Trailer tires are a really good point by Seahawk that are often ignored. Not just good tread and no dry rot, but trailer tires that are rated for the weight and speed you intend to tow. When I towed my boat, almost all of the trailer tires in the appropriate size were rated to a maximum of 55 MPH. The most expensive option, I seem to recall a Goodyear, had an appropriate load rating and were rated for I think 85 MPH. I never had a single issue with those tires. Also worth noting I always had my double axle trailers aligned which helped them pull true and resist sway.

I have the Goodyears on my Lance TT. They have been great.

Trailer tires indeed a HUGE deal! I also just ask my trusted local tire shop to put on whatever I'm least likely to be reading on the side of the road some day. Price be damned!
