Maxxis failure

[pakuma]

I am very disappointed in the Maxxis tires I got for my 5er.
I went to pack the wheel bearings and discovered 3 tires out of round, upon further inspection they were delaminating.
I am leaving soon and I am putting a set of Carlisle tires on.
I have attached a picture of one of the tires all three looked like this. I initially thought that I had an alignment issue or bent axle not so.
They are just less than 4 years old and probably around 5,000 miles.

That's the pits! I hate it for you.

For others input; I was reading on another forum a few days ago that the reports of Maxxis failures are growing. Anyone had any experiences with that?

It looks like something is definitely out of alignment, the inside edge shows almost no wear but the tread blocks on the outside edge have been worn away.

I thought it was out of alignment, but I used old school and measure it, it was almost completely in alignment. The left side is 1/2" closer to center than the right.
thank you though

Something's not aligned or too much camber for a tire to wear like that IMHO

That doesn't read like it's "in alignment" to me. Are you saying the left side axles are 1/2 inch closer together? If the axles are straight and parallel then it should create a perfect rectangle with each of the two opposing sides having equal distances.

looking at the feathering and scuffing on that tire there is something amiss with the axle alignment.... a good trailer repair shop will be able to properly measure and repair your issue

Pakuma, I don't want to jump in and defend the Maxxis. They have a great reputation, but there are always exceptions. But not three with the same problem as a general rule. I've read every post on this thread and I fully agree with all, especially Chuck's advice of having it aligned.
Your RV is not in good alignment and your new rubber will simply follow suit.

While i would agree about the alignment if this was the only tire, but 3 out of the 4 tires on the coach had this appearance and sever tread separation; the fourth was getting there. I agree with having the alignment checked, i don't believe that alignment was the cause.
The axles have no measurable tow out or toe in.
The axles are square to each other.
Checking from the front axle tires centerline to the kingpin center the left side if forward 1/2".

If those Maxxis tires do not have a speed letter or speed rating molded onto the tire sidewall, they are 65 MPH tires.

When tire treads start to separate from the carcass, they will grow. Here is a picture of two identical brand and designated sized tires. The taller one would have had a complete tread separation had it not been found before it could fail.

The Maxxis' had a speed rating of 70 MPH.
When I am towing I am in no hurry and I keep my speed at 65 or less.
Even though the Carlisle's are rated to 80 I have no intention to change,besides I am on holiday and am in no rush.

Personally, I would go with the new Goodyear Endurance over the Carlisle's. Chris

Can you expand on why a little? I know there's been some here who would like to see some more "mileage" on these new Goodyears and how they hold up compared to a tried and true Carlisle. I've been planning on changing out the OEM tires with a better set. I've been on the fence and I'm taking in all that I can from both sides, love to hear your input.

There is no speed letter for 70 MPH. Did the tire actually have, "MAX SPEEC 70 MPH printed on it?

Again, I reiterate, official tire speed ratings can only become official if displayed on the tire with a speed letter or a value molded on the tire sidewall.

ST tires without having an official speed rating on their sidewalls default to the TRA standard of 65 MPH.

Here are a couple of pictures showing the two official methods of depicting tire speed ratings on a tire sidewall. The first shows a tire service description followed by a letter L. The "L" is the speed letter for 75 MPH. The second picture shows a tire with an actual tire speed rating molded onto the tire sidewall.

The GY Endurance trailer tires have a couple of features most other ST tires do not have. First is a nylon belt overlay and the second is sidewall scuff guard inserts.

ST tires are not mileage tires, they are age-out tires. Years ago the estimated mileage for ST tires was 3000 - 10000 miles or 3 - 5 years of service. The evolution of ST tire manufacturing and materials increased rapidly causing those figures to rise just as rapidly. However, there are no solid figures for mileage use or age-out time. The individual tire warranty package may give you a clue.

Understood. Thanks for the details.

Goodyear put a lot of work into the Endurance, and has a vested interest in making sure people are happy with it. Also GY is the about the only tire manufacture that will pay for trailer damage if you go about it correctly. 1. Saving the failed tire. 2. Being polite but firm. 3. Not accepting only your insurance deductible.

I wonder how this differs with their Marathon tire? Hmmmm? And they built it for years knowing how bad it was...

The fact that 3 of the 4 tires have an abnormal tread wear and the bolded statement tell me that something is wrong. The axles can be parallel to one another but if it isn't square to the pin/frame then it's going to "crab" going down the road resulting in the tires scuffing and premature wear as the force on the tires will not be parallel to the tread.

I hope you get the alignment checked before ruining that new set of tires.

Lets start with the ST235/80R16. The Marathon weighed 34 pounds and the Endurance in that size weighs 39 pounds and has a service description of 123N (87MPH), where as the Marathon did not have a service description and was a 65MPH tire. We bought a 25 foot Terry 5th wheel in early 1997 and it had Marathon tires, and the originals were still on it when we traded it in for a new 5th wheel in June of 2004.

Carlisle built some of the worst trailer tires for years, and now people recommend them. However since people started recommending them, they have had to upgrade/change them at least twice.

I am one of the few that has had an issue with a Endurance. It was a road hazard. I did not pay the extra for road hazard coverage. Goodyear however as a gesture of good will pay for one half of the cost of a new tire. How many other tire companies do you thing would have done that.
