Truck Tire Air Pressure

[Juiceman]

I had a set of load range E tires on a half ton truck. Kept them at 43psi. Had 80,000 on the tires when I traded the truck in. Discount tire recommended 43 for my set up and it worked great for me!

My 2500 Ram will give me a low tire warning if I run them below 60, so I run 60 unless I have a load then I bump them up to 75

Read the tag. It's usually pretty accurate

His is a half ton. On tires that are rated for that much max pressure, they’re going to ride rougher by nature. Start talking about much over about 50, that truck’s going to bounce all over the place without a load on it.

OP, everyday driving, stay under 50 PSI. Low to middle 40’s will work better for you in most cases. Air up/down as needed due to purpose.

Keep adjusting pressure till you get even wear.

I have a Toyota tundra crewmax. I’m running 35’s load range E nittos. First set after original tires were Nitto ridge grapplers. Ran them at 35psi. Got 85k out of them. I could have gone more. I have recon grapplers now with 35k on them and they will easily go to the 80k range as well. I run them at 35 too. I took sidewalk chalk and coated my first set and inflated them to 50psi and drove them about 1/4 mile in a straight line. In the beginning at 50psi there was only roughy 8” of the 12” tire with chalk missing in the middle. I kept deflating 5 pounds at a time and retested each time until all the chalk wore off the full width of tread.

Try the chalk test yourself and see.

Ran my wrangler 4 door with load range E tires with 35 psi and got 120k out of them. Never towed more than a trailer with a side by side or a boat. Discount put 45 in them and it was wearing down the middle I let some air out and found where they wore the best. And makes for a way smoother ride.

The door doesn’t matter anymore.
I had a Silverado. Door said 35. New tires shook the truck. Emailed bfg. They told me it needed to be 55.

Fixed it. No more shake.

Reach out to company. Different tires different specs

X2 for best ride and handling. Add air when loaded

It doesn’t matter what your tires are rated for if the rims pressure doesn’t match. If running stock wheels, run tires at factory specs. If your rims do match and you are basically running 3/4-1-ton rated tires on a 1/2-ton run them where the tread wears even. It’s still going to beat you up

I run 70, don’t like to add air or take out for anything

I run load range E tires on my half ton trucks. I run 40 psi. Rides like crap once you get above 45-50 psi. 10 ply tires are awesome!!!

40-45 for me. E rated on a tundra.
