Different size tires on fbody = ABS Inop Light? A friend got two different sized tires on his new wheels. The rear has a diamater of approx 27" while the front has a diamater of about 25". On the highway, the ABS INOP light illuminates. I know the vettes have different tire sizes, can this be tuned out?

To put in another way if you use P275/45/17's in front you can use a P275/35/18 in the back and the overall wheel/tire size is almost the same. If you used a P275/35/17 in front and a P275/35/18 in back that changes the overall height and the ABS will give you issues.

You can change the size of the wheel to smaller or larger, but as long as the tire profile compensates for it and the overall diameter stays the same, you're fine.
If you start changing sizes and the car knows this? It isn't going to function properly.

The wheels/tires need to be close to the same diamater or the ABS will not work in an fbody. Pulling the fuse is the same as what your friend has now, no ABS. Your two options are have the tires/wheels be the same approximate diameter front and rear or live with the ABS not working. You can certainly pull the fuse, pull the bulb but the result is the same unless you fix the mismatch. Probably not what your friend wants to hear but those are his only real options.

Remove ABS, it is going to drop up to 20 lbs w/traction control. Even by just pulling the fuse, you're brake bias will be off..
Since ABS nor traction control will function no matter what, there is no reason in having dead weight on the car. We've got ABS delete kits priced as low as 139.99 for the entry level kit which enables you to completely remove ABS. All kits include a proportioning valve and pre-formed lines w/all fittings necessary. They are all setup to work with a line lock too!
