Guess l was hoping to get a consensus on the best available tires to use on a dulley carrying a 5000 lb TC. I'll probably look into the Toyo brand for my next set. I believe heat could be causing most of my separation issues as in summer months as read on my TST monitor I can see Temps reaching 110 degrees with pressure rising at least 10 to 12 percent. A few months back I opened the trunk of a car I own to find a BFG TA exploded Tire was 6 years old with very few miles used as spare,also vehicle is always garaged. I tried to post a photo, but couldn't. I'd be happy to email or text the photo to anyone to post. Just private message me..... So its my opinion most if not all tires are not made well these days. Just read trailer or class A form...
