Thread: Trailer tires ???

I have Good Year Marathons on mine and they're doing good, been about 4 years now.

I have the endurance, made in the USA. I probably only have 2000 miles on them.
So far I am really impressed. They pull really well.
Another thing mine were made in April I bought them in June.
I would buy them again. Just don’t have enough miles to give you a good idea on wear.

I went through a set of tires every year for the last 5 years with the same cupping problem (tried different brands) and switched to the new Goodyear Endurance 215/75 R 14 ST last spring and they show no signs of cupping and very little wear. I would definitely buy the same ones again.

The trailer manufactures put the cheapest tires on they can find to keep cost down. Get the endurance.

And, the majority of these tires are speed rated for a certain speed. A lot of people don't know that. Cupping is usually due to a condition called "cording". The boat bounces which breaks the cords in the tires. You really do get what you pay for with boat trailer tires.

You might try taking it to a trailer shop. I had one do that on multiple sets of tires and finally took it to a shop. They said the pre-arch in the axle was too much for the weight of my trailer. He took some of the arch out of the axle and it hasn't torn up a tire since. Just an idea......

What ever brand you get, get them in radial. Cupping is a natural chartiristic of bias ply tires in a free rolling application. Almost impossible to stop. And run at least 45 lbs of pressure.

What does the whole rig weigh, What is the axle rated for, what tires and what air pressure do you run?

At that kind of mileage I’d be looking at the trailer. Cupping is a sign of tires hopping. The normal source is a worn suspension or a bent axle. Your suspension may not be worn, but something could be loose. Could be you are too lightly loaded for the camber in your axle.
