Info about tyres:
The spec tire of SCCA World Challenge GT is the Toyo RA1. It is a shaved treaded DOT tire in various
sizes but in one compound only. There is no “Hard, Medium, or Soft”, and all teams are required to use
the provided tire.
A “Sticker” (brand new tire) will have very good initial grip, but if not properly heat-cycled will then
fade fast, have poor grip, and not last a 50 minute race.
A “Heat-Cycled” tire is a tire that has been run hard for 2-4 laps and then has been left to cool. This
changes the properties of the tire such that it will not have the same high initial grip, but will maintain
its grip level and lifespan over a 50 minute race.
