company has its own 300-mph test wheel; a technology testing center; and state-of-the-art, fully-integrated production facilities.
Hoosier Racing Tire's extensive testing has shown the R6 produce crisper steering response and improved transitional performance. Their new internal construction provides increased overall grip and greater stability at the tire's higher limits of adhesion, allowing the driver to apply more power with confidence. The new R6 has also shown better overall wear due to the improved tread profile, The R6 features two symmetric "Formula One" style circumferential tread grooves. Additionally, their symmetric tread design allows them to be mounted on either side of the car (and later be remounted inside out to further extend their life). Beginning with a tread depth of 4.5/32", they will not require shaving for competition, however they will benefit from heat cycling before competition to enhance wear and provide more consistent performance.
Hoosier H2O Hoosier’s Radial Wet H20 is Hoosier's tire developed for drivers who participate in autocross and road racing events in moderate to heavy rain. The H20 tires feature an aromatic oil-free wet weather tread compound that offers traction for fast and consistent lap times in wet track conditions, along with improved tread wear and durability in damp to drying track conditions. This compound is molded into a directional tread design featuring a combination of circumferential and "Y-shaped" lateral tread grooves. Through the initial portion of their life (between their beginning tread depth of 8/32-inch and approximately 4/32-inch of remaining tread depth), the walls of the tread grooves taper as the tires wear. Through the remainder of their tread depth (between 4/32-inch tread depth and worn out), the walls are molded vertically. This allows the tires to serve as full wet tires when used at their original 8/32-inch tread depth, or intermediate wet tires when shaved or worn to approximately 4/32-inch of remaining tread depth due to the reduced tread squirm and increased footprint contact area.
Hoosier’s Radial Wet H20 tires have a symmetric internal construction and directional tread design that allow them to be mounted for use on either side of the car. The tire’s internal structure features a three-ply nylon cord radial casing reinforced by two fiberglass belts and a spirally wound circumferential nylon cap ply under the tread.
WARNING: D.O.T. labeled Hoosier Racing Tires meet Department of Transportation requirements for marking and performance only and are NOT INTENDED FOR HIGHWAY USE. It is unsafe to operate any Hoosier Racing Tire, including D.O.T. tires, on public roads. The prohibited use of Hoosier Racing Tires on public roadways may result in loss of traction, unexpected loss of vehicle control, or sudden loss of tire pressure, resulting in a vehicle crash and possible injury or death. And like all Hoosier race and track tires, R6, A6, H20, road racing slicks, and vintage/historic are not intended to be driven in near-freezing temperatures, through snow, or on ice. It is also essential that these tires be stored indoors at temperatures above 32 degrees fahrenheit.
