This is the best photo I ever saw that shows the "rivering wear" that will develop on a Goodyear G670 steer tire.

That looks exactly like the two steer tires I changed out in August last year . Mine were G670 goodyears. 2nd set (and last set) that did that to me.

I've never seen a tire wear like that. Is that caused by misalignment?

Don, that wear seems to be on Class A rv's using G670 Goodyears. Its a tire made for rv's. Some have used them for years with no problems. Alot, too many I think, have had this happen. Many of us have spoken to Goodyear reps, gotten alignments, checked the ride height etc and still it happens. Doesn't start right away but usually in the 2nd or 3 rd year and the fix that many have said is to overinflate and rotate the tires. Lotsa info on the web.

Looks just like my G670 Goodyear front tires before I replaced them with Michelin XZA-2 Energy.

AKA:
"Erosion Wear
What's Happening-
This condition happens most frequently in free rolling wheel positions and is typical of tires with a slow rate of wear. The longer a tire operates, the more likely it will develop this condition. This condition is not linked to any maintenance practices.

Probable Causes-
The cause of this condition is tread element movement laterally, but it is not seen as a major problem since the tread on the tire is wearing so slowly and the accumulated mileage on the tread will be so great.

Corrective Action-
Continue to run tire."

Have seen this condition on steer Class 8, over the road, and regional, tractor tires dating way back into the 1970s. And it is not limited to just Goodyear.

I have seen this before. Everyone I saw was on a spartan chassis and it needed an allignment. Even when a front end allignment was done it was not done to Spartan Specs which require that the ride height be adjusted to spec befor ethe allignment is attempted. There are not a lot of shops or people that know how to do it correctly.

Tires with decoupling groves just inside of the outside edges do not have this problem. You can just see it in this picture on the right edge. You would think GY would add this small grove to the G670 tires. Yes, I know they know more about it than I do, but I made sure my Firestone steer tires had this grove and while not enough miles yet (12K), I cannot see any uneven wear.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

Happens on any chassis, mine happened on a Roadmaster chassis. That particular picture is of a class 8 OTR tractor, that had all the specs checked and rechecked to make sure there was nothing out of whack. It was a Goodyear tire.

talked with goodyear and others and all the bull. had coach alignment done and redone because they said it was cause. said light weight of coaches on front axle; on a tire designed for an rv was the cause.
the design is faulty. put on michelins and several thousand miles later still fine.
