This is an old thread but it seems that the Marathon saga continues. On a recent cross-country trip in my 2012 Monty 3150RL I was setting up came outside Teton NP when I noticed abnormal wear on one of my Marathons. I removed it and it was a clear case of tread separation. I was so happy that I caught it before it came apart and caused damage to my rig. Pulled the Marathon spare from underneath and had it mounted on a street rim. Had to buy a Maxxis so that I had a spare. Oh well - another tire from China. Anyway, after getting home safely I inspected the other three trailer tires and found one more that seems to be headed to tread separation. Wanting to upgrade to G614s but am concerned about my 16x6 rims. They are properly rated for load and the 110 psi for the G614s but the Goodyear web site says the only approved rim width is 6.5". Has anyone put G614s on 6.0" rims? Did you have any problems? Thanks.

According to the profile for the OP his unit is a 2007 - 3400RL, that is right up there with the heaviest of the Montana's, if those tires were original they are now at the very least 6 years old, they may not have seen a lot of miles, but I believe the weight of these heavy units sitting in the same spot on a tire over prolonged periods will affect the life of the tires as was mentioned by someone else. It is entirely possible those tires were manufactured 7 years ago.
How do you judge the life expectancy of a tire when there are few miles but they have been through a good many years of sun and other conditions.
Since the OP did not provide the make of tire, everyone assumes the tires were made in China because they failed, if in fact they are original tires I don't think the country of origin has much to do with it.
The important thing is not a lot of damage was done and everyone was safe and it did not involve others on the road.
The sad reality is that fewer and fewer tires are being made in the USA and Canada, that does not necessarily mean they are no good. We have been sold tools with our Montana's that were not sufficient for the job they needed to do. Pay close attention to the weight of your unit and upgrade to a load range G tire on these heavy units.

Well that's a familiar site to a lot of us, glad the damage wasn't too extensive, looks like you had some room to pull off the road anyway and that's a plus. We blew 2 on the same side as well and the tire dude said the one's on the other side were starting to separate as well so we replaced all 4 plus I bought an extra wheel and spare just in case, oh yeah and a new TPMS as well, not sure how much warning they would have given due to the nature of the failure but I'm glad to have it now.

Basically wherever the tire was manufactured it should be replaced after 5-7 years.
