When you mount the 255 on the front, where does it rub? On the spindle support or on the body somwhere? I would like to know because I'm setting up the car for SCCA circut racing and I don't need tires that rub on the spindle support.Tires are the last thing I need to get.
255's will not rub if your wheel offset is right. I have about 3/8 of an inch between the rear sidewall of my tire and the upper ball joint knuckle. I'm running 255/50-17 BFG G-Force KWDS tires on mine.
For starters, the stock on an LX is 215/70 15. Well, I went to 17's and put 225/55's on it. The tire diameter's are almost identical (I mean off by like .05 inches or something). I used this site http://www.c5-corvette.com/tirecalc.htm . Put in your stock height ( I think on SC's it's 225/50 16, not sure), and then the size(s) you are debating and it will tell you how far off from the original size you are. It will also help you out in discovering how far off your speedometer will read. I went with the size because of it's small, small change, and my speedo reads accurately still. And yes, 255's are the widest on the front, and I have read of people going as wide as 285 on the rear. Hope this helps.
