ABS and Brake light after big tire install
I installed 305/45/18 on my 02 TA and the tires are 28in tall. As soon as I started to drive, the ABS light and the brake light kicked on. I checked the connectors on the back brakes where I put the tires on and they are still connected. Is there some issue with this?

its a common problem when stepping up to a tire that much larger than stock. I just swapped to a 28inch dragradial also and it set my abs and brake lights on the instrument cluster off. Im going to see if my tuner can't work something out when we tune the car this coming weekend.

How much of a difference can you get away with without tripping the ABS or traction control? I have traction control on my TA and I'm thinking about a 17/18 combo, but the overall sizes are going to off slightly. I'm thinking about 275/40-17 and 295/35/18.

theres really nothing you or the tuner can do. I took my gauge cluster out and covered the bulbs up so it wouldnt look like a christmas tree when Im driving. With my slicks and skinnies mine does the same thing, it also affects the abs working properly or at least did on mine.

The problem you're seeing is common. You're ABS system is not calibrated for the tires you've chosen. There is no tuning software available for your situation. Our ABS delete kits cure braking issues and also allow for bias control with the adjustable proportioning valve.

Just deleting ABS isn't a workable solution to me for daily driving. It would be fine for temporary deletion at the track, but that's about it.
The question is how the ABS functions. If it operates based on a difference in speed between wheels, then the issue is just keeping non-stock wheels all close enough to the same diameter and what that allowable range is.

I'm interested in keeping both ABS and Traction Control fully operational. My question is how much that limits my tire choices. If I run the same size tires all around, even if they're non-stock, that "should" still work. There has to be some variance allowed just for going around corners. The question is how much variance in wheel speeds is allowed before it throws a code.
Example, I'm looking at a 17/18 combo with a 275/40-17 front tire. I have a few options for rear tires:
285/35-18 is 0.2" taller in overall diameter - 0.8% difference in wheel speed
295/35-18 is 0.4" taller, 1.8% difference in wheel speed.
I know the 275/40-17 & 295/35-18 combo is pretty common. Does everyone who runs this disable their ABS? How about Traction Control?
