Got a set of 17x9.5 wheels. Will be putting probablly a 275 40 on the back. Will I need a spacer or will they fit? How much rubbing should I expect?

 

my firehawk rims clear fine with the bfg kwd's 275/40/17's

 

I'll measure the backspacing. Shoulda done that before I posted

 

It deepnds entirely on the specs of the wheel. Any wheel with the proper specs for a 3rd gen will fit a 275 witout a hitch. Anyother wheel, like a 4th gen or vette wheel, will not just fit witout spacers. I run that size with a 2" drop and have room to go bigger.
