TV tire pressure?
Hi all -
Quick question if anyone could be of assistance. What do you all inflate your TV tires to when towing? Do the back tires have more pressure? Are they all the same pressure? Should they be inflated to max pressure like the trailer? Thanx for any help!

I keep mine inflated to the vehicle manufacturer specs on the drivers side inside door jamb sticker. In my specific case the rear are at 5# less than that of the front due to having 4 in the rear.
If however your tires were upgraded to a higher rating than what was orginally put on your vehicle from stock then you could go to a higher pressure provided your rims are able to handle that additional pressure. The rims should be stamped somewhere inside for their ratings. When in doubt go with stock pressures.

All tires have "Max load XXXX lbs at XX psi cold" Lower tire pressures cut into your fuel economy and can cause heat build up and sidewall issues. The tire was designed to perform at the stated pressure, so run 'em.

You can run the tires up to what is stamped on the tire.
The manufacturer recommendations on the door jam are based on ride comfort.
If you don't mind a slightly stiffer ride, you can go up to the rating on the tire.

On vehicles equipped with lt tires, I believe that the psi on the door jamb is set according the the vehicles gvwr. I contacted my tire manufacturer and got a load/inflation table for my tires and then weighed my truck with and without my Jayco. As I suspected, when running empty or even loaded my pressures were all too high. They did correspond with the max gvwr though.
Higher psi would give the opposite effect of a 'comfortable ride'. Also, wouldn't higher psi reduce your traction patch since you will be riding more on the center of the tire? Not to mention, wearing out the tires faster as well.
I run lower psi when empty and air up for towing, I am still below the 'vehicle manufactures suggest psi' even when towing, but in line (erring on the side of caution and leaving margin to add more weight) with the tire manufactures parameters.

Fuel mileage improves with increased tire pressure. It decreases rolling resistance and decreases heat buildup.
I've ran 80 psi rear and 65 psi front on the load range E tires on my tow vehicles for 10 years. Towing or not. I have had great tire life and no issues with uneven tire wear.

This is what I do. They dont put those ratings there just for fun.

Tire manufacturers build their tires to carry a specific weight at a specific pressure- Vehicle manufacturers post their recommendations to provide a more comfortable ride while carrying a specific weight- In the recent past, tire manufacturers got an undeserved black eye because vehicle manufacturers posted lower tire pressures to achieve a softer ride- The results were catastrophic- I always inflate all my tires to the maximum posted on the TIRE and endure what little discomfort is created- Incidentally, we have not had a tire failure in the last 10+ years of fulltiming- Of course, we have LT tires on both truck and trailer- JMHO- DD
