Rear tire pressure

[micktaylor]

When towing a fifth wheel trailer should I increase my rear tire pressure and if so by how much? My 5th wheel is a 2007 Cougar model 276RLS towed with a 2012 Ford F150 Eco-boost. Thanks

open your drivers door on the door jam there should be a sticker that says tire pressure and loading information. inflate to those pressures I put a picture of mine so you can see what it looks like. don't use my pressures on my sticker I have a 350 but your sticker should look the same just different numbers

You might want to search this question as their are many comments on what others do for tire pressure settings when TV is loaded. The sticker on the door gives the best setting for tire pressure for general usage, fuel and occupants. If you look on the side of the tire it will give you the max PSI and weight the tire is designed to carry. When loading the truck for towing or carry heavy weight I have been advised by truck dealer and RV dealer to run the rear tire up to maximum PSI and if the front of the truck has increased weight on the tires to put them up as well. Low PSI when truck is carrying weight causes heat and can lead to tire failure.

x2 on the max air. The door sticker is generally a pressure that takes into account normal load and comfort - except on my new Dodge 2500. Rear on the sticker is 80psi - the max for the rear tires.

The max pressure on the side of the tire is recommended for "max" loading of the tire - which you will probably be close to with the weight of the trailer hitch. With a loaded trailer and truck you probably want to be somewhere near the max pressure on the truck AND trailer tires to ward off any unexpected surprises.

Your owners manual will tell you what is recommended by it's manufacturer.

Many thanks for the replies to my question. Will go for max pressure as listed on tire wall. Mick ex Royal Navy.

I personally started with max air pressure for the tire, then watched the wear pattern. If I was getting a lot of center wear, I drop the pressure a bit. do the same with the front tires. The best thing for your tires for wear and for you for control is proper pressure for the load that is on them. Full and even contact across the entire tread pattern is the best for both
