Hi,I recently got a new TV--a Toyota Tundra Rock Warrior. It came with the offroad package and LT tires.I tow a 5k pound trailer (dry). What do you recommend for tire pressure both towing and non-towing?I know that LT tires come with a recommended max pressure that is quite high, but is this what I should inflate them to?Should I keep them at 32psi for daily driving like a regular passenger tire?What do you recommend?thanksMatt

Go with what the sidewall of the tire says.Unless it is an E rated tire. Don't need 80 lbs for that.

I personally go max pressure even on E rated tires and here is why.1. I tow in hot weather (90 degrees is the norm) and the more pressure means less heat and less chance for tire failure.2. The higher pressure you go means better fuel mileage and that is always a good thing. Now I know this is a very small effect but every little bit helps when towing.I know that some will disagree with my max pressure advice and show load pressure charts and all of that and that is fine but max pressure works for me.

X2 on the high pressure. My load range E, state 80 max PSI on the side wall. My door sticker says 65 PSI. I get better ride, better hauling, and better towing, with 75 to 80 PSI.Have to watch the grease monkeys, when I get oil changed. They always check the door sticker and let air out of my tires.

For daily driving, go with the recommendations of the folks that built the truck- as is recommended by every tire manufacturer. They don't presume to second guess the folks that designed the vehicle. Lots of folks forget that tires are an integral part of suspension system design, and ordinary operating pressure is figured in the design process for maximum ride comfort/performance etc.For towing, inflation can be increased according to load.

Understand that you are comparing two different classes of tires

The 'P' class, or passenger car tire, needs to be de-rated a min of 9% when used on a truck

Truck tires, 'LT' class, do not

They also work differently and need different PSI's at the same weight carry

The OEM drivers door label is for the tire listed on that label.

If your door label says a 'P' class and you have a 'LT' class...then the door
label's PSI is NOT for your tire

Having too low a PSI can create too much heat to cause a potential failure

I personally go max pressure even on E rated tires and here is why.

1. I tow in hot weather (90 degrees is the norm) and the more pressure means less heat and less chance for tire failure.

2. The higher pressure you go means better fuel mileage and that is always a good thing. Now I know this is a very small effect but every little bit helps when towing.

I agree with the max pressure as indicated on the side of the tire. I run LT "G" rated tires at 110 lbs. Running below the max pressure also creates more heat which is the major cause of blow outs in many cases.

What load range are the tires on TV.

What does the door sticker say for loaded and unloaded psi.

I know that LT tires come with a recommended max pressure that is quite high, but is this what I should inflate them to?
Some like the ones on my Jeep load range C max at 50psi., so not all LT tires are really that high in pressure need to know load range.

Should I keep them at 32psi for daily driving like a regular passenger tire?
Again one needs to go by either the door sticker or owners manual.

What do you recommend?

thanks
