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

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

***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
