These tires are mounted on a ram 3500 that mostly carries a 3k lb truck camper, hence the need for a 12 ply F rated tire. I have not had the opportunity to drive in snow or ice yet so will update after I do. So far the tires perform better than expected, road grip on dry pavement is excellent as is loose gravel and off-road. Grip on wet pavement is good. They are surprisingly quiet for an aggressive tread. The ride in the truck without a load is harsh as would be expected from such a stiff sidewall. With a load, they feel confident and responsive. The tire shop had a hard time balancing two of the 4 tires delivered, he took them off and reinstalled on the rim twice to try to get them right. He said they were very difficult and so put those two on the rear wheels. The other two balanced out fine. He used traditional lead weights and not beads which he said may be what the two difficult tires need. So far I am pleased with these tires. They exceed my expectations.
