Sorry for the brain fart. 87 LX, I am going to run street tires, I want the widest tires I can run out back without too much tire sticking out of the wheel well. Want to run 225's up front and 275's out back if I can get the 275's under the fender. I am running 255's out back right now. I didn't know if there was a certain depth from the lugs to the inside of the fender that I could use.
