America's tire recommended tire pressures

I always adjust the tire pressure when I get home from a tire dealer. Many are clueless about tire pressure for a trailer anyway.

Carlisle tire warranty says to use max sidewall pressures. Check it out with Carlisle first.

This is a problem we get into when we severally over tire a trailer.

225/75R15D carlile are rated at 2830 @ 80 psi. Thats 11320 lbs @ full psi... You dont need that if your only at 7700 lbs.

Look on the Maxxis web site. They have a chart of recommended tire pressures by weight. The max pressure on the sidewall is not necessarily what you should run, despite many people on this forum believing otherwise. I would trust the tire manufacturer long before anything I read on these forums or was told by a tire dealer.

FWIW, I use D range Maxxis in that size on my fiver at 65 psi. My fiver is pretty much the same weight as yours. I have about 15000 mi on the tires with zero problems with much of the towing done at ambient temps over 100F. They are wearing nice and evenly all the way around. I would guess they're about half worn. Highly recommended.

I would definitely favor Maxxis over any Carlisle regardless of the size or weight range.

As always, YMMV...

You run the pressure for the weight rating... You do not need to run max most of the time.

Like car tires my truck states 50 psi with a weight rating of 2300 lbs. Thats 4600 lbs I can haul at max inflation...

LOL my axle rating is only 2700 lbs.. So I got the inflation chart for the tire and run them at 35 psi.

At 35 psi the tires are rated at 1400 lbs which is 2800 lbs.. Just above the axle ratings...

Mind you thats for two tires. If you have dual axle trailer the pressures may even be lower.

Hold out for the D rated Maxis. Nothing wrong with running an
load range E, it's being a Carlisle and THAT would be a concern to me.
