Is anyone running the 15 inch Rotas on a big brake car? If you are I assume they clear everything. Next question, I am running the 7.5 23-15 M&H on 6.5 crabs. I need wider slicks. What wheel width are people using for the 8.5 23-15's? What backspacing is needed to run your wider wheel with the 8.5's on a g-body?
My current slicks are getting old (4 years), the edges are nearing wearout from running such low tire pressure and they don't hold anymore (in either 1st or 2nd). The taller slicks might lower my top end rpm too much so I am quite interesting in a retaining the current height but going to a wider slick and what it takes to run them.
Thanks
