Will Going to a Tire with Higher Ply Rating Prevent Blow Outs on a Livestock Trailer

Question

Question:

So in our case, the tires were inflated to the upper limit of 80 psi. Trailer was not overloaded. Tire blew and tread came off like a peeled orange. Other tires of same brand had 96psi according to gauge 15 minutes after we stopped. Tire brand was PowerKing. We deflated to 72psi and traveled on. When stopped 2 hours later, psi was at 83psi per tire. No more trouble. I get a different suggestion from everyone I ask. As a tire salesperson, your opinion? Do I just buy a "better" tire brand of same plus?

The main reasons why trailer tires blow out is heat generated from under inflated tires and overloading the tires. Trailer tires should be inflated to the maximum psi indicated on the tire. A tire in the same size but with a higher ply rating would be able to combat some of that but can eventually have the same issues. So when inflating trailer tires be sure to go to the max psi.

With that said the 14 ply tires will definitely hold up better than the 10 ply. For an ST235/80R16 tire, load range G with a 14 ply rating you can use the Taskmaster Provider tire # PRG80235. It is rated for 4,080 pounds at 110 psi. Make sure your wheels and valve stems are rated for 110 psi to avoid air leaking out. Valve stem # AM20906 is rated for over 100 psi applications.

Well, I'm not a salesperson, so the information I give you is just so you are informed. Trailer tires should be inflated to the max psi rating on the tire. Otherwise the capacity will be lower and the tire would generate excessive heat. The heat happens because trailer tires are built with a thicker sidewall to handle more vertical load. When under inflated that thicker sidewall generates more heat. Not all tires are created equal but what separates out the better tires is higher quality for one but also tires from Westlake, which we do carry, have a 5-year warranty and complimentary roadside assistance for 2 years. So if the trailer got a flat you would call the help line and a tech will come change the flat for you. You can call 24 hours a day, 7 days a week, and 365 days a year from anywhere in the United States, Canada, or Puerto Rico. In the 235/80-16 size in a Westlake tire the highest load range we have is a load range E, # LHWL401, rated for 3,520 pounds at 80 psi. You could go up to a 235/85-16 load range G, # LHWL410 which is rated for 4,400 pounds at 110 psi. This size will fit the same size wheels as the 235/80 but the larger tire will be about 3/4 inches taller and the wheels may not be rated high enough for this size. I have linked videos on both of these tires for you.
