Customer Reviews

Rated 5 out of 5 by Highly recommended Put these my Superduty and am very impressed with ride quality and noise for an agressive tread pattern. They held up to extreme abuse off road in harsh environments from mud sand snow rock. End of the day can take me home with a 10K load no sweat. September 15, 2016
Rated 5 out of 5 by Amazingly Tough, but Quiet, Truly All Terrain Tire! I put a set of these on my Toyota Tacoma and when I traded it for a Tundra, they had 38,000 miles on them and still had around 2/3 of the tread left. They were driven extensively off road on our farm in all kinds of weather in some quite rough terrain and I never came even close to being stuck and regularly went through stuff my friends wouldn't even attempt. I also pulled a 24 ft travel trailer, boat trailer and large utility trailer regularly on the highway and the tires performed perfectly. These Discoverer S/T Maxx's never let me down. I made 3 trips to Wyoming and each trip drove hundreds of miles on rough two-tracks and washboarded gravel roads, and I just let the air down to 18 psi and the truck rode smooth as silk over everything, while we saw other trucks skittering and bouncing all over the place. Got caught in a blizzard on one trip and the Tacoma with these S/T Maxx's kept on going while other trucks slid off the road in the greasy morass of snow and slick gumbo mud and muck. The only tires I've seen that noticably outperform these on pavement in the winter are dedicated snow tires that are NOT meant for offroad use. My wife hated riding in my truck with me because all the other tires I've run were so noisy, but on our first trip with the travel trailer she commented several times how quiet the S/T Maxx's were compared to the other tires, and that they rode lots better, as well. I like these tires so much that I've ordered another set to put on my new Tundra. September 12, 2016
Rated 5 out of 5 by Most Durable Tire Ever Seen I use tires in west Texas dessert country where rocks are sharp and slice tires easily. Prior to finding these I used BF Goodrich All Terrains on my F-150 and they chipped so quickly I was replacing every 10K miles. The Coopers are astounding in the durability category. No flats, no big chunks gone, still working well after 22K miles. Mix of highway and off-road. Just bought a new F-250, selling stock Michelins and putting the MAXX on immediately!!! Very satisfied.

Rated 5 out of 5 by Great great truck tire I replaced my Goodyear SRA's on my 2012 F150 FX4 with these and man what a difference. Im from WA so we see a lot of rain and a fair amount of snow. They have very good highway manners for the tread pattern and are very quiet. The only time i hear them is when you corner hard. These tires preform well in the rain and very well in the snow. Off road they are great. I have never been stuck and they continue to impress me, I can't seem to find terrain that they will not get me through. I cannot comment on there performance in deep mud but the mid I've been in they were great. My only minor gripes with them is that they collect a lot of rocks on gravel and dirt roads and it takes a lot to clear them out. Also they throw a lot of water out the back of the truck in the rain... Not a big deal at all for me. I have 12,000 miles on them so far and have 95%. I rotate them every 3k miles and am running 275/70r18's. I cannot say enough good about them and i will be replacing them with the same tire when there worn out. August 30, 2016
Rated 4 out of 5 by good tire but did not last as long as i had hoped I put these on my 1 ton landscape truck last year and have put just about 30,000 miles on them. They held up really well until about 25k and then wore quickly. I would guess they have about 7500 miles until they are totally done which is not bad, but I am careful about my driving and had expected a little more. I would imagine if these were on a 1/2 ton or smaller vehicle they would be a really good tire. they are not nearly as noisy as I expected them to be whch was a huge plus. I will be switching to at3's for my next set. August 16, 2016
Rated 4 out of 5 by Good tires I had these tires installed in April 2015. I have about 14,000 miles on them now. I have driven them in almost all conditions in the Midwest... rain, snow, gravel, highway, and offroad. Snow traction isnt as good as a tire with smaller tread blocks, but its acceptable. Otherwise the tires have been great. The tread is holding up well. The tread blocks along the outside edges are starting to round off some, but that is to be expected. I am starting to get some small weather checking on the sidewall right around the rim, just outside the bead. I should note that my vehicle is parked outside 24/7. I'm hoping this doesnt get any worse as the tires are only 1.5 years old. August 8, 2016
Rated 5 out of 5 by Love them!!! I bought a set for my Burb that I have put a ton of on and off road miles on... Been running the same set for many years... Know that I've added a plow, these tires are not phased... They have helped me plow through stuff bid diesel trucks were getting stuck in... I'm about to buy my third set of these tires for my newest 2500HD... August 6, 2016
Rated 5 out of 5 by Great on my 4Runner Previously had Duratracs in the stock size but got these in a 285/70/17 for my 5th gen 4runner and couldn't be happier. They ride quieter, smoother, and track better than the old Duratracs did though they're not quite as good in the snow, it's pretty close. I will be buying these again. August 2, 2016
