Re: Rim width?
Art, most automatic trans cars use radials which don't grow anyway. Are you using bias tires? Back in the '70s I first started using wider wheels on Firestone 10.5" bias (all we had then) tires on my C/SM Camaro. It hooked harder and ran quicker with more air, same as my car does now with radials.
Seems like they grew less? I'm very old, so may not remember it correctly. :-(
