Weigh your combo loaded and TV seperately. Use tire weight/inflation chart.
My Ram 2500 4x4 Cummins empty 72 front 45 rear rotate about 15k. Michelins or BFG's I easily get over 100k on a set. I would guess for you 65 front.
I go with Cummins12V98 on this subject! The door post is for MAXIMUM load not daily driving. Running the rears at 70 empty, will;
shorten tire life

Thanks!
