I'm thinking manufacturer limited cheap "spec tire" again to keep the playing field level. I also see frequent tire shaving. My AS tires came as 11/32" tread and were pretty good at autocross all the same with a ton of squirm and heat build. Great in the rain and got me my only AS tire sticker for 3rd in a downpour against several superior cars.
Devil's advocate:
So I'm new to the sport with a daily driver Yaris or just have a Fit (pun intended). The first 2-3 times I have a barrel of fun in S5. If I show up the 4th time I realize I'm no longer getting much faster and I finish DFL or worse but still enjoy flogging on my 80k OEM 600 green tires. I either get new cheap wide wheels and 200 tires to be sorta competitive or I keep it an occassional fun thing to do like driving rental carts on the gas money I saved driving my econobox. I hear of the small tire SH205 (shithouse) class and get all excited. I show up as usual on my regular OEM tires. I initially don't know who's in the SH class because most autocross cars fit that general description and FAST only uses numbers. After the first run I walk to the computer all smiles and see I'm still DFL by 3 or 4 seconds. Some alien redhead is driving a fat red Nissan on 205 F1 Raintyres and vying for FTD against Fred somebody on AS motorcycle rain tires. No one is running in MO at all. So I sign up for regular MO next event and get my 1st Place sticker running against myself. Success at last. I have finally beaten the system and I have a sticker to prove it.
See yall in May.
