As long as they just sat, the tires don't care. To answer your question I don't know! It was a Fire Truck, maybe some of the guy's painting the sidewalls black (old style tire black) had to do something with it? Maybe it was the weather? Maybe it was old age because it sat for 10 years doesn't mean the tires were 10 years old they could have been older? Maybe it was sitting on concrete for ten years? If I said they cracked they cracked!

I have no doubt they cracked. Just saying that sitting there didn't make them crack sooner.

I am on my 2nd set of G 670s and have had no problems.
In all the years I have been on this board and read about all kind of tire problems from blow outs to rivering to leaking to coming apart and so on, not one time, not one has anybody ever said it was there fault or my coach had an issue. Not one! You can't keep blaming your problems on someone else all the time. Not saying some are not legit, but 90% of tire blowouts come from under inflation . This so called riveting has been claimed for over 2 years now and I assure you if there were a problem, Goodyear would have corrected it in it's manf, by now.

I have between 28K and 30K miles on my G670's and no rivering whatsoever. I think a lot of people have or develop some sort of problem and since its been documented that GY670's CAN and DO river...then their trouble is also rivering....in their minds at least.
Totally wearing away the outer most rib and the inner most rib on a tire IS NOT a sign of rivering at all. Also having decent wear on any tire for some period of time and then take a trip to Alaska and lose both inner and outer ribs totally..isnt a tire problem..its a mechanical problem of some sort..?? And Flat spotting in many cases is an indicator of shock absorbers that are SHOT.
My 670's have done me fine and would I buy them again? Dont know...I'll wait till tire time comes to make that decision.

Tires: G670 RV 245/70R19.5 on 2008 Itasca 30’
All have premature tread wear on outer edge. Always been inflated over the GY chart for the measured weight on them.
Previous to this wear, 4 were replaced new due to vibration issues.
I'm sure some of these tires, probably the majority, are fine. But when a lot of them are not, then it's something important to know.
10 out of the 10 new G670's cost me lots of time, aggravation and money.
Replaced with US made Bridgestone's.
FYI, directly from Goodyear’s website: "River wear (sometimes called errosion wear) is common in situations where steer axle loads are light, turning is infrequent (mainly straight, Interstate routes) and the wear rate is slow. Fortunately, this type of wear condition is noting to worry about from a tire performance standpoint
My edge wear was extreme, and definitely something to worry about.

Sounds like the problem could be minimized by rotating the tires every 6000 miles or according to the chassis manufacturers recommendations. This is the same reason why people rotate their tires on their toads. The steer axle wears more than the rear. Rotate your tires to even out the wear on all coach/toad tires or just accept the fact that your steer tires WILL wear out before the rears.

Lots of misinformation. rotating tires on a MH with duals and a tag is not a great idea. Not all MH's have that rivering problem . If you have Toyo, Continental Hanccok,etc. there has never been a rivering complaint. Like the previous poster all my pressures are way over what is needed yet the tires still failed. It is only the G670's that have this problem. I spoke with one owner who replaced the 670's with GY Marathon. End of problem! Remember this is a tire that was built exclisively for MH's. The engineers should have realized that without a decoupling groove and a better tire compound the tires would fail. Again I will state: If you are in the market for tires or are looking at a MH with G670's buyer beware! I might also add that I have never heard of this problem with sizes other than 22.5.

I'll bet that your chassis owner's manual would disagree with you about tire rotation, but it's your coach, not mine. I know that the tire manufacturers all mention tire rotation and balance as part of the tire maintenance procedure to even out wear, but what do they know.

Yes, mine were 19.5
My post stated all (6) tires had their outer treads excessively worn.
How could rotating change this?

May as well jump in Mo...have Josam alignment, always check pressures, never hit a curb and the GY's were crap. They run fine on the back. And yeah they were all rotated, until I ran out of good ones to put on the front. Now running the FS400 315's on the front like Ivylog...zero problems!!. The six rears are ready for replacement and will NOT be GY's no matter what! The Hummer will get new skins soon and they will not be GY's either.
Like 'em or hate 'em..but vote with your $$$. Just one old guys thoughts.
