I also have a 23 LT TB and researched for 2 months on forums of tire companies and TB forums before buying tires. I think the issue/confusion with some not rubbing and some rubbing is the brand of tire and if its MT or AT tires. Some tires have a larger deep aggressive sidewall lug that will rub.
I finally decided on leveling my TB with 1.50 RC level kit with no wheel spacers and BFG "HD-TERRAIN AT KT" in LT285/75R18 "34.8in" tires and I have no rub on full lock forward or backwards. Very pleased with the height, ride and handling.
