Purchased from purely power sports 35/12.5/20
Ordered these tires on Tuesday and they arrived on Thursday via FedEx. Amazingly fast, authentic and exactly as described. Thank you thank you! Will update performance at a later date but maaaaan do these look tough 💪 Ok, I'm back. Balanced well. Roll smooth. Surprisingly quiet. Hold the road. Look badass. Amazing tires and they're F rated. Did i mention they look badass? If you're shopping for tires, look no further fellas. You won't be sorry

Good price, good quality and rides good on pavement
I got a set of 265/70/17 on a 2011 Toyota Tacoma. The tread is pretty aggressive. A little chunkier than I expected, but I will put them to use. Even so, the tires still fit the stock rims without any rubbing even with articulation. Road noise… minimal. My old K02s were far worse. No bouncing and my tire guy got them balanced the first time. I haven’t taken them off road yet, but very pleased so far.

Impressive to say the least
***UPDATED*** Mother Nature finally allowed me to get a better idea about these tires. I have so far run them through deep mud, heavy rain (1” an hour or heavier), dry roads and on mild rocks. No sand or snow here in Central Arkansas this time of year. So I haven’t aired these down at all, been 36 psi. In the wet these are great. Plenty of contact in heavy rain to provide a feeling of confidence at hwy speed. In the dry these are VERY quiet for such an aggressive tread. I have honestly had more tire noise from some AT tires. In the dirt and rocks these take everything I throw at them and want more. I easily scrambled over everything I encountered on the trails. In the mud these tires clean themselves out nicely. I had no caking as I rolled through mud about 1-2” deep. I am very pleased with these tires. Worth every penny I spent and will gladly buy again. Hope this helps y’all a little. I will update snow when winter comes around again. For now, kudos to cooper for a great set of tires

fit my 2016 silverado perfevtly,could not be more pleased,fast shipping too
really like these tires,only have about 200 miles on them so no idea on how they will wear, they look great on my chevy, balanced easily,went out in a rain storm and they were as good or better then the factory tires. cant wait for some snow! was really amazed how fast they were shipped....i really like these tires and the seller. Update: i purchased these 12/22 it is now 8/24 the above review was apparently never submitted ,but i do stand by what i said. now a little under 2 years of running them i felt i should update. only put about 6000 miles on them,but the performance in the rain is fantastic,not very much snow over the winter,but we had 10" once and did not even need to pu it in 4x4. i did just to keep the frt.diff. lubed,but it was not needed. absolutely love these tires,may buy another set just to have on hand in case i live longer then i expect..lol rarely leave reviews, but i had to ,probably the best item i ever purchased from amazon. hardly any wear at all,and still very quiet.

So far so good.
I’ve put about 3k miles on them and they have been good. No excessive noise or vibrations. They were easy to balance. Good traction in the rain, snow and mud. Coming off the pirelli scorpion stock tires, I did take a MPG loss with these. About 6-7mpg on highway even though they are the stock size.

Very nice-looking tires and they don't make noise!
They look great and are nice and quiet! I put them on my 2022 Ram Limited diesel, and they are a very nice ride. I have not taken them on the highway yet, but I will update my review after I get a chance.

They’re okay
It’s definitely aggressive looking but it is a bit loud.
