Sorry to keep this thread going, but it seemed like the best place for this. I'm looking to order tires for my '63 Avanti. I recently got the new Real Rodder wheels, so they are wider than the stock wheels. I'm going with an R-3 clone engine 4.09 TT rear end and Tremec five speed tranny and looking for the widest wheels I can put on the rear to improve traction on launch. I understand the front wheel size is somewhat limited by clearance issues, so if I go as wide as I can in the rear the fronts will be a little more narrow. Looking for suggestions as well as "Pros & Cons", of various choices. What have others used, and are you happy with the result?
