Marathons don't bite the dust! People overloading, over speeding, or under inflating does though.
I have been rving long enough to know that there will always be people wanting to blame their miss-use of rubber on the manufacturer and never on themselves.
Jim (who has been doing this for more than forty years).
I see you're new to the forum, Jim. Welcome.
You're not the first to assume that it's owner neglect causing the Marathons to explode.
You may want to go back and read all of the posts listed under Tire Reports, and there are many more reports about these tires on the Casita Forum
and on the Internet.
Owners have experienced blow-outs even though they weren't speeding / underinflating / overinflating / overloading, and their tires weren't old or worn -- or whatever else you can think of.
The Load C tires just aren't up to the job.
Thanks for the welcome Eileen.
I didn't mean to step on anyone's toes but Marathons are the largest selling tire there is for small trailers (at least from what I recall).
I find it hard to believe that they manufacture a poor brand of tire year after year. Even harder to believe is that if all these users have had all these problems all these years then Goodyear would been sued or something. So I'm left thinking as I said, Marthons are good tires. So what could the problems be?
I put together this list of variables:
The common ones would be "I" for inflation, "S" for speed, and "L" for load.
One variable most commonly overlooked is pavement temperature. Hot Georgia asphalt vs a cool Wyoming interstate. Call this "T"
Another variable can be road type as in chip seal or gravel etc. Call this "R"
Another variable is storage. Covered from the sun? On blocks? sitting unmoved for a year on one side of the tire? Call this "ST"
I x S x L x T x R x ST (this formula came from IRV2 forums) = tire life.
Since they are all variable then one would expect the tire life to be variable too. All this to point out there are other things to consider.
But taking this to the ridiculous, if you never drove over 40mph would you expect the tires to last longer? I'm sure you would and that is the point. All of these things work together to determine tire life and they are all variable factors in an equation.
Since I have difficulty with the "marathons are bad tires" I have to make a leap to conclude that the load C is probably too light for these trailers that grew in weight year after year because now I see you can order them with Ds.
I did read on IRV2 (or Scamp) where some people were putting D load truck tires on their rigs and that solved the problem too.
New to your club, old to these issues
Thanks for reading
