So I am going to be picking up my new to me TT here in the next week or two and I am wondering about if I need to do anything with the tire pressure on my TV before towing. The TT that we got is about 24' in length and has a dry weight of about 3,500 lbs. Normally I just put in about 5psi below what is stated on the door of the the truck. I know on the actually tire it has a max psi of much greater. So in all I think I normally have them set about 35 psi. Am I going to need to worry about adding more air than that for towing or should I be okay with that setup and my TT size and weight? Right now I have the factory BFGoodrich Rugged Trail T/A 275/65/R18 tires on the truck. Thanks,

What is the maximum pressure of your tires, that's what I would run.

I have a lot heavier truck and TT, but I typically air my TV up to max sidewall pressure of 80psi (I have e-rated tires)... The sticker on my door calls out 55psi unloaded and 60 front/70 rear loaded....
When I had my 1/2 ton TVs I always ran the tires at max pressure when pulling... Also ran LT tires (d-rated) not passenger tires...

Run the max that is stated on your sidewalls.

Well I went out and looked and the tire even stated that the max PSI is 35 and each tire stated that the max load is 2,601 lbs. So I guess if I just put in the 35 I should be fine??

My tires are E rated with 80PSI max stated on the sidewall of the tire. I always tow with front at 75# and the rears at 80#.

Are the passenger tires (P) or light truck tires (LT)???
I would guess with the 35psi max, they are passenger tires maybe?? A D-rated LT tire would have a max pressure of around 60-65psi.

I as well would assume they are passenger tires.

I must disagree. The idea is to have the tread of the tire flat, for even wear. I would follow the tire pressures given on the data plate or the Owner's Manual. If you are running at maximum load for your tires, then you should have the pressure noted on the sidewall. For anything lighter than max load, your tire tread will be bulged in the middle, which will increase the wear in the middle of the tread, and lessen the contact patch, resulting in less traction. Less traction will induce more slippage, resulting in even greater wear.
I find that following the truck manufacturers recommendations on tire pressures gives me better traction and increased tire life, not to mention a better ride.
However, to each his own. Ultimately, the decision is yours.
Good luck.
