Truck Tire Pressure

Having had my share of trailer blowouts years ago because I wanted smooth ride in the truck and trailer I did a lot of investigating and talked to Goodyear, Michelin and others - dealers and factories - and also on here. Blowouts came from under inflated / overheated tires.

Consensus among the tire people and most people on here was run at max on the tire. If there go over that when warmed up, they are built for it. And we run in some very warm temps.

So, mine are checked regularly (not every day) at ambient temp before I take off. Carry my own 120v / 140 max psi compressor (need 110psi for the trailer tires).

I also have air hitch and air ride on axles on the trailer; not on the truck. Check all that as well.

Knock on wood, no blowouts for 6-7 years.

BTW, you will most likely get all kinds of answers on here. I did before I went to the source.

If you talked to GY Tech Support they told you to follow what the RV or TV MFG says!

There is NO way GY told you to run MAX pressure unless the MFG says to.

I have talked to GY tech support, they said to follow what the MFG says unless you have changed load range like "E" to "G" for example. The they will tell you to weigh your tires and run what the weight/inflation chart says plus 5psi for the upsized tire.

With my 98 RAM 4X4 2500 I would get 120K on Michelin Tires and over 100K on BFG's because ran pressures based on load. 72psi all the time front, 40 solo rear and 80 loaded.

On my 15 RAM the door sticker says front 80, rears 65 and that is what I run loaded and run rears at 45 solo.

Did similar on the 11 RAM dually and had lots of even tread left at 40K.

In fact the tread on the rears was 1/32" thinner in the center at 45 solo/60 loaded.
