315/70/17 question

[CLAYTON]

I have around 1200-1350 lbs of tongue weight with the 5th wheel and was wondering how much psi you would put in the tires. Front? Back? I think the tire says 55 or 50 psi cold. I've been towing at 50psi. Thanks in advance. Off to Aspen today for the 4th of July weekend.

I recall the BFG's being D rated for a max PSI of 65. You could probably get by with 55 PSI with that load, but running at 65 PSI will give you an extra safety margin.
