Beats the stock wrangler tires to pieces
Very satisfied with this purchase. The tires exhibit an Excellent & smooth ride, extreme traction, and are surprisingly quiet for a tire this aggressively treaded. The most noticeable aspect of these new tires is how they slice through and practically laugh at the water on roadways. While the stock Wranglers I ran for years had a tendency to hydroplane-- these Cooper's slice through water like a knife through cheese, never mind the very tough but good looks. I'll stay with Cooper from here on out..Oh, and special kudos to NTB who had no qualms about installing a slightly oversized tire after they thoroughly investigated my 4x4 Longhorn's clearances.

Great Tires!
I really like these tires so far. Much less noise than the 33x12.5x20 that were on the truck when I got it (2012 f150 platinum). Great amount of traction and no issues so far. (roughly 1k miles in) They look rugged enough with normal functionality. Definitely happy with the purchase!

Great yraction
Been on the sand in Outer Banks and was very impressed even with my deisel f250 I had zero issues. Even pulled a couple stuck trucks out never even lost traction. Ride great and are very quite on the road.

Amazing highway ride!
This is my fourth set of Coopers. And they are great! Each set has gotten better! These are 275/65R20 on my 2014 Tundra with a 3/2 ReadyLift. They are quiet and smooth.

Dont balance well
Tires all took tons of weight to balance and still have a vibration. Not happy that they shake on my new f250

One of the best tires out there
These are great tires! I have ran them on 3 different trucks and they have never let me down. They clean out good and do fairly well in mud and on the highway.

So far I’m very happy!
These are great looking tires that are quiet and daily driver worthy. I only have 1,000 miles on them so don’t know how well they wear yet. Very happy so far!
