Funny you asked, I happen to run those tires on my truck. The dealer installed them prior purchase, and so far they are pretty good. I was told by the tire guy that they are the best HD tire used out there?...? I know they are expensive to purchase, and have like an 80,000 mile service life from what I was told... Anyway just his thought, mine will be after many years of service. Yes they are sold to be or supposed to be a commercial tire. Not really ruff riding, and have had no problems stopping on wet pavement with a load being pulled. Also to add they are not bad in dirt either, sugar sand makes the back end hop just a little. Overall in only 4k miles I have no complaints. Their pretty stout from what I have heard via internet research. Hope this helps.
