Im planning to get 17 inch Primax 618 wheels and I want to get 225/45/17 tires. Buy the looks of the rear suspension the tires wont seem to fit that suspension piece. How do people stick 18 and 19 inch wheels and tires on there?? Offset?? What is that. A spacer or something??? I kinda want to get these purchased so the wait for mail wont be too much longer so please help me get my 95GS some new shoes!!!
