Abs light comes on Ever since i got my wheels my abs warning light comes on. I can turn on the ignition, and it will reset it. It doesnt come on every time i turn the car on, but it bothers me. Does anybody know why this happens , and is there a fix? I did move up in size for wheels, if that helps.

Tire diameters differ. Fronts are 25.7 inches and rears are 26.1 inches. I don't know how much diameter difference the ABS allows but there is some limit and you may have exceeded it. Could also be a damaged or disconnected wheel speed sensor.
10% difference in circumference seems to be about the
"trigger point" for ABS problems. Asymmetric sizes like the
'vettes will **** it off. Go drive over a tape measure, get
the circumferences and check the numbers / ratio. If it's
that far off, likely it's the problem. If not, start checking
wheel sensors for signs of molestation / loose connections
etc.
