I run 10ply commercial grade tires on my 16" F250 wheels and haven't had even a flat since I started using them 6 years ago. I do quite a bit of brush running, so that's remarkable in my opinion. In less than 3000 miles on my Blazer, I've stuck a mesquite thorn through a sidewall on one tire, and punctured two more sidewall's on a broken mesquite stump. Called my tire dealer and he said he doesn't carry any 10 ply 15" tires. WTF?
