Great customer service. Tire Company shipped on time. Delivery service was horrible. Received 3 tires within 4 days. Last tire showed up 3 days after first 3. The tire shop was excellent but fed ex delivery didn't deliver all 4 tires at the same time.

Best off road tire!!!
These are excellent off-road and dry road tires, not so much in the snow unless it's deep and you're aired down, as with any MT tire. This is my 2nd set, do not get stuck, they love the mud, dirt, and rocks, dry rocky creek beds, hills, they really shine!! Quiet for MT tire, and the drone at highway speeds is not as bad as you would think about 1/2 of other MT tires. The sidewall is really strong I go through shrubs, trees, bushes completely off road that is anywhere from 1-6 feet tall never a puncture. My last set did not chunk off either couple scraps from rocks, but not deep all surface area and never a chunk missing like others. I abuse these things and they are great. Tread is 2 ply steel, 1 nylon, and 3 ply polyester, the sidewall is 3 ply polyester. Great tire!!!

Best tires ive ever bought
Had these on for about 500 miles or so. Had more road noise than I was expecting after reading reviews but I like the low whirling noise as a matter of fact I have 2 special needs girls and 1 especially doesn't do well on car rides. After putting these tires on she hasn't had any issues. I think the noise is calming to her. These have amazing grip on road and off. My driveway is at a 45 degree angle as well as my front yard. Also my yard holds water and stays muddy. I drove up my yard to the road with no slippage whatsoever. Before when taking curves you would hear the tires squeal with other tires but with these you can take the corners as hard as you want and they stay planted. So far without a doubt the best tires ive ever bought.
