Dually tire question.

[kennethwooster]

I have a 2014 F350 DRW. I probably have about 16,000 miles on original BFG. I was thinking about rotation the tires, and while looking real close I noticed both out side duels were way down compared to the inside dual. I know I must rotate, but want to slow up this excess ware. I figure I probably need to lower the tire pressure on the out side dull. Just wondered what some of you are doing to keep the wear even. I run tire pressure at Ford's recommendations which is 65 on the rear.

The 2 wheels are bolted together. One wheel/tire cannot travel farther then the other one without breaking the bolts.

I think that what happens is that one tire must slip a tiny bit in turns. And they are rubber so they can absorb a little slip too. Kind of like the way Funny Car tires look just as all that power is applied, only on a smaller scale.

The outside DRW tire will always wear faster because when you turn corners it has to spin just a little more than the inner tire.

Both tires/wheels on a dually are bolted together. They cannot rotate at different speeds.

Take and draw two circles one inside of the other, the outer circle (outside tire) has to travel further than the inner tire.

Excuse my newbie question but is there any tricks on how best way to line up the inner tire valve stem to make them easily accessible from the outside?

There's really no way to make the OEM short valve stems more accessible. You either will need to replace them with longer versions or add extensions.

Extensions have developed a reputation for losing air pressure. What I found out was that you only want to add extensions to metal OEM valve stems and you also want to make sure the extensions are good and tight and then keep them that way. Be aware of the effect of centrifugal force on the extensions. Use the shortest (metal) ones that will work.

It helps to have good gauges too. I have a Milton S-986. Milton does not make cheap stuff but Amazon is your friend.

I full time and have a 2013 F350 dually. The original Generals have about 44k on them. The last time I had them measured, the rear inners had a little less wear then the outers. I keep all tires inflated to Ford specs. I just replaced the fronts and will replace the rears before I start traveling this spring. They might make it to 50k if I kept them but why push it when they will be marginal in the rain ? Costco here I come.

I do rotate the fronts but not the rears. I don't believe it's cost effective - the inners are on steel rims so they would need to be dismounted, then remounted - at additional cost.

Free rotate and balance with my tires also. They do a triangle rotation. I'll have em done every 7500.

[Cummins12V98]

Just rotate the fronts side to side.

This is a great discussion and have been undecided on tire rotation on my new Dually truck. I have Alcoa wheels too and assume steel inners. Have 11,400 miles now. Read so many posts of owners that do rotate and many others that do not. Have free rotation at dealer where I bought it. Got to check but assume balance is extra? Still undecided...

My local tire dealer told me he cold rotate for about 125.00. Thats breaking down each tire mounting on proper wheel, to keep chrome out. Would also balance each wheel and tire. I will probably do that before RV season hits. By the way Ford wanted close to 500.00 for the same rotation. I may try running 5 lbs less air in outside tires. Has this procedure worked for any of you?

And this is why most don't rotate dually tires.
The rotations will cost far more than any additional treadwear you gain.

I just run them till they need replacing. Usually its the fronts or the rears. So the bill isn't too bad.

So my tire guy does free rotations. I have been able to 80K out 2 sets of Michelin's. I'm on my 3rd set now.
I rotate at 10K or so.
If I can get 80K out of a set of tires . I'm willing to endure the hassle of rotating.
Dog you bring up a good point. How much extra wear does one gain by rotating?

Good discussion and thanks for the help.

Unless you do your own dismounting and balancing with those expensive shinny wheels, it's cheaper to just leave them where they are.

I only rotate the fronts and let the rears stay where they are, on Fords you have to dismount the rears because of the aluminum wheels so it's not worth it.

In winter times I run 65 psi in rear and 55psi in front.Summer time 80 psi in rears and 70 in front.Rotate every 6K miles side to side.Tire shop told me to dismount tires every 18k miles.16 dollars each tire.My nitto G2 tires are wearing great no issues.
