Hello!
I've now 275/40r17 and 315/35r17 on my vette. There is a tolerance of 0,1%

I want to change to the c6 z06 size 275/35r18 and 325/30r19. But there is a tolerance 4,3%

Does anybody knows how big is the tolerance of rolling circumference in the 1992 lt1 asr/abs electronic ?

ECU tolerance unknown.

SWAG: If ASR or ABS lights on after rim size swap a change of ABS reluctor rings (if possible) should work.

I went from 255/45/17 and 285/40/17 on my 96 CE to the sizes you have listed for the C6 ZO6 and didn't get any error codes or problems with the ASR/ABS with them. I had to take them off because I had problems with the rears rubbing on the outer fender wells on hard turns when I hit a dip in the road. After I get the fenders flared, I will go back to the ZO6 wheels. Hope this helps you out.


Cheers
