Which class are you running Yankee?
Going to build for CAM-C like everyone else this year Hillbilly. SCCA has created a vacuum to that class the way they have the rules currently.

Understeering? Get rid of those itty bitty 245mm fronts!
hehe.... we have sold a LOT of S197 guys a LOT of sets of 18x11" wheels. And lately a lot of 19x11" wheels for people that cannot understand that 18" has better tire choices, or they don't like the look of 18s. ,

Spoiler is too big. ESP is 10", CAM is 8"
Which coincides with USCA's new rule package for pre 89 cars. I believe the late models are limited to 6".
There will probably be lots of good autox parts for sale locally around Jan/Feb that fit your mustang. Like a fays2 watts, some AST4150s and possibly a set of 18x11s with still good 295 rivals mounted on them.
Terry, do you have any customers running the new 285/35/19 Rival size? According to TR, it only puts about 9.5 inches of tread down. Tire selection isn't terrible in 305/30/19 for those wanting to get aggressive. 19" also opens up a new compound (AD08R)
I don't know if this tire has a "rival", hehe. But the available sizes are even more restricted... and different than the "old Rival" in many cases. Again... WTF?
The Rival-S in 315mm and 335mm is pretty much your only answer at the moment for competitive CAM cars.
I wonder what prompted him to start autocrossing. Bored?
I like the Yokohama AD08 and won a lot of races on that tire, but the AD08-R is new to me. They make a 285 and 295 in 18", but a super short 30 series sidewall will cause for massive wheel gaps. And these are 180 treadwear tires, so they aren't legal for almost anything.
Cheers,
The AD08R is even better than the AD08 but limited tire sizes and 180 tread as stated. They handle heat well and work quite well in the wet. Good Daily driver / Track day tire.
Wish they could get with the program and magically turn into a 200 like all the others.
If it then crosses your mind that intentionally under-advertising the TW number for a tire with serious high-performance intent might happen strictly for marketing advantage, or that re-rating any such tires without effort beyond re-working a couple of numbers in the tire molds could happen . . . you just might be on to something.

Thanks Norm -
I have thought this for many years.
NASA / SCCA / ECT - Have to have a way of checking tire ratings. Do you or anyone else know what the procedure is or do they just go by what the tire manufacture states.
Back in the early 80s I was involved with someone with more money than he knew what to do with. He raced with V.A.R.A. which was the largest vintage association at the time. He was a large contributor and had people on his payroll running the board. This gentleman had 100s of tires formed from old molds using newer softer compounds. His racing class was limited on tire size. Anyone can do this and current manufactures, I am sure, supply special tires to sponsored drives. They did / probably still do it in Drifting so I'm confident the practice is standard for other divisions where certain types of street tries are required.
How does a Racing / Sanctioning body check tire compounds for compliance?
