I almost went with Maxxis but I wanted new wheels and Treddit did not offer them as an option. I've ran Marathons on all 4 of my trailers for thousands of miles over a 16 year period and have had zero failures. Therefore, I was comfortable sticking with them. However, just as with Carlisle some folks have had horrible luck with Goodyear. I've heard nothing but good on Maxxis.

Thank you.

I can only fit the 205s on my little boat's trailer.
Currently running 205/75/14s at 26.11" tall.

Going to jump up to 205/75/15s at 27.11" tall.
The 225/75/15 at 28.29" tall; and nearly and inch wider is not going to work.

The trailer was built in 1976 or so. Everything was smaller back then, myself included.

I installed a set of Maxxis 225/75/15 E load and couldn't be happier.

For some reason my trailer is 1981 and has "Turbine" style "Mags" that are 14x7/ I do not know if you can (scratch thay SHOULD) put a 215/75/14 on a 14x7 rim...Anyone. If I don't use these I will buy a premounted tire/wheel.

You think the wheel is too wide?

If is is a single axle trailer you can use an automotive tire with no issues. I would look to go 15" in a lower profile if it will meet your weight needs.
