What tire pressure when empty?
When I'm pulling my 15K horse trailer, I run the four back tires (Load Range E) at 80 psi, and the front tires at 65 psi. What would you recommend for tire pressure when not towing? Also, should you rotate the tires on a dually...I've heard you should just leave them in place on a dually.

Thanks!

I don't have a dually, but I run 60 in the back and 70 up front (LR E tires). I hear all you can do as far as rotation on those is change sides, if that's even worth it. I do know you have to make sure that the two tires don't touch when at the bottom, so if you want to lower the pressure a little, just make sure they're not touching.

I had a dually and the proper way to rotate the tires is to rotate the tires.... that means to dismount & remount them. Most people don't bother.
I normally run 65psi all around on my SRW

This is such a loaded question........... everyone has different taste and different ride preferences.... different handleing for different trucks..... but I think under load you will find that the 80 psi in the backs is a plenty, and could probably even work with 70 depending on road and temp. as far as the front, I have found that I like to keep them between 75 and 80 cold because of the weight of the truck and only a single wheel in front.... alot of it depends on the manufature of the tire aswell...... I would go with maxium stapped cold pressure on the tire and start adjusting from there depending on the wear patterns and ride... as far as rotation.... do them all..... if you look in your owners manual it will show you that pattern for rotation, the only difference is that i dont include the spare....
Hope this helps....

Man, what a pain. I think the owner's guide says to swap the fronts back & forth, but leave the rears alone. I kind of remember seeing it, but didn't pay it a whole bunch of attention. I hope you get it figured out to your satisfaction!

I dont think you will find anything set in stone as far as tire pressure,,, I like to watch my wear patterns and see what they need,,, if you learn to look at your tires you will start noticing how the tires wear,,, as far as rotation,,, let me just say this,,,,, front tires never never wear flat and smooth,,, hence the reason for moving them to the back and get them back to round and flat,,,, in the process bringing a back tire forward that is flat and round. dont forget to balance your tires aswell,,, between rotation and balancing you will get the most milage out of your tires,,, Oh and dont forget correct inflation pressure LOL sorry I know that is your oringinal question to begin with... You just have to find a happy medium somewhere,,, how often do you tow your trailer, is it mostly empty or full.... etc.....

Good subject. I'm torn between wanting high pressure to help with MPG and less pressure for even wear. I'm kind of surprised that empty at 80 PSI isn't that bad of a ride at all, but how will they wear?

Thanks guys for all the advice. I think I'll drop the rears to 65 and see how they wear. I'll probably do the rotation, since the place where I bought the tires included free rotation and balancing every 5000 miles. I'm looking into the proper rotation pattern, so I can make sure they do it right.
