Cooper Discoverer STT Pro Mud Terrain LT255/75R17 111/108Q C Light Truck Tire

These tires bite well in off road conditions and ride fairly well on the highway. They are a little noisy on the pavement, but that is expected for such aggressive tread lugs. I would definitely buy these tires again for my GMC Duramax 2500HD.

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.
