Rated 3 out of 5 by from 2014 Ram 3500 Dually Squishy feeling when new. Went away after a couple thousand miles. Work truck hooked to trailer 90% of time. Got about 24000 out of them. 4 are at the wear bars, 2 are past. Rotated constantly. Same tires on my wife's 1500, she's got 30k on them and they still have 90% of their tread...? So I'm guessing great for light duty trucks or non working trucks, but if you have a HD truck your better off getting something different. Going to At3 seeing if can capitalize on the mileage warranty

Rated 3 out of 5 by from Great tire except in the snow and ice Have had these tires on my F250 for almost 3 years now and overall they are a decent tire. The off-road capability of these tires is good, they definitely bite hard on rough roads, mud, and loose dirt. They also have an aggressive sidewall with a fair amount of bite as well. Towing with them is decent, I have not had any problems as far as instability, even when towing over 10,000lbs. Wet traction is fairly good. They also wear very well as long as your alignment is set for good tire wear and you rotate them often. The worst part about these tires is their performance in the winter on the snow and ice. Winter traction is awful, these tires have very little sipping and although they can be studded, who would stud an A/T tire just to have the studs removed in the spring and not be able to restud them again down the road?? Iv tried running them down to 35psi in the winter and the traction is no different, even with 500lbs in the box, they are still horrible in the winter. They dig well when there is a lot of snow to drive through, but once you work your way down to the ice, good luck. Overall they are a decent tire, more sipping I think would help the snow and ice traction. These tires also hold and throw stones like crazy! Definitely a good off-road aggressive all terrain tire, but not great on ice and hard pack snow. For the price you pay, there are better tires out there for the same kind of money. These are a very capable tire, just not so much in the winter months.

Rated 4 out of 5 by from 2014 Ram 2500 Bought these tires back in March of last year, (16) by far tires have held up pretty good, used them for 50/50 towing daily driver so they do see a load mostly every weekend, and driving on highway daily, overall good tire but I do feel when road is wet they do tend to give some lift bit of slip when you give it some gas, towing they felt good, towing dump trailer and skid steer they feel solid, boat ramp they will get you from down the ramp to the top, have about 25k on them and will need replacing in about about a month going to run them down to the bottom to see how far I can wear them down, overall solid tire just personal preference on looks, and driving conditions.

Rated 5 out of 5 by from Awesome wear, great all terrain tire I put these tires in 295/70 18 on my 2010 Tundra after the Toyo Open Country A/Ts wore out in just over 15000 miles and 1 year later. I have had these on my truck for almost 3 years now and going on 60000 miles now and still have more tread on them than the Toyos had on them new. I have had these tires in the mud, snow, gravel, wet pavement and lots of dry Arizona pavement and these perform great. Not perfect on every surface, but what tire is? I have sold alot of friends on Cooper tires because of this set and will definitely buy these again when the time comes.

Rated 3 out of 5 by from Great off the road, really hurts the MPG though I purchased my Cooper S-T Maxx (285/75/R17) tires as a replacement for BFG Long Trail T/A (265 series) tires. I've had mixed results thus far, at approx. 5,900 miles. Good- -They wear well -They're stable towing, even at max inflation and tow weights (8-10T) -They work well in dirt and, of course, mud -They look GREAT Bad: -Very difficult to balance -Bouncy ride (as compared to Good Year MTR) -Reduced my MPG by 4-5mpg, on average -Wet performance is poor -Snow performance is very poor -Interestingly enough, they are "squirmy" when unloaded and reduce the confidence I have in my truck's handling Overall, if you primarily drive on dirt roads or off-road, these will likely serve you very well. I primarily use my rig on road, 70/30 mixed hi-way and city driving. For me, these tires do not work as well as the previous tires. I recommend these, as I believe they are better suited for dirt than pavement.

Rated 2 out of 5 by from not for 3/4 ton and up I have ran two sets of these one in 265/75/16 and one in 285/75/16. The 285's got 26000 miles and the 265's got 21000 miles on an 06 2500hd GMC W/T 6.0 nothing exciting. i don't haul a load often, 3-4 times a year all under 7500lbs. All that said i think they are a great looking tire not very loud after 5k miles and they do perform as they should just not for very long on heavier trucks.
