Tire pressure

[thebigfarmer]

I searched and couldn't find anything about this, but I was just wondering what I should be running for pressure because door says 35 but I feel like that's low. The tires I have say 65 max on them. They are road venture 265/75/16.

35 is what is recommended on my 17" Goodyears.

Thanks for the reply. Mine are at 40 were at 45. Not liking the way it rides now. Might go back to 45

if you over inflate them the center tread is going to wear out quicker and you will be running a homemade aquatread with tread on the sides and nothing in the middle, I would run no more than 40

I run 35 cold on 265/70/17 and that's what every tire center recommends me. Excellent tire wear and ride on the latitude tours, I cant stop recommending them!

 

The same can be said for my dads truck which has the same set up so 35 psi seems to be good for normal driving.

if you are running OEM tires that came with the truck, then the psi listed on the door is fine. if you are running aftermarket tires, then that number is no longer valid. best thing to do on OEM, non OEM tires is to get some kids sidewalk chalk and coat a section of your tread with it. then drive straight on a paved road, and see how the chalk has worn off. if worn in the center, deflate, outside, increase. do it until even across the tread, that will be the best psi..

"No longer valid" ?

 

I don't think so Tim lol

[kstruckcountry]

Eh I run 37. It depends on how much your particular truck weighs. And what you're using it for.

How to Check Tire Pressure

Tires have been known to lose up to 1psi (pounds per square inch) every month, so check all tires, including your spare, once a month (or before a long trip). It’s easy. Here’s how:

 

1. Purchase a trusted pressure gauge.
2. Check your tires “cold” – before you’ve driven or at least three hours after you’ve driven.
3. Insert pressure gauge into the valve stem on your tire. (The gauge will “pop” out and show a measured number. When you hear a “pssst” sound, that’s air escaping the tire. The escaping air shouldn’t affect pressure substantially, unless you hold down the air pressure gauge too long.)
4. Compare the measured psi to the psi found on the sticker inside the driver’s door of your vehicle or in owner’s manual. DO NOT compare to the psi on your tire’s sidewall.
5. If your psi is above the number, let air out until it matches. If below, add air (or have a Michelin retailer help you) until it reaches the proper number.

I have 265/75/17 on my truck. I've experimented with all kinds of different air pressures. For the best driveability & perfect wear, I run 37.5 in the front. 35 in the rear.

I've found 37.75 psi to be a better fit for my driving needs than 37.5

You really think a quarter of a psi makes a difference? These are trucks, not F1 cars.

[greg74]

Yeah, 35 psi is pretty much the recommended pressure for most LT tires. I just got new tires for my 99 and that's what they were all inflated to, 285/70/17's. Seems like a one-size-fits-all solution but that seems to be pretty much accepted to be the best.

[oldmann]

I would run 35 unless loaded. You must have LT tires that can handle a lot of weight. The originals are P-metric and do not allow for heavy loads.

Everyone has opinions, but I have yet to see anyone ask 1/2 ton, 3/4 ton? How is truck used? Haul heavy loads, trailers, etc often? I would take all that into consideration.
