5.0 First reaction to Mickey Thompson Baja Boss A/T

I have a 2017 GMC Sierra Z71 with from end leveling kit. Purchased 275 65R20 and waited about month to before they came in. Sized up for a little more aggressive stance and have minor rubbing when wheel is cranked all the way over. The aggressive sidewall grabs the inner wheel well but enough for concern. Came off a set of 275 65R20 Patagonia M/T which were a good ride for mud terrain tires but these are hands down the best tires I have ever purchased. The only terrain I have yet to try is snow but based upon my mud trials I fear not. Excellent traction all around including rain soaked streets. Road noise is minimal for such and aggressive A/T. Would recommend to anyone looking for mud terrain efficiency without having the mud terrain road noise.
