When on the road with a trailer, I automatically carry a floor jack and jack stands. Many call the Chinese tires on boats and RV's "willpops," and failure rates are ridiculously high.

My new GD 323BHS is arriving the next week or two, and I'm going to replace the tires on day one.

I've researched various RV forums, boating forums and diesel truck forums. The below tires are the top quality non-Chinese tires for our use. Lowest delivered prices found online are:

Bridgestone Duramis R250 $232 TireRack.com Rib tire.
Maxxis M8008 $160+delivery. DiscountTireDirect. Great quality ST radial.
BFG Commercial T/A $168 Amazon.com Rib tire.
Michelin XPS Ribs $298 Treaddepot.com Rib tire.
Goodyear G614-RST $399 Amazon.com (G weight spec'd.) Special trailer tire.
