HI THERE<br>I AM NEW TO YOUR SITE. I LIVE IN NEW BRUNSWICK CANADA.I OWN A 2001 4X4 DIESEL DUALLY, MY PROBLEM IS;I CAN,T KEEP THE FRONT TIRES FROM WEARING ON THE INSIDE AND OUTSIDE. I HAVE HAD 3 ALIGNMENTS DONE, I TRIED DIFFERENT AIR PRESSURES, I INSTALLED NEW MICHELIN TIRES<br>I AM A CONTRACTOR ,SO THE LOAD THAT I HAUL VARRIES ON MY TRUCK BUT IT DOESN'T SEEM TO MATTER IF I'M LOADED OR NOT .I HAVE ASKED ALOT OF PEOPLE AND THEIR ADVICE IS TO ROTATE THE TIRES ,BUT I WOULD HAVE TO DO IT EVERY WEEK TO HELP .I AM HOPING THAT SOMEONE ELSE HAS SOLVED THIS PROBLEM AND THEY WOULD KINDLY PASS ON ANY HELPFUL INFO ......THANKS IN ADVANCE<br><br>

 

Welcome.....What pressure are you currently running?<br>My dually gets 65-70 psi all the way around empty, and up to 80 psi runnin' heavy.<br><br>PS turn the caps lock off.

 

Thanks for the reply<br>I run 60 -65 in the new michelins. I have tried lowering the pressure and raising it . it doesn't seem to matter

 

If you're loading it down, you might try raising it to 70-80 psi.
Outside edge wear (both edges at the same time) usually indicates under-inflation.
Check your tire sidewalls for max inflation pressure.
If load range E tires should be around 80 max.

 

Mine wear the same as well they wear round the outside edges wear down and it has a round shape to the tire mine is from lowering the truck though maybe check the ball joints and camber?

 

I've got the same truck as you. I started running michelinxps allterrain load e. They have a stronger sidewall and that is what you need to have on a dually. Any time I run a weaker sidewall I have that problem. I also run the fronts 5# less than required. My loads go from 10k to 24k. Hope this helps

 

Usually wearing on both the inside and outside indicates underinflation, or fast cornering or both. Its possible you could have too much positive camber and too much toe out but the tires would be feathered and probably cupped.

 

There is a guy on one of the RV sites with a Ford F350 - he said that he takes his to a truck alignment shop - with his monster RV hooked up. He said that after doing it that way, his tires are wearing wonderfully and isn't having any problems. Something to consider. The site was iRV2.com.

 

<br>I do Alignments on these trucks &amp; can offer the following. Inside &amp; outside wear usaully is under inflation but lots of cornering can also have the same effect. Your alignment shops should have provided a printout showing your readings &amp; listing perfered settings. I have found on my own 2500 4x4 that pressure loss happens fairly quickly on the front tires, so I check it at least weekly &amp; I rotate the tires every 3,000 miles. It took some time to get the camber dialed in but everything is going fine now. Finally - loads will change the alignment &amp; it is perferable to align the truck with the standard load you carry. I even had customers get their truck aligned prior to a long trip with heavy load &amp; then re-aligned after returning &amp; removing the load.

 

I run 65 to 70 in the front and 60 to 65 in the rear year around loaded or not. I got 75000 out of the first set of Michelin tires and they are still flat across the tread. I rotate every 9000 to 10000 miles like the book says.
