I'm running LT275/70R18 BFG TA KOs (1st gen) on my T for the last 10k. They're E load range tires, as most in the LT in that size are. I noticed last night my fronts are a little low due to the temp drops here recently, but I've had great performance out of mine setting the fronts at 42 cold, and the rears at 35 cold. Everybody said my TPMS would flip out but so far, I'm still getting readings on all four tires, and no warning lights or anything. I'm also getting even wear both in the front and back, which is how I got to the different pressures. We just don't have much weight on the rear, compared to the front. I'm in a 2011 CC so I should theoretically have the most even weight distribution, but its still biased forward quite a bit.
