Just like it say's what are you running? I have Swampers ssr 37/12.5/16 on 16x10 rims. Ran into a guy this weekend wants to trade his Swampers sx 38.5/14.5/15 for mine his rim size is 15x8 I think they are not wide enough for that tire. I was going to look into a new set of rims monday. So I was thinking the best backspacing would be 2.5 to 3.0 with a D60. So tell me what you are running and what you think about this deal.
