Tire Pressure

[ralderman]

What do you run when towing? I have a 13k 5th wheel, should I run 80psi or stock?

I would run 80 lbs in the rear, over 70 lbs in the front.

I just got a new set of tires and my tire guy said 60 front 80 rear. But you just need to use whatever feels solid running down the road and is not wearing funny.

I've never towed that much but I have pulled ~9,000 lbs all over this great country. I always left them at the stock PSI. The tires are rated to handle the weight.

Hook it up, put a chalk line or paint line down each tire tread (perpendicular) and drive so the tire rotates a few times or until you see where the line starts wearing most.
Wearing in the center too much, too much air pressure, let some out.
Wearing on the sides too much, too little, put some in.
The tag on the door is for OEM equipment 'recommendations.' You have different tires then forget that number.
