I need to replace 4 tires 205/60/15 on my 92 Vigor, auto GS. The tires brand new run about $300. I was thinking maybe of switching to larger wheels. What is a good size to upgrade to, 16 or 17in? and what is a good size for the tires, 50's or 60's? I am on a low budget and am thinking of maybe buying a set of used wheels. I live in the LA market and there are a lot of used wheels out there, especially from late model cars where people have upgraded to 20's. Does anyone have any ideas?
