Uneven tire wear on light tire load

[firefighter_2000]

I have a set of Michelin LTX/MS2 tires with 42k miles. (LT265/70-17) The tires are wearing inevenly to the outside on both sides of the tires. Alignment is spot on checked at two different places. My vendor says this is an indication of too low of pressure in the tire. I run 50lbs in the rear & 60 in the front while having the light load button turned on. I can only find max pressure of 80psi on these tire spec sheets anywhere. This is close to ten sets of the LTX/MS tires I’ve had in my lifetime, all on 3/4 ton Dodge diesels, all run with lighter pressure in the rear for a smoother ride and I’ve never seen this wear.
Can anyone provide some insight?

I think the MS/2 has been discontinued, maybe due to poor quality? My set were not good at all.

It’s the Defender MS/2 now. I’ve had excellent results with all of the LTX series tires I’ve owned, averaging around 70-75k miles with great wear.

I think it is just the Defender LTX M/S now, no "2" designation if that matters....

The specs for toe in on our trucks call for too much toe in. This will cause the wear issues you are having. Have the alignment shop reduice the Toe in to the extreme low side and things will be better.

Yep. Discontinued do to sidewall failures. I've posted my personal experience with Michelin on this forum several times recently. Complete garbage being sold under a once quality manufacturer's name.

I have 12K on my Defenders and still look great. My set of MS2's installed at 200 miles on my Dually made it to 40K and they gave me $106 per tire back pro rated to buy any tire brand I wanted. I chose the Defenders as I have had AWESOME service from Michelins for well over 1/2 million miles of use.

firefighter it's easy to get proper pressure just scale the truck use the weight/inflation chart for your tires. For the fronts add 10# and rears 5#.

Specify front or rear, it makes a big difference.

Since the front is the usual culprit that is the typical result of too much toe in. Factory toe spec will cause that on certain tires, reduce to bare minimum of toe in and see if that helps.

I rotate every 5k, so they’re all worn the same. It’s not an alignment isssue because the tires are wearing on both the inside & out. It appears to be an underinflation issue, but I’m going by the tag on the truck for light load.

I have been running Ltx m/s since 99 never had a problem.
Since I Do not know which truck I will be using I keep all tires at 80 lbs.
A roving tire man keeps the liner tires topped up
If I Recall correctly I have 3 or 4 sets of the original Ltx/ms on and l am on my second set of version 2.
My gy RTs lasted 67,000 and the ATs lasted 44,000.

Look on the thuren website they have a different spec for these trucks for alignments, have it done to their specs and see how it goes

And if u happen to have factory air ride, there is a setting in ur settings on the nav system where u have to click "wheel alignment" before u get an alignment done

If your rotating the tires and they are wearing out on both sides definitely to low of air.
My 12 valve weiighs almost 1000 lbs my tire man( the roving one. Not where I buy the tires) Told me to h keep 80 in them because of the engine (front tires).
Your engine has to weigh more than my 12 valve.
I never have rotated tires my Dad was s true believer of keeping your best tires on the front. Yes the engine is up front but your back tires will wear out first because of they get the vehicle moving.
I never have lost control because of front tires being to worn to handle emergency manuvers ( their are a lot of a holes that drive down here.)

I understand the whole underinflation possibility. Is it possible that ram screwed up by putting the light load allowance in the truck. 60 pounds in the front and 45 in the rear makes the truck ride great... my first set of tires which were Firestone trans force AT’s didn’t have any problem In 48,000 miles. They were worn evenly all the way across.

So if you haven't changed your driving style and you have confirmed that your suspension, steering, and alignment are all good, what changed? The Michelin tires.

If you want to confirm that, buy something other than Michelin and report back in 40K. I think you and I both know what the results will be.

I've said it before and I will say it again, I purchased nothing but Michelin tires since at least 1998. My sets of LTX AS tires were amazing, lasting near 100K. My last 3 sets, 2 sets of LTX AT's and one set of MS were inferior to say the least and, as in the case if the last set of LTX MS, dangerous. We suffered a complete sidewall failure on that MS at highway speeds. The tires had only a few thousand miles on them and when I took it back to my tire dealer, they informed me that Michelin had a recall on the LTX MS and others due to sidewall failure. When I contacted Michelin, thet informed me that yes there was a recall, but I was out of luck because the 265/70/17 was one of the few sizes not included in their recall list. In no uncertain words I was told to go pound sand. A quality company would have requested to have that tire back for research purposes and/or offer to replace or help in replacing that tire. They offered neither and left me holding the bag.

After that experience, I will not waste my money on another Michelin product. I am happy that so many people still love their Michelin products and I wish them continued good luck. But that Michelin experience that you read so much about is not universal.

Go by the pressure recommendations on the tire not on the truck,see if this will resolve the issue.

 

[firefighter_2000]

Update. Michelin has decided that there is in fact something wrong with the tires and has given me 53% allowance towards new tires. I’m very satisfied. New tires are going on today!

 

[Cummins12V98]

WHY would anyone do that???? All that tells you is the MAX capacity at the MAX psi. Unless your weights dictate that much air you will be wearing out the tires in no time and have one HE!! of a rough ride.

 

[Cummins12V98]

These tires were shot at 40K Michelin gave me $106 per tire to spend on whatever brand I wanted. I chose the Defenders. At 12K I can see these tires will last a long time.

Last set MS2's at 40k first pic. Set on my 11 Dually at nearly 40k second pic.

That is plenty of air for a light/no load condition. Look at the inflation charts for your size. Weigh your truck. Easy.

Shared several posts on Instagram recently about tire inflation pressures.

I have been buying Michelin tires since I was 16 years old and I am 62 now and right after they came out with the ms2 tires I bought a set and didn’t get 10000 miles till they failed and they wouldn’t do anything about there problem so I stopped buying there tires after almost 50 years. If they don’t care I certainly do not.
