Our 03 Goodyear Marathons still look good after 30,000 miles. We have a light
trailer, store inside, drive 60 mpg, and do not live in the heat. Since they looked good to us we took them to our Goodyear dealer to get his opinion since they are 03 and you guys always warn us about old tires
Fred took the wheels off and took them to our Goodyear guy. He was not at all concerned about the age of the tires
because of the condition they are in and the storage conditions. So, we will give them another season.
I asked where the tires
are made now. He said, "all trailer tires are currently being made in China". His reason was that there is now a 37% tariff on passenger and truck tires coming from China. So the US wants to make passenger and truck tires here. We do not have the capacity to make all tires so the ones they outsource to China are trailer tires.
I figure I want to keep the ones I know about and I'll change them out with the unknown when necessary. Hope this works for us this summer.
