Default ABS INOP and TCS off after high speeds...

I noticed this after more serious racing, drag radials, line-lock, and burnouts.

Sometimes the ABS INOP and TCS off light would light up and the end of the 1/4. After restarting the car it turned off.

Lately, it will come on while high speed driving for long periods of time, usually around 80-85 mph seems to do it.

Anyone know why? Mods in sig.

If your tire sizes are off by half an inch, the tcs/abs will shut off. It realizes that it cant figure out how much brake proportioning to put to each tire because theyre all different sizes.

The fronts are older than the rear. It does it on my WS6 wheels with nt 555's, and only 18" zo6 combo with KDW's and BFG drags, those are new also.

Point is: are the tire sizes different in overall circumference? are they each inflated to suggested PSI if they are the same size?

Yes, as far as I know they're inflated equally.
