Satisfied

They hum a bit at low speeds and it increases at highway speeds but to be expected with mud tires. I've heard many that were a lot louder. Good looking and seem to handle o.k. on wet pavement. Haven't done any serious off roading with them yet so will update later. They better work good @ $1971 for a set of 4 tires. Thought for that much it might include some stock in the Cooper co. LOL.

Awesome tires

Background: On my daily driver wrangler that mostly goes over NYC potholesI have only had these tires for a few months but so far they are awesome. They are pretty quiet for hybrid mud tires, work well in the rain and do not hurt my already terrible gas mileage lol. I haven’t used them in snow yet so I can’t comment on that but so far, they are doing everything I asked of them.I would also recommended to check out the specs on Cooper’s website on the size of the tires. I got 295/65/20 and I have yet to find a spare tire cover that fits...plan accordingly.Update 1/4/19I went to Rausch Creek, Pa to do some off-roading and these tires are legit. At one point, I had a rock poking my tire with no issues, even waited there as my brother took a picture lol. Went on some green,blues, blacks, went through streams and mud with no problems. I probably could have done even tougher trails but I didn’t want to break anything. At the end of the day, I aired back up and was on my way. Again, I one hundred percent recommend. Looking forward to see how they are in the snow but I am sure they are great.

So far, so good.

So far, I’ve had theses tires on my f150 for 1300 miles. They are a little louder than I was hoping for, but I wasn’t surprised due to their aggressive design. They are a little louder than the Ridge Grapplers. They are similar to the nitto m/t on the noise level. They are reasonably smooth. Most of my driving, so far, has been on the highway with some on gravel roads. The tires look good with their aggressive tread design. The tires seem to handle as well as my ridge grapplers.I have reasonably high expectations for the mileage since that has been my history with Cooper tires in the past, but only time will tell.I have 7000 miles on the tires now, and they are holding up well. They’ve performed well through the summer on these hot Texas and NM roads. They do pick up and sling rocks if driven down gravel roads.
