I bought a very nice used Trailex (aluminum) that was a few years old. It had been stored outside in Colorado. Towed it home and my 911s around town a little without any problems. Started out moving cross country on the 4th of July Weekend (one of the hottest on record). Packed the bearings but the tires looked very good (no cracks. plenty tread) and the trailer was light as was the car ('74 911). One by one, each of the four tires blew out and the spare. It was hard to find any tires as it seems everyone was having the same issue (same tires and many campers/trailers). We had to spend the night in a WalMart parking lot twice waiting for a tire store to open the next day. Wife was not amused. Replaced all the tires and the spare. That was ten years ago. Tires still look like new as have not used it since. Next trip gets all new tires...no matter how they look.
