Tire Wear pattern odd-long

[Jobert]

I am experiencing an odd tire wear pattern on a MM with ifs 1370 front axle and G670 Goodyears. The left front is wearing on the outer tread bar at an angle in about 3/4" then steps up about 1/16" and moves into the inner edge of the tread. This pattern runs all the way around the tire with no cupping or variation. But it gets better, on the right outside tread, the same thing is happening but only about 1/2 way around the tire.
Now I have already made my trip to Spartan one year ago for the ball joint replacement upper and lower, had ride height set, required alignment, tires balanced, and they had about 3000 miles on them at the time. I have put 7000 miles on them since and this wear is showing, started noticing it about this spring on the way home.
Has anyone else experienced anything odd like this. I weighed the 4 corners and checked ride heights, they are fine and inflation has always been good and should not be an issue. I did get conflicting front ride height info from 2 different sources in CS at Spartan. One is the shock length at 16 1/8 on each side, the other is bottom frame to ground minus center of spindle to ground at 6.06. The problem with these 2 methods is that they do not give the same info. My shock length was correct but the other method gave an inch+ to high at 7.125. my chassis has 1 valve in front.
I am open to any suggestions and thanks in advance. Bert

I think I have read that the Goodyear RV tires are having problems on the front of some MH. It is not called feathering, but rivering I believe. Search this tire on the forum for more info.

Good Luck!

That has been found on solid axles, but not on IFS as far as I could find. I had that on my last coach with the solid axle. I will search some more though. I did wonder if it was a variation of that. Thanks Bert

The rivering seems to be a problem with the GoodYears no matter whether IFS or beam axle.

Had the outer 1" wear on one front tire (Michliens) all the way around the tire. Spartan did all the front end stuff and it still wore. The solution was to move the front tires to the drive axles and put the "broken in" drive tires on the front. Solved the problem.

It is Riveting. Have it on my Monaco. Goodyear will not do anything about. Took it to a truck dealer and they said Goodyear will pay to replace tires. Mine seems to be disapearing.

If you do a research on rivering. You will find the OP doesn't have that problem.
Rivering will ware both outside treads the same.

It doesn't river on one side of the tire only like the OP is.

I have G670's and all 6 show a little of the so called rivering. A little wear on all the outside treads. The way my over 6 year old tires are wearing. They may be down to the tread replace line in another 8-10 years.

Went to Spartan today, they checked the whole front end over. The front and rear ride height were fine, toe was fine and their conclusion was the same as the Skipper, it was a tire thing. I will take it home and have the two fronts moved to a set of duals and have the set of duals moved to the front. They all will have to be dismounted and remounted and balanced because of the aluminum wheels. The Good Year dealer, with no information about previous work performed, came to the same conclusion, so that is what I will do. Will get the balancing beads ordered for the front and get it done, hope that is indeed the answer. Thanks for the help and input. Happy Trails Bert

I think I have a similar problem with just my front passenger tire. It is a Yokohoma and the outside tread bar is wearing significantly. The outer tread on this tire has worn about 3/8 inch on the outer edge and the inner edge is almost even with the next inner tread which shows almost no wear, or is equal to the tread depth on the other five tires. The tires have about 15,000 miles on them. The rig drives great with no pulling or wander. Ball joints tie rod ends, suspension height, and alignment were all checked. No problems were found, however, technicians believe my brake clunking on right wheel is related but they can not find a problem. Next week the rig goes back in to have the tire swapped to the rear.

Got the tires moved around today, swapped left front to left rear outer, right front to left rear inner and kept rotation direction the same, spin balance on rears and ceramic balancing beads on fronts, seemed to drive out well, although it drove well before with a slight balance vibration maybe. Will be awhile before we see any wear on fronts so do not know if that will be the final answer or not. had to dismount and remount all because of aluminum wheels but if it works, that will be OK also. Thanks for all the suggestions and advise. Happy Trails Bert

Did anyone check alignment of Duals. My front tire wear pattern was caused by duals being mis aligned.

I finally saw a couple of Michlien 315/80/22.5 on the front of an '06 Newmar Essex and it looks like someone cut out about a 1/2" grove off of the tread on both sides. Weird. IFS 1600lb.

As far as alignment, when I had the ball joint replacement last year, they did do a four wheel alignment. Shocks seem to be good, ride is good without excessive rebound. Time will tell if the problem returns, some say it will some say it will not until new tires are put on the front again, and then maybe. The truck ire person said he has seen the same thing a few times on trucks used locally that he does all the work on, and Spartan echoed the same thing, so we shall see, it is done for now though. Thanks for all the help and suggestions. Happy Trails Bert
