Largest tire for air suspension

[1BADRAMLIMITED]

Ive got 35” Ridge Grapplers on 20” wheels and have very, very minor rub on very rare (read so minor and so rare that I haven’t bothered to try and find out where) occasions. My truck is leveled with pucks and air links. All I did to mitigate the possibility of rubbing before I bought the tires and wheels was follow some guidelines posted in a few places, which suggested warming the plastic wheel liners with a heat gun and gently reshaping them in the front. The truck is a 2019 Limited.

WHAT BED TOPPER IS THAT?
