Me, too. /forums/images/graemlins/frown.gif On the round trip to Alaska and back in '72 with me pulling a travel trailer, my parents pulling a travel trailer, and an aunt and uncle with a pickup camper, we experienced 17 flat tires. /forums/images/graemlins/tongue.gif Then my '89 fifth-wheel trailer came with ST (trailer) tires, but they were bias ply. I made it all the way to Anchorage with it in '90, but found when I got there that two of them had big bubbles in the sidewalls. I believe the first radial trailer (ST) tires were made by Goodyear in '89 or '90 and I put them on the fifth-wheel when we got back south. Goodrich came out with their own radial ST tires in '91 while I was back in Anchorage working at my brother's tire dealership. Personally, I wouldn't even consider bias ply tires on anything that was going to be used very much because the radials will last enough longer that they're cheaper in the long run.
