Need help with air pressure in tires

i just replaced my tires on my z71. it had passenger tires on it, and held 35 psi. the trk called for LT tires so thats what i went back with, and the LTs calls for 50, i noticed a lil difference in ride but not much.

Mine Michelin LT tires had a maximum rating of 80psi. Should I be putting 80psi on then or put on what the manufacturer call for

Are you pulling with your truck if so i reccomnd 50psi but for just regular road travel Id but it at 42 psi to 45 psi anything under 40 psi tend to wear out your tires faster but may not offect the drive.

Actually, we bought it in order to be able to pull a horse trailer. However, most of the time it will be used without a trailer and only as transportation. That being the case what should be the inflation?

In short, if the manufacturer says to run 50 lbs, then run 50 lbs. It doesn't matter what the truck rides like - do what the tire manufacturer says to do. They are EXPERTS in their field. You bought a truck, thus it may ride like a truck.

is your last name Lasater? If so, are you related to a Jeff Lasater in southern Ohio?

Just curious.

if the max psi is 50 it is cold pressure and you should allow a 5lbs slack for expansion meaning 50 psi you put 45 psi to allow the tire to expand if you over inflate it youll we them out faster.as far as for what you have 45psi is fine for the road when pulling check to see if yur tires sag with the trailor on it if they do bump the up to 50 psi.this is allowing your tires proper seating on the road and less chance of wearig out.

I suggest you get ahold of someone at Michelin and see if you hear that one a second time. I find that awfully hard to believe!

sez:

If they are run close to the maximum rated load, then yes, go with the maximum rated pressure. If running lighter, less pressure is fine.

My LT's (Load Range "E") are spec'ed at 80 psi with max load but I run them at 38-40 psi when running light.

Finally, a correct response.

thanks, I was just wondering.
