That is definitely rivering and a known issue for the Goodyear G670 tires. I won't buy Goodyears anymore.

Do the Michelin's still crack on the sidewall or is that an old issue? I two prices from local shops and the Michelin is actually less expensive than replacing with another g670 that are on there.

Rivering is caused by going straight. High speeds, little turning, same conditions all the time, little variations. Sound like most RVs? Had some Hancook's do it in the front, both outside edges. Did a lot of research to find this answer, thought is was mechanical.

My fronts got so bad by 20,000 miles I replaced them. At 30,000 the rears are doing it now.

Yeah, on my last coach, had to replace the front G670's at a little less than 30K miles due to rivering. The rears were fine.
I've heard most people take the fronts when they start rivering and put them on the inside dual position.
This coach has Michelins and I try to take much better care of them. Always covered and use 303 on them every time I wash the coach.

Still an issue on many Michelin's. I'm very happy with my new Bridgestone Ecopia R268 tires. Better ride than the Goodyear G670's and much less expensive

I would guess that the dealer or previous owner was wrong and that tire was previously on the front. It's definitely "rivering"....after having the issue on two sets of tires and Goodyear denying any issues with the G670's, I have elected to never give Goodyear another dime of my money.
Here is a good photo of what it does.

I believe that is called cupping. If it is a dually the tires may have been set to one side in other words not Square causing it to run to the edge not true to the road but it is under an alignment issue

If you get the tires up off the ground and set a hammer to the edge of the tire a quarter inch or less away from the tire at the bottom then spin the tire it should clear the hammer all way around

That thought occurred to me while reading the first page. That picture does not fit the normal "rivering" pictures found on the internet. Tire mounting is an important issue, improper or lackadaisical mounting may cause this problem, and/or extremely out-of-balance condition.

If it has always been on the back have the track bar bushings checked. If that was on the front there would be no way the coach didn't vibrate and pull. However a track bar issue will destroy the tire by scrubbing it forward and aft as you drive.

The dealer is going to replace before purchase (with some negotiation). I am going to have them replace the fronts and move one of the current Goodyears back to replace that tire. They gave me the option of a pair Goodyears to match the rears or go with Michelin. My gut tells me to go to michelin, but I am not sure if that is my personal bias since I run Michelin on my cars.
If the Choice was Michelin or Goodyear to match the rears ...would you go Michelin on the steers?
