Goodyear Marathon Tires

[Ins. Man]

Where do I find the manufactured date on my tires and if the tread looks good etc. at what point do I need to replace them due to age?
Thanks

On my US made Marathon's it is marked on the inside as mounted, so you have to crawl under the trailer to read the manufacture date.

on our trip to NS & PEI the first day out the tread completely blew off the Marathon. Used for less than 2 years at least every 6 weeks. Changed all 4 to Carlisle Es 10 ply.

I too am running the Carlisle E's but I only inflate them to 65 cold vs the 80 recommended. Once hot the pressure is up to 70psi (100* outside temp at 60 mph sustained.)

I know there are concerns that the E rated tires will beat the trailer to death but according to my weight there is two thousand pounds on each tire.

I will keep reporting on them.

Thanks Vin

There are many threads on Marathons, tire age, and such. Try these:

This is probably more than you wanted to know. There's a very long Marathon thread I couldn't find.

Date of manufacture may be on the inside or outside depending how they were mounted.
