I need to replace the 6 tires on my 38EC boat trailer. Any suggestion on the best brand/model of trailer tire?

TIA - Butch

There are MANY threads and thoughts on this topic.

Biggest question is what size wheels? Do you have 16" wheels already? The majority of folks with that size of a boat run 16" wheels with either E-Rated LT truck tires, 235/85R16, like a Firestone Transforce HT.
...OR...
They have moved up to a G-rated RV based trailer tire like the Sailun or Goodyear G614 RST in the ST235/80R16 size.
NOTE that going to the G-rated tires usually increases tire weight by 50%. But most folks who have stepped up, are happy with the setup.

What he said... They are pricey but pull nice. However in my experience, all boat trailer tires will implode long before they "wear" out... So, it really depends on the amount of road wear vs. sitting that will justify the higher price.

I replaced all 6 of my tires and wheels last year and went with Boar aluminum 19.5 wheels and Double Coin RT600 Commercial Truck Tire - 225/70R19.5 128M LRD 14PLY Rated. Yes you can get Michelin or whatever you want to spend -- I've had good luck with Double Coins in the past and will not put huge miles on...
Not everyone needs this setup but I can tell you that they ride, and pull amazing, and are very stable when cornering on the road and in a tight parking lot. Not to mention i think they look great! These are as close as you can come to running semi tires on a normal boat trailer.
My Myco is rated for 24,000 lbs and the 16 inch wheels were maxed out.

I’ll be putting 215/75r17.5’s on my next trailer and never have to worry about tires again…

the 17.5's are the same height as 16" and are really tough. 1 failure in the 4 years I have been using them on 6 different trailers. total of 34 tires. That was from a curb jump loaded on a tight turn.

i have ran carlisle radial hd's for years. but i rotate them out ever three years. i think old age is more of a problem than brand.

Yes, my 38EC's triple axle trailer does have 16" tires; ST235/85R16's. The current brand is Carlisle, but they definitely need replacing.


I don't trailer my boat very many miles per year, and boat and trailer are stored inside when not in use so UV isn't much of a concern. I'm curious if anyone has experience with the Goodyear Endurance trailer tires? I understand these have very strong side walls and are built strong enough to get a "N" Speed Rating, up to 87mph (not that crazy enough to pull my boat that fast), These GY's have a E Load Rating (3,640 lbs) and they are 10-ply.

14 ply. then forget about it.

I have them on my triple axle trailer. I’ve put about 3,000 miles on them in the past five years. They still look like new. Smooth ride and solid quality. At the time, 2017, they were the only trailer tires made in the USA. Not sure if that’s still the case.
