Hoosier A6

Hoosier Racing Tire Sports Car D.O.T. A6 Radials are Track & Competition DOT tires developed for drivers who compete in autocross, time trial and hillclimb events in dry conditions where providing responsiveness and high levels of grip at lower operating temperatures is desirable. The A6 Radials are designed to give the driver significant performance advantages over previous A3S05 tires in autocross competition. The A6 Radials feature an improved tread compound molded into a "slick" tread design featuring two symmetric "Formula One" style circumferential tread grooves. A more rounded tread profile extends the life of the shoulders and produces more consistent tread wear across the entire contact patch. The A6 radials feature 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 tread. The tires feature a "rim recess" design on all sizes. Hoosier Racing Tire's extensive testing has shown the A6 Radials produce crisper steering response and improved transitional performance. Their improved tread compound delivers more consistent run times over longer exposure to heat and less degradation of grip after several runs. 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 A6 Radial has also shown better overall wear due to the improved tread profile and the increase in overall grip. 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). Hoosier Racing Tire's testing has also shown performance will be improved by using lower operating pressures compared to A3S05 tires. Hoosier advises competitors to lower air pressures in small increments to find optimum air pressure for their specific vehicle. Beginning with a tread depth of 4.5/32", they will not require shaving for competition, however they will benefit from a minimal scuff-in prior to their first runs. NOTE: While the A6 Radials have an inflated shape with relatively round shoulders to complement camber-challenged cars, they still benefit from vehicle alignments that offer significant negative camber. WARNING: DOT 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 DOT 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 possibly injury or death.
