Some of the causes of trailer tire failure is under inflation and over weight. Good idea to always check the air pressure in the tires. Also know what the unit weighs. Few bucks at a cat scale with tell all.
This may open up a can of worms, but I'm a firm hater for chinese tires. If you research all the blowouts on RV's most all are chinese manufactured. Now that being said, seems right since most rv companies use them because of cost. Also there is good chinese tires and bad chinese tires. The tires on my unit are chinese, and told they are the better ones. Have no idea how or why they are better, just sometime in the near future they will be replaced with LT tires. I ran Goodyear Wrangler, Kelly Springfield, and Firestone Transforce on my 2000 Prospera and replaced only because they wore down/age. All were LT tires. The Goodyear's were factory original, and although I didn't run many miles on the Firestones before trading it in, felt these were probably the best of the 3. So more than likely that's what's going on the current rig.
Having a blow out on the road can be a pain if not dangerous. Also the possible damage caused by a blow out can be expensive. Prefer to do whatever to keep it from happening.
