Hi Ross - ((American Racing Slang)) Sticker's are new Slicks or DOT Tires that would still have the manufacturer's "Sticker" on the tread face such as the one shown;
On most race-only tires that I see, there's typically a similar sticker that identifies the size / compound and inspector's sign-offs..
The cars I race are anywhere from 1900# to 3200# - None of them work well long-term on the sticker tires whether they are slicks or DOT Treated tires. When I was a contract driver for BFG - they told me to run no more than 5 fast laps on the tires before letting them cycle for a week. They (BFG) did not believe in the heat cycling services that some places like Tire Rack do.
We're currently preparing a new BMW M3, a Porsche 944 and a pair of Ford Mustangs. The Mustangs will compete in SCCA B-Prepared and Super Production. The heaviest will weigh in at a svelte 3100# with me in it at the end of the race. I'm in at 220 with full gear... Yes - I'm on a workout program now..
Tire sizes are 205 for the lighter cars up to 315 for the SP Mustang.
