Going to purchase new tires to replace re92's. Tough time
deciding what size 205/55/16 or 225/50/16. I know 225's will handle better, but will acceleration be decreased? Looking at Continental Extreme Contacts.
Theoretically, with very sensitive equipment, you could find a decrease in acceleration. In real life, it will go unnoticed. What you will notice, however, is improvement in everything else. Cornering, responsiveness, wet traction, dry traction, look, etc... Make the upgrade to the 225s - that is my opinion.
I have to rely on our customers here - as I haven't driven on them yet. They are getting great reviews from everything I've seen and everyone I've talked to. They are well designed and I'm expecting them to be great. I would indeed recommend them but I can't yet give you my honest opinion on how they drive.
If you are staying with the stock 6.5" width wheels, I think with 225's, you'll get a trapezoidal sidewall profile, i.e., the width where the tire meets the wheel is narrower than where the tire meets the ground. The sidewall may not be vertical enough for optimal performance out of the tire.
