In recent years, performance street tires have come a long way. The amount of performance that can be had from new age Extreme Performance Summer tires has lead to rapid growth in competition classes that mandate street tires with a UTQG treadwear of above 140. These tires, which can be driven on the street, allow drivers to commute to their local autocross events or track days without bringing along wheels and tires to change out. Tires such as the Hankook Ventus R-S3, Dunlop Direzza Sport Z1 Star Spec and Bridgestone Potenza RE-11 have been very popular choices for drivers demanding street miles and acceptable levels of track performance.
For drivers that are looking to expand upon the traction threshold of a street tire, a race compound or R-Comp is your next step. Offered in UTQG treadwear numbers ranging from 0 to 100, race tires sacrifice mileage for softer tread compounds that focus on maximum dry grip.
Recently, Tire Rack came into contract with Toyo to offer their motorsport line of products. This allows us to sell their new Toyo Proxes R888, which has been a popular choice for racers seeking an intermediate race compound that finds a happy medium between lap times and longevity. With a UTQG treadwear rating of 100, these tires are softer than a street tire and provide improved dry performance all while still offering a good amount of seat time. Compared to a shallow tread designed tire like the Hoosier R6 (UTQG 40), drivers can expect superior wear and better wet traction. While the Toyo may not be ultimately as quick in the dry compared to a Hoosier R6 or BFGoodrich g-Force R1, they are more cost-effective, longer wearing and endorsed as a spec tire for many racing bodies such as the SCCA and NASA.
Available in a large range of diameters and widths, Toyo's Proxes R888 should help fill the gap between a competitive street tire and the most extreme of road race compounds.
