Even the Maxxis are built in Taiwan as well as other Far East countries. Goodyear Marathons are often bad mouthed due to numerous reasons the main one being run low on pressure and thus they explode the same as any other brand, Maxxis included. Goodyears just happen to be a more popular brand and therefore more comments. Strongly suggest that whatever tire you buy, make sure you get a pressure monitor and keep them properly inflated.

I am still debating the virtues of tires. I have ran many different tires on all kinds of trailers hauling much more than the weight of an average camper.
I have seen far more trailer tire failures than regular tire failures.
It wasnt that long ago that nobody would dream of running radials on a trailer, now that is the norm.
Yes, they are designed differently, but you cant say passenger car tires and LT tires dont get severe twisting forces in hard cornering. Trailer tires get their twisting at parking lot speeds, car and truck tires get them at higher speeds and seem to last a lot longer for some reason.
I do run ST tires on my camper and my current utility trailer tires are a mix.
I have ran LT 10 ply tires on equipment trailers toting 20k+ loads with 0 issues.
A family member bought a new trailer with upgraded tires (not bottom line junk) and blew 3 of them within 1000 miles. I have never had that kind of issue even running used car tires on a trailer!

Now, when the time comes to replace my camper tires, it will get a set of STs. I will be making an extended trip towing 6k on my 16' utility trailer soon and am debating on replacing the tires for good measure. I will 99% most probably be putting new STs on it too.
As for brand, I quit buying marathons years ago when the prices got above $50 each and they seemed to blow apart every time we hooked the trailer up. I do like the maxxis trailer tires and interco has a good offering at a good price.
I am starting to feel that a quality LT tire is the better way to go if they are offered in a size you need.
This is just my$.02. The tires on my camper are the cheapo ones that came from the factory and I havnt had any problems so far, but it honestly doesnt get that may highway miles on it and they are starting to show crazing on the sidewalls at under 3 years old.

edman87k5 I think everyone needs to run whatever he/she feels they want to run. There are 4 reasons tires blow and they apply to every tire manufactured, regardless of who builds them or where they are built.
1) Overloaded
2) Under/Over inflated
3) Road Hazard (Nail, screw, etc.)
4) Age of tire (worn, rot, etc)

They are Goodyear Marathon load range D and yes it says made in China on the side of them. The tread is like new and there is no cracking in the sidewalls. donn are you saying they are likely not good due to the age? Thanks again for the input.

normal is 7 years, but cracks in the sidewalls are the indicator.

1.1 inches "taller" may not seem like a lot, but you should really need to be sure you have adequate room above the tire to the underfloor to be sure. One good bounce could cause impact with the wood or metal fender well and cause a blowout(s).

Tires loose elasticity as they age. This loss is due to the internal lubricants and UV protectants between the polymer chains in the rubber (blended at manufacture based on tire type and anticipated usage) leaching out over time. How the tires are stored can effect how quickly this happens. Most "garages" store their tires "up in the loft" where conditions for tire longevity are awfuL. Heat, humidity and light kill new tires. You can have brand new tires improperly stored that "over age" in as few as three years; when if properly stored in a cool dark environment can last for several years more. (That is one reason tires are individually wrapped in barrier paper - shops that "peel" their tires to make them look good on the racks are killing their customer's tires.).

ST tires have more added at blending because the normal usage is very limited and a lot of time just standing around. LT and P tires have less because that are in motion far more often than St tires. That flexing motion circulates the lubricants and UV protectants to the surface to keep the tire flexible and "uncracked."

As tires age they get brittle and can crack from the inside out. That is why "over age" tires should not be used (especially when your house is the load they are carrying - IMO).

It would only be 0.55"(radius difference) closer to the inner fender. The 1.1" is the difference between the tires themselves.

Thank you, I misunderstood. The rest of my post is still valid.

We have a "tire guy" here and I will track down his username and you can PM him.

Found it - WMTIRE

As I understand it, radial run cooler than bias tires.
That is always a plus in a trailer tire.
