I can't find the Ask Al thread. It is not coming up on search function, so I am going to post my question here - it is the tire size question that seems to come up all the time. What impact does changing the tire diameter have on the control systems - speedo is obvious. But the real question is what impact will it have on stability and traction controls. The Camaro team did use a 1LE sizing on the famous GM SS suspension tests they did, but didn't mention if there were any negative impacts or if they reprogrammed the control systems for the change in diameter. If I find the Ask Al threads, I'll bump them there too. But this is such a basic mod that a ton of folks seem to do, it would be great to have an answer.
