Hoosier Racing Tire Sports Car D.O.T. R6
Radials are Track & Competition DOT tires developed for drivers who
compete in road racing where responsiveness and high levels of grip
in dry conditions is desirable. The R6 Radials are designed to
provide performance advantages over previous R3S05 tires by
rewarding drivers with faster, consistent lap times and extended
wear due to the improved traction and handling.
While the R6 Radials use the same successful tread compound as the
R3S05 tires, it is molded onto a more rounded tread profile that
extends the life of the shoulders and produces more consistent tread
wear across the entire contact patch. The R6 radials feature a
revised symmetric internal construction (shared with Sports Car
D.O.T. A6 Radials) 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 R6 Radials
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 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 R3S05 tires.
Hoosier advises competitors 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 heat cycling
before competition to enhance wear and provide more consistent
NOTE: While the R6 Radials have an inflated shape with relatively
round shoulders to complement camber-challenged cars, they still
benefit from vehicle alignments that offer significant negative
Hoosier Racing Tire Sports Car D.O.T. R6 Radials are scheduled to
become available shortly after the March 27, 2006 release of the
Sports Car D.O.T. A6 Radials used in autocross competition.
Estimated arrival dates by size will be provided when they become
