Great tires at a good price point.

Very good looking tires. Low road noise for such an aggressive tread. They ride nice. So far I love these tires and the road wear warranty is pretty good.

Great Tires. Happy w/the TIres and the Sams Pros.

Time will tell on wear and how they will hold up in the woods, but based on reviews and on Sam's Club's warranty, I am not real concerned. As it is, really like the tires, the first replacements on my Ford F-150. OEM was Perrelli Scorpion ATR, I learned much from that experience, w/those tires done as far as tread at just about 30k, plus they were really sad excuses for All Terrain tires. Well before down to wear bars, very little rubber to bits.. I found I would be squealing my tires a little at stop lights, without real significant acceleration...Not real assuring when thinking about icy winter roads..... I found out the rapid wear is common with OEM tires, they are typically built different than aftermarket equivalents, but with all the tap dancing between Ford and Perrilli when it came time to talk warranty, I walked away w/an education on buyer beware on tires w/new vehicles. But anyway..... These Coopers are amazing so far. The tread is awesome... Makes me want to shine them just to show them off, and I typically am not the advertising sort. Just as quiet as the Perrelli's were. ... meaning that I do not hear them at all. Especially with the music going even at a low volume. The ride is a little firmer, but not in a bad way.... just feels a little more solid, a little less squishy.... I prefer it over what I had. The standout thing about these tires compared to the Perrelli Scorpions is the responsiveness... So much difference that when I first drove away from Sam's, the tire response was so much crisper it was almost a little dangerous as I adjusted to the difference. These tires just grabbed the road and did not let go.... .
