Tread separation? My guess is it will be oval instead of round when you unmounted it. I had same thing on my last RV. Caught it while checking tires after another blew out.

That tire is shot. Looks like some kind of tread separation. I would NOT use that tire!!! Unless you want to replace a blowout on the road and repair your TT's bodywork.

Just my opinion though.

You have exactly the same issue as I had with the MaraBombs on my previous SOB (Montana). My MaraBombs would start out on a trip looking like the one on the right ... after about 50 miles they would swell up and start looking like the old Model T ballon tires as yours does on the left. The belts failed in mine I was told. After they sat over night, they would go back to looking semi normal. There has been issue after issue with MaraBombs on other forums on the heavier campers 12K+ yet the manufactureres continue to sell them on new units. Yours will start having little bumps here and there and a tread line that raises above the others if you keep running them ... I've seen this over and over on MaraBombs others in my camping group had. Even though it says GoodYear on the side of your tire ... they are made in China like all other ST (trailer) tires sold in the US and I mean ALL. Many of us have gone with LT tires (Michelin, Firestone, BF Goodrich) if your weight isn't over their capacity ... otherwise GoodYear G614's are about the only other safe option. G614's are pricey! You can sell your MAraBombs to farmers to get back some of your money ... they slap them on their farm trailers that seldom see high mph and loads in excess of 12K. GET RID OF THOSE TIRES!

Why not take that tire to a Goodyear dealer? The Marathons have a 6 year warranty. They should replace it. I'm not arguing for or against using these tires on your rig, that's up to you. BTW the Maxxis ST tires I purchased earlier this year were made in Thailand.

tire bigger
My guess from prior episodes with it is the larger tire needs immediate replacement and adjustment from goodyear. It is about to separate the tread from the tire carcus.

That is a WTH question?!? Looks like 2 different tire profiles. The right one is a square profile and left a round profile. I just changed the tires on my truck and the new tires(different manufacture) look narrow and taller because of the profile, but are the same size as my old set.

I had a tire do that on our class C a couple years ago.
They were the Michelin recalled tires.
I noticed it while on a trip at a fuel stop.
Tried to make it a few miles up the road to a tire shop but it blew before I got there.
I believe they called it tread separation.
Was covered under the tire warranty.

This can happen when the steel belts in the tire break. Just replace it with the spare for now and get it replaced. If it's under warranty, I'd go that route :)

Check the rim size. If one rim is wider that the other it would account for the squatty, wider tire profile.

Looks like that rim may be more narrow than the other rim. Just an observation.
