Trailer tires have a stronger sidewall that is designed to take the shock of the trailer bouncing. Cars and trucks have a way softer suspension that doesn't abuse the tires nearly as hard as a trailer does. At least that's what the tire shop guy down the street from me said when I changed my car tires for trailer tires.
Yes, with what Blueblazer said.
The other thing has to do with tandem trailers and their turning.
Trailer tires are much more rigid in the sidewall and will hold their shape better when being turned.
Radial tires have a softer sidewall that flexes a great deal when turning with a tandem trailer.
Radial tires, because of their softer sides may also contribute to trailer sway.
I assume you are talking about using these on your boat trailer. If that is the case, these boat and trailers do not weigh very much and sway probably would not be an issue if you pull with a truck that tends to have a stiffer suspension.
If you are talking of something like an enclosed trailer that is heavier, that would be a different story. I would then recommend a trailer tire.
An alternative to both could be a truck tire, they have stiffer sides also.
My information is from what I have been told by places that sell tires. It makes sense, but I still use radials because they look cooler.
It's not a very good reason, but I still do it.
