      Great tires

      Aggressive looking tires, great for any road and weather condition, got a lot of jealous looks on the road

      Great tire

      Excellent customer support and shipping from ET. Tire is very smooth on the road, virtually no road noise from a 35 12.5x20 with this aggressive of a tread, I was pleasantly surprised. They grip the road well in wet conditions and with winter fast approaching in northern Ohio I’m excited to see what they’ll do !

      Perfect !

      This the perfect tire for both on and off road and performs great in the snow. There was a slight increase in road noise from my stock tires but I guess that's to be expected. Fast shipping and excellent service from Extreme Terrain.

      Cooper S/T Maxx

      I’ve had these tires in my ‘13 Wrangler for about 6 months and I have zero complaints. They’ve done great in mud, on rock and in snow.

      Great tire

      The person that thought these tires are harsh likely was running too much air. They are, after all, a heavy ply tire. On my JK with 28 to 30 psi and Rancho 9000XL set to 1/1, it rides better than stock. Best part is they last forever and have excellent Off-Road traction. Very quiet.

      Review from Cooper Discoverer S/T Maxx Tire - 35X12.50R15


      This isn't a typical brand you think of when it comes to all terrains but they are pretty alright. However I think they are less grippy and surprisingly more harsh than KO2s. I would probably spend the extra cash on bf goodrich
