Searched, but didn't find what I was looking for. Question is how much differance can you have between the front tire and rear tire in diameter before it affects the computer? Reason is, I have to order new rear tires. I corded them at my last trackday. The front tires are 275/35-19, 26.6" in diameter, and they are still good. The old 325/30-19's are 26.7" in diameter. Wondering if I could go to 345/30-19, 27.2" diameter without the lights coming on.
