Tire pressure??

ace3166 · November 16, 2003

Hi,

Was wondering what tire pressure I should be running for best wear,ride and mileage for normal everyday driving. I have 265/75/16, load range "E" tires. All it says on tires is max. pressure 80 psi cold. Any tire experts out there??

my yukon has a sticker on the driver side door that lists the cold psi for all the tires. you might want to check there. but i think this is for the tire that comes stock with the car and don't know if it applies to other tires.

What kind of vehicle?

On my HD2500 I run 50 psi in my 265/75/16 Michelin LTX M/S load range "E".

I was confused on this issue also. The sticker on the inside of my driver's door says that the tire pressure should be 35 psi cold for the stock tires, 265-75-16, I think. I now have 285-50-20 tires. The tires have 40 psi max printed on the sidewall. So I didn't know what to keep them at. So I called the experts at TireRack.com. I explained my scenario and, to my surprise, that tire expert explained that I should follow the manufacturer's recommendation IRREGARDLESS of what size tire I have. I said that this didn't make sense to me. He said that I should do what the sticker says because that is what has been tested as the best tire pressure for my vehicle (03 Yukon). He said that tire size didn't matter because it's still the same volume of air inside the tire. He said that you should only run the max pressure that is printed on the tire sidewall when you are carrying a full load. For everyday driving around town, the tires should be set at factory pressure.

So, I'm running 35 psi, but I still have a little doubt in the back of my head.

Any tire experts here?

Tire rack guy is absolutely correct! The tire sidewall rating for max pressure is so you know if you can use that tire on a vehicle that requires that pressure. Stick to what the label on the door frame says.

I've been running 50 psi in the BFG All-Terrains with good results.

45psi on all four when empty. BFG AT KO's 305.75.16's

One quick note here...

Even if you have a load range "E" tire which is rated for 80 psi on your 1/2 ton aluminum wheel, I think the wheel is only rated around 60 psi max. (It should be marked on the inside of the wheel somewhere)

Therefore don't exceed the psi rating of your wheel...
