Yea you got that right. Very expensive. I've considered 265 70 17 but I think ultimately I would like to go to 285 70 17. I had a similar size on my old 1500hd, (285/75R16) and I though they were the perfect size. So I'm trying to get as close to that as possible. They fit perfectly, all I had to do was trim the plastic valance on my 06 1500hd and it fit perfectly and really looked good in the wheel well. But on this 15, don't feel so good about trimming it up with only 10,000 miles lol.
Any way you could post a couple pics so I could see how it looks with the 265/70r17?
