I've always had 17's and never had a problem picking the right tire for 17 inch wheels. I sold my SHO so now it's time to spend the money and get some new tires for my LX. I'm getting BFG G-Force Sports. What sizes do you guys run? I was thinkin 225/50 for the front and 245/50 for the back. Anybody got any pictures? Am I choosing the right sizes?
