dude ive been using goodyear viva 2 tires(from walmart!) for my dual axle boatmate trailer for ever and had zero issues .I tow a lot and drive like i dont have a boat behind me and again no issues.
they are half the price and last just as long..
het but if you feel its better and safer pay twice as much for piece of mind.
I know many people with newer boat that had a bunch of issues with their trailer specific tires blowing out afgter only one season ,go figure!
must have been those recall issues
