A new set of these Ironman RB-SUV tires came on a used 2015 Grand Cherokee we purchased. So far, we have about 30,000 miles on the tires, and have driven with them in all conditions except snow. The treadwear seems in line with the 55,000 mile rating on these tires. My biggest complaint is how mediocre these tires perform in wet conditions. I have experience some hydroplaning, and the tires seem to lose their lateral grip in wet road conditions MUCH earlier than other tire brands (Sumitomo Encounter AT, Falken Wildpeak AT3Ws, for example). As a result of the poorer-than-desired wet weather performance, I would not buy another set.
