Where do you guys go? Smithville marine doesn't do tires. Stopped by Croft this morning, they didn't make me feel to good. First tires they offered were C rated. I even had the boat/trailer up there. C rated tires aren't gonna work on a single axle trailer. Any other recommendations? I've thought about buying some on tire rack but I like the idea of having a place to go if something goes wrong with them vs an online retailer.
