Simply put, I need to get new tires soon so now would also be the ideal time to get wheels as well. I was thinking of going with 15's just because the tires will last longer than the larger sizes and I now drive alot more than I used to. I can get a really good deal on this set of rims but I'm still undecided on them. What do you guys think? Which offset is best? They come in a 38 or 42MM offset and are 6.5" wide.
