Compared to the original Tech R tires, Tech R^A radials are further tuned to make the most of the narrower Original Equipment wheel sizes utilized in the Stock classes & are designed to reduce times by blending great dry traction with improved steering response & cornering stability without a reduction in treadwear.

On the outside, Tech R^A radials feature a more responsive, high grip racing tread compound molded into a symmetric tread design featuring a "slick" tread surface with two circumferential tread grooves. This maximizes their contact area with the track & allows them to be mounted on either side of the car. Beginning with a tread depth of 4/32", they will not require shaving for competition, however they will benefit from heat cycling before competition to enhance wear & provide more consistent performance.

On the inside, the Tech R^A radials feature a revised symmetric internal construction & casing profile that includes a deeper "rim recess" bead design. Tech R^A radials feature twin, lightweight steel belts reinforced by spirally wrapped nylon along with a carcass that adds an aramid- & steel-reinforced sidewall filler to three nylon cord plies to resist deformation at high speeds & when cornering.

The performance of Tech R^A radials is not compatible with the original Tech R tires & the two should never be mixed on the same vehicle.

NOTE: While the Tech R^A radials have an inflated shape with rounded shoulders to complement camber-challenged cars, they still benefit from vehicle alignments that offer significant negative camber.

*Avon Tyres Racing enjoys a worldwide reputation for success on the track, & supplies race tires for F.I.A., Formula 3000 & the global Formula Ford series in addition to many racing series in the USA, including SCCA National & Regional Club Racing. The popularity & reputation of Avon racing tires continues to grow as more than 100 overall Championship winners are regularly recorded each year in more than 27 countries.

**Caution: While Tech R^A radials meet U.S. DOT requirements, they are not intended for highway use as the expected miles of wear from their racing tread compounds is greatly reduced. The Tech R^A is not recommended for driving in wet conditions where there is the risk of hydroplaning. Drivers should drive cautiously at reduced speeds in these conditions.
