I have a 2020 limited (eco) with ORP, no lift or level, not much towing involved either. Preferred the 3.92 gears also as wanted to go bigger in tire size. Did quite a bit of research as any bigger size falls into LT 10 ply category and weight penalties of at least 10 LB per tire. In addition, bigger than 275 meant larger contact patches and loss of MPG (The reason I wanted to stay with 275). Noise is also a concern since I do long distance and can't stand drone in the cab. Only two tires that I could find that remain close to the 49LB per tire for Falken WP ie Nitto Terry Grappler G2 P275/65-20 (47.7lb) and Nokian Rotivva AT Plus (52lb, LT tire). The 275-65 is a 2 inch bump to original size and no rubbing etc. This also effectively reduces Axle ratio to 3.7, much more desirable for both power and efficiency for my needs. Ended with Nitto, nice quiet ride and no differences in experience. MPG on same route, mix of country and interstate was about 1MPG better. Calibrated via Rough Country and speedometer is smack on, used the height with truck weight and 34psi. Hope this helps anyone trying to go this route. I will have some pics loaded later.
