Tire Diameter vs Traction Control - ZR-1 Net Registry Forums

USAZR1 · 04-28-2014

After two months,our new 19" CCW wheels will be shipping out,today or tomorrow. I already have the rear tires,a pair of 335/30/19 Nitto NT-05's,but am trying to decide between their 275/35/19 and 285/30/19 for the fronts. If our 94 didn't have Traction Control,I would choose the wider and shorter 285's but those are approximately 1.25" shorter diameter than the rear 335's. My question is this: how much diameter difference can you get away with before running into problems with the TCS? I know I can just turn it off every time I drive the car but will it set codes by doing so?
There is only about 1/4" difference in height between the 275/35's and 335/35's so there wouldn't be a problem with that combo.
