History of Hoosier Racing Tire
Hoosier Racing 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 Racing Tire produces over 1,000 different types of race tires. The company has its own 300-mph tire test wheel, a racing tire technology testing center, and state-of-the-art, fully-integrated racing tire production facilities.
Hoosier R7: Hoosier Racing Tire Sports Car D.O.T. R7 Radials (“R7s”) are Track and Competition DOT tires developed for performance and race drivers who compete in driving events where responsiveness and high levels of race tire grip in dry conditions is desirable. The R7 track tires are designed to provide faster, more consistent lap times and extended tire longevity due to the improved tire traction and handling. The R7 track tire features a revised symmetric internal construction that uses nylon cord radial carcass plies reinforced by two lightweight steel belts and a spirally wrapped circumferential nylon cap ply under the R7 track tread.
Hoosier Racing Tire's extensive R7 testing has shown that the R7 produces crisper steering response and improved transitional track performance. The Hoosier R7's 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 R7 track tire has also shown better overall wear due to its improved tread profile. Additionally, the R7's symmetric tread design allows the R7 to be mounted on either side of the car (and later can be remounted inside out to further extend tread life). Beginning with a tread depth of 4.5/32", the R7 will not require shaving for competition.
Hoosier A7 Hoosier Racing Tire A7 radials are very similar to the R7 model, but the A7 is designed to be used in cooler temperatures as the optimal operating temperature of the A7 tread compound is lower. This makes the A7 the first choice for use on autocross circuits where the track is shorter, speeds are lower, and you have less time to get your tires up to temperature. The A7 racing tire is not designed for high temperature environments, which would lead to accelerated tread wear and dramatically shorten the life span of the A7 tire.
Hoosier H2O Hoosier’s Radial Wet H20 is Hoosier's racing track tire developed for drivers who participate in autocross and road racing events in moderate to heavy rain. The H20 race 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 Hoosier racing 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 H2O tread depth (between 4/32-inch tread depth and worn out), the walls are molded vertically. This allows the Hoosier race tires to serve as full wet tires when used at their original 8/32-inch tread depth, or intermediate wet race 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 of the Hoosier H2O race tire.
Hoosier’s Radial Wet H20 race tires have a symmetric internal construction and directional tread design that allow them to be mounted for use on either side of the race car. The Hoosier H2O racing 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 racing tread.
Non-DOT approved Hoosier racing rain tire. Deep groves combined with a soft compound result in maximum race tire traction when there is standing water on the race course. Consistent standing water is required to maintain optimal operating temperatures. Without standing water, these Hoosier racing tires will blister, chunk, and perform poorly as they will overheat.
Hoosier Racing Slicks come in eight tread compounds, ranging from R25B(softest) to S100 (hardest). Hoosier racing slicks provide excellent grip superior to that of other racing slicks. They each optimal operating temperature quickly and provide even and consistent traction throughout their race life cycle. Hoosier racing slicks are, quite simply, the best racing tires available.
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 racing tire pressure, resulting in a vehicle crash and possible injury or death. And like all Hoosier race tires and track tires, R6 racing tires, A6 racing tires, H20 racing tires, road racing slicks, and vintage/historic racing tires are not intended to be driven in near-freezing temperatures, through snow, or on ice. It is also essential that these racing tires be stored indoors at temperatures above 32 degrees fahrenheit.
