Well I haven't used them.....Yet! I am in the process of putting the HSR2SA's on my MH for all 6 tires. I have a friend who owns a trucking company who swears by the continental's in general and these tires for motorhome applications. In my case I will have almost 3000 lbs of extra capacity on the front axle. The HSR2SA's are also a J rated 16 ply tire. Sorry I can not answer how they work yet, but I feel good about my purchase.
