Tire PSI While Towing

Hi Guys. 2018 TRD Off-Road here. Only had it about 2 months. My tires are rated to 51 PSI, but the stickers in the door tell me 30 PSI Front and 33 PSI Rear. My question is what PSIs are good for a truck that is primarily used to tow a 21' fiberglass bass boat?

I normally keep my tires about 45 PSI and haven't had any issues, but I'm about to tow my 21' bass boat for 6 hours one way so I figured this was a great time to ask!

 

45psi for those tires should be fine. How heavy are the boats? After those tires are used up maybe jump up to an e rated tire.

but 45psi when towing should allow you to get the most life out of the tires

 

I have not weighed it on a scale, but it's probably between 3,500 and 4,000 pounds.

 

You should be good then!
