I agree that U-Haul uses bias ply on their trailers, and would like to add my opinion as to the reasons. I would bet the vast majority of people renting U-Haul trailers are not experienced trailer towing folks like us. Probably way more instances of curb hitting per 100 road miles travelled. They are probably more durable in that situation. Also, The u-Haul people are not at all concerned about their customers fuel economy, Just the companies own costs, and I would bet they get their bias ply tires quite cheap by the container load. And just think, every time someone blows one out, they get to charge the customer for a full replacement at retail price. They probably rarely replace them due to tread worn out. Now add in the fact That the bias ply tire is less likely to tear the fender off the U-Haul trailer, And we have a winner.
Those all sound like compelling reasons to go with bias ply tires on the travel trailer. It's all about overall cost. Coming home from Jetty Park Campground today, we hit quite a few bad spots on on I-4. I have on occasion had to crawl over a curb with the right side trailer tires to clear left side obstacles with the truck. I wonder what the fuel mileage difference really is. I have Carlisle sport trail bias ply tires on our boat trailer. They seem to run fine. Cousin's truck is diesel so hard to compare his mileage with his bias ply tires on his travel trailer to my gas F250 and radials on our travel trailer.
