New Tires on TV

[Jim in Halifax]

Getting 4 new Michelin LT265/70R18 LTX-A/T2's on Monday.......
Front tires still have some tread but back tires are worn out.....

I think the recommended psi is 80 #'s.. I am towing a CC 29RE to FL after Christmas.

MY ?n is....Do you carry more air than the recommended pounds stamped on the tire in your back tires?

No way, over inflation will cause undue wear on the center of the tread and IMO is a dangerous thing to do.

Never over inflate, run the max psi on tire.

I know people will over inflate tires if they are hypermiling (less rolling resistance) in cars.

You have a window of tire pressure you can run.
First, look for the sticker in the door jam that will have a recommended tire pressure setting for the front and rear. Consider this your LOW pressure.
Second, look at the new tire's sidewall for the MAX cold psi. This pressure is your HIGH pressure.
Lastly, adjust the pressures keeping within your HIGH/LOW numbers until you're comfortable will the ride and performance.

I run those same tires. When towing, I inflate all four to 80psi. When not towing, I run with the GMC factory recommended pressures of 60psi front and 70psi rear. But quite frankly, it seems to me that 60psi all around would be just fine for me since when not towing, I never have anything in the back.

I run 60 psi in front and 80 psi in rear all the time, loader or empty. That's what it says on door jam

Please let us know how the tires are. I have the Firestone TransForce HT tires on my 2012 Ram 3500 Limited and absolutely hate them, worst tire they could put on a truck. They came on the truck new and with only 27,000 miles yes that's correct a 2012 with only 27,000 miles they are horrible in wet conditions and totally useless in snow even in four wheel drive. I'm getting rid of them before the snow flies and I'm also looking at the Michelin LTX A/T2's along with the BFG A/T KO2's. The BFG'S have a little better sidewall than the Michelin and are less expensive.

I have run the same brand and size of tires since June of 2013. But they are my winter tires for my truck, the fronts are aired to 60 PSI and the rear are aired to 50 PSI for a better ride than the 70 PSI that the factory wants when loaded. I rotated the tires every 5,000 miles and rebalance them when they are rotated. I usually put on between 6,000 and 10,000 miles from Nov1 to MAY 1, that's when I switch to my summer tires for towing.

The truck manufacturer recommended tire pressure is for a fully loaded truck. I adjust the pressure for my conditions. I run 55 psi front/rear when unloaded for improved ride quality and 60/70 psi front/rear when loaded or towing. Check with the tire manufacturer for a recommended tire pressure vs load chart to determine what is best for your application.

I have a 2014 Silverado 2500 LTZ/Ext/short Box......Truck came with these tires and I now have 52,000kms OR 32.3000+/- miles. There is some tread left to go and return from Fl after Christmas and maybe to mid summer......BUT...we are in snow country (none yet!!!) and will have some hwy travels prior to Christmas...Not worth taking a chance!!!!!!....PS With the Cdn $ it is cheaper to buy here at Costco than in US....I looked at the Firestones but most of my friends said "NO" the Mich are better!!!!

I just bought the same size Mishelin tires for my 2500 HD. $1138. For four tires.
I run 65 PSI in the front and 75 PSI in the rear when towing. This gives good stability and keeps the tires cool. I don't think you should ever put 80 psi in a cold tire, because when it warms up you will exceed the recommended 80 psi. max.
When driving the truck with no load in it, I lower the pressure somewhere between 40 and 45. This gives a much nicer ride. I did the same thing with my previous Michelin's. keeping a close eye on the tread wear, it was always uniform regardless.

[NMWildcat]

When towing I run the back at 80 and the front at 70. Without a load I run 65 all around. The door sticker says to run the front at 55 but it makes the handling way too mushy. And for the folks that still don't get the cold max psi on the tire: that is the max pressure COLD (before you warm them up traveling) which takes into account the pressure increase when they are warm from use.

[CaptnJohn]

65 front 80 rear 100% of the time.

[RJHuser]

The OP said he was getting 4 tires, the front are OK but the rear are worn out. This makes me think he has a dually.
On my 3500HD DRW Chevy recommends 70 psig front and 65 psig in the rears. This makes sense as the load on the rear is being carried by 4 tires, so the pressure should be lower as the load per tire is lower.

Edit:
Whoops, just looked at the OP's profile, he has a 2500. Forget the above.
