I have a Carson tandem wheel car trailer that seems to "eat" trailer tires. I normally use it for hauling a vintage race car which weighs less than 1500 lbs. Probably half of the time the trailer is towed empty as I go to pick up a car or parts. With the loads being light I would have thought I would get longer tire life. The tires seem to be wearing evenly although at slightly different rates. What has been your experience on tire wear on tandem wheel trailers? Are some brands of trailer tires better, in this regard, than others? I have heard that all the trailer tires are made in China and that is part of the problem... is this true?
