[Too Many Projects]

Good reminder and catch, Freddie. The wear on the separated blocks indicates it was coming apart the last time you pulled the trailer too, lucky man.

Check air pressure !! and keep them at, or near max, as the load rating is based on that pressure. Running the air lower than max also reduces the load capacity, which allows more sidewall flex which builds heat in the tire and heat kills tires. I have load range E tires on my trailer. Way overboard for the gross weight of the trailer and load, but I've never had a tire fail either.

As an aside, I have a 2013 travel trailer that the spare had never been off the carrier and 2 years ago, it separated and was coming apart. The quality of tires has deteriorated dramatically with many of our tires now coming from china.
