Sup tundra guy, sorry I haven't been on the site in a while.... I'm running 33x12.5/R20s. I had to remove the mud flaps in the front fender well, as well as push the fender liner forward, which I did by unscrewing the front liner screws and the re-drilling through the liner once I pushed it forward. Even then the tires will rub in reverse while turning for the first 300 miles or so. I have run this setup for 4 years or so and it's been fine. You have to rotate the tires every 4K miles IMO.
