Well that video tells me I can do a 34.5x12.5 if I go to a different offset. I want to stick with the stock offset so I don't know if <1/2" will matter. If I'm understanding the video correctly it sounds like we could run a 35"x12.50" that is the same size as the 315/70R17 he quoted. I would love to know if anyone has done this and can confirm it fits.
