Here's my dilemma... I had a bad alignment when I was running 305 35 18 with 3/8 spacer. Car looked good. I just bought new 315 30 18s and put my spacers back on, I really did not think I would need them believing the tires would be wider. Well they do not appear so. For whatever reason the 315 look smaller.... strange! Either way I have them now and wondering if any one has some pictures or in sight as to why this is and which width spacer I should go with .5" or 1". I have 3/8" now. Looking for pictures of 315 30 18 proxy 888 on afs with 1" or .5" spacers thx. Wish I just bought 305 35 again. That won't happen again.
