OK, so I just got my truck back from getting the spacers installed (along with shocks, u-joints, and wheel bearings...) and it rides rougher than I expected. (I'm not complaining, just wondering if that's normal?) Anyways, my main question is about tires. Right now I have 285/60-18's on. Which is like a 31.5 x 11.5" tire. I have a few different sizes in mind. I'm looking at 305/60-18's, and 325/60-18's. The 305's are like 32.5 x 12", and the 325's are like 33.5 x 12.8". Do you think the 325's will fit? I'm hoping they do. What do you think?
