Solo® Spec Coupe Tire Care and Feeding
Care and Feeding of Falken Azenis RT615K+ tires
The Falken Azenis RT615K+ is a balanced, easy-to-drive tire that has proven durable in a wide range of applications. The following guidelines will help drivers optimize their tires' performance during Solo® Spec Coupe (SSC) autocross competition and serve as a baseline from which adjustments can be made to suit your driving style, vehicle setup and course conditions.
A good place to start with air pressure is in the low- to mid-30 psi range, depending on the wear you experience. Air pressure can be used to fine-tune the behavior of the vehicle to adjust for driver preference, and all adjustments should be made in 2 psi increments. It's tempting to drop air pressure while searching for more grip, but keep in mind this may lead to tire roll-over and rapid shoulder wear.
Tire pressures should always be returned to the factory-recommended settings before driving on public roadways.
Experience has shown the Azenis RT615K+ provides the best blend of grip and precision when it is kept cool. For tires used in an autocross setting, this typically means around 120-130 degrees Fahrenheit. Tire temperatures should be taken with a probe-type pyrometer. Even temperatures across axles and from front to rear indicate the vehicle is using all four tires equally, and temperatures should be recorded as soon as safely possible after exiting the course. Keep in mind tire temperatures will be strongly affected by what they have done most recently, so if the last turn on the course is a fast right, it will spike the temperature on the left side tires. Similarly, a long, slow drive through the paddock to your spot will tend to equalize the temperature of all four tires.
Tire Inspection Between Runs
Be sure to inspect your tires between runs to monitor tire wear, particularly on the outboard shoulders, and check for scuffing of the sidewalls that would indicate tire roll-over. Look closely for chips, cracks or damage and compare the appearance of the tread pattern on your tires to that of a new tire to help judge how worn they are.
