Michelin ltx at2 right psi?

whats is the right psi. I heard anything from 35 psi all the way up to 45 psi. Currently I’m at 40 psi all around. What do you guys think?

 

Depends on the size and the load range of that particular tire. Care to share more info about your tires?

 

They are 275/65/18 tires. Stock 19 cm

 

32psi cold is good across the board for a standard tire for city driving.

 

The door jam sticker will tell you the correct psi.

 

Do you drive a lot of winding roads? Stop and go city driving? I find that the door jamb psi is geared for mostly straight easy driving. If you are braking or turning a lot ill bet higher in the front will feel far better. I always run higher in all of my cars and the tires wear more evenly

 

Door jamb says 30 front and 33 rear which seems very low?!!

 

That’s not low. And the manufacturer determines that for a good reason.

I also always run my tires a little higher, 35psi

 

You probably want to be 38 to 40. The best way to determine proper inflation is to do a chalk test. Put chalk test in the search bar for a thread on how to do it. The poundage on the sticker in the door jamb is more for comfort and not necessarily the best poundage for tire performance and longevity or mileage.

Look on the side of the tire. It has a max psi. Mine are 51 max. I usually run 44 psi and haven't had any problems. Even wear, lots of tread left, and got 32k on them.

Often the door stickers are lower because manufacturers like to make a softer ride. But duh it's a half ton truck. Gonna lose my p rated oem tires when they wear out and get some LT truck tires.

 

I like 32 to 35 psi. 40 psig would make the tire and the ride harder than woodpecker lips.

 

Are your tires stock tires? For stock tires, I would run what is given in the manual. I have e-rated tires (with maximum psi of 80) and I run them around 45.

edit: I forgot you mentioned your tire in the title. My bad. I would definitely run higher than the indicated psi on the doorjamb. When I run mine at 30-35, they feel spongy. You could always try the chalk test.
