I'm pretty sure I will need a 28 inch slick, problem is, I don't know if I can actually fit a 28x10.5 I just bought some weld pro stars ( $170 for all four rims and tires. SCORE!!!!) And they are 3 1/2 with a set of 15x10 with 7 inches of backspace. On the back now are 295/50/15. They are a smidge too wide. I want to go with ET streets. I'm just real curious because I've never bought a slick. I saw some 28x11.5 and the tread was 9 in. those would fit just fine. But it's hard to tell when everyone says 28x10.5, is that how wide or how wide the tread actually is ? Or just what have you guys been able to fit with out tubbing?
