Tire pressure

[Bigstick]

What tire pressure are you all running, I have the less aggressive Michelin tires the big ones with the nice wheels on a 2001 4x4 quad cab. The front tires are cupping a little after 6500 miles. THanks

I have the original Michelin's on mine. Still smooth at 52,000. I run 65 front and 55 rear when I'm empty. Depending on how much I'm towing, I'll boost up the rear some.

I run 70 psi in all four of my michelins. I have little over 12,000 on them now and they look pretty good. I rotate every 5k.

 

[Alan Reagan]

I rotate every 5K also. Forgot about that.

 

[Hunter11]

I run 60psi front and 50psi rear empty. 10,000 miles so far with rotation at 5K and they still look new. I am with the other guys, I feel like rotating every 5K really helps with treadwear.

 

[Pit Bull]

I run 55 front and 40 rears. 235/85/16 Michelin M/S's. But I have 6 of them Tread wear is even.

What Alan said. Mine were wearing uneven and I kept changing pressure till I reached 65 front and 55 rear. Now have 45k (rotated regularly) and have even wear. There is still some tread left but they get real slick when it rains. Have some Cooper AT 315's ordered.

Empty, I run 55 front and 50 rear - just a little higher than the tire sheet suggests. I jack em all up when I tow. It's worked well for me so far (27k). If I run the front too high when empty, it doesn't steer as well.

I run 65 in frount & Back. I rotate every 10K. I currently have 23k on them and they not every worn, ok just a little bit.



I did notice if I take my cover off the back of the bed it Oo. .

45 in the front and 40 in the rear. Rotated every 6K miles. 16K miles on them and doing fine. If I haul something heavy, then I up the pressure accordingly.

dumb ?

How do you rotate tires on a dually?

Most people don't. If you want you can do the fronts side to side. What I do is when the fronts get worn half way I move them to the rear and replace the worst two rears with the fronts and buy two new fronts. That way I alway have good rubber on the ground and only have to buy two tires at a time and the wife won't yell at me for having six tires on my truck that cost a fortune to replace at one time. Works for me. I have Michelin 235/85/16's M/S and like them and want to stay with them. On the first round of changes you only have to buy one tire and use the new spare for the other front, then use the best left over rear as the spare. I did this at 40K miles and figure I will be at 65K miles when I have to buy two new tires and do the switch again. At 100K miles I should of purchased 5 new tires and still have two new ones on the front and four 1/2 worn ones on the rear and the wife will be happy. Mines a daily driver so the rears wear less than 1/2 as much as the fronts. If you tow a lot with a heavy 5th wheeler this scheme won't work as well. You can also do a search on tire rotation and you will see that most of the guys with 3500's don't rotate. Hope this helps

60 front 55 rear, wearing even, rotated once, 29000 miles. I should be able to get another 25000 miles out of them, If I can keep my foot out of it. Oo.

As far as rotating tires on a 3500... . see page 144 in the owner's manual (2001) for the DC diagram. I have been doing this every 5K miles or so, and tires look nearly new with about 16K miles on them.





By the way, 65 psig front, 45 psig back unloaded seems best for my truck. I liked the idea in the earlier post about measuring tire temperture differences across the tread. Thats how real tire technicians figure out pressure (and alignment) on race cars.

I run 50 front and rear on my Michelin LTV's, except when towing the 5th wheel and then I up to 80 front and rear. 84,000 miles on them and will change them at 90,000. Unbelievable--made a real fan of Michelins out of me.
