Cooper  Discoverer AT3 LT

I've had this tire on a 2006 Ram 2500 (load range E 10 ply) for the past 60,000 Minnesota miles. They still have a 6/32" of tread, though I run on gravel roads a lot more often than most people. But this is still almost double the miles I got from my last set of tires. Here's my take: These handle really well on dry or wet pavement, have a lot less noise than I was expecting with the aggressive tread pattern, and have just proven to be a solid all around tire - until you get on snow or ice. Then they're bad. I think Cooper must have used a really hard tread compound that sacrifices cold weather performance for longer life. I don't think I'll get these next time because I live in MN, but I would definitely get them again if all my driving was in a warmer climate.

I had these tires put on three months ago. I do mostly city and highway driving but I wanted a heavy duty tire that handled well in all conditions without excessive road noise. These tires were a great find! I have been very pleased with the construction and overall quality of these tires. Cooper did an excellent job designing and testing these tires for truck use.
My previous set of tires on my truck were Firestone Destinations. I was very unhappy with how those performed. Even though those still had plenty of tread left on them, I couldn't trust them after three separate hydroplaning events at very slow speeds. Hydroplaning can easily happen at high speed on any tire, but when you are driving cautiously through heavy rain at slow speeds and you are still hydroplaning, the tires need to go.
These Cooper tires feel like they are bullet proof. American made,10 ply rating, rock removing tread and they weight 50 lbs a piece. Sure, these tires hurt your acceleration a little, but they're grippy, provide good traction and they aren't noisy. I'm hoping to have several years and many many miles out of these tires.

Pros: Quiet, Tough, Heavy, Grippy, American Made in Arkansas

Cons: Ride a little rough, probably due to all of the tread, not a deal breaker for me though
Mileage suffered a little, but it's worth the good handling in bad weather

This is the 2nd set of these tires I've bought. I got just over 70k out of the first set, ran them at 45psi and rotate and balanced them at every oil change. They did so well, I got another set. I have over 40k on them and they still look fairly new and still ride good. They aren't as quiet as the Michelins I had on a previous truck, but for a AT tire, they aren't awful. I mostly drive country roads, gravel roads, some highway, some mud, and through rain and snow when we get any. I will say 99% of the time these tires grip and go, and rarely slip. The most snow Ive ever had them in was about 14 inches and they gripped and we plowed through the snow with hardly any problems. Ice is the only situation wherw these tires aren't great, but that goes for a majority of the tires on the market anyway. If we get ice, I usually don't have to drive anywhere anyway so its ok. Otherwise, they are great tires and I will keep buying them.

I bought my truck used with 13,000 miles with the first owner having put a set of these E-rated Coopers on when new.

I do a significant amount of towing and hauling with my truck...towing an enclosed 20 foot trailer with a classic car inside it at least once every two weeks for my business. At the same time, I live in the city so I don't want the hassle of parking a 3/4 ton or above truck.

Having these E-rated tires on the truck greatly improves the capability of the 1/2 truck...mine isn't even the longer chassis but I can safely haul heavier loads than if the truck were to be equipped with softer sidewall tires.

The benefits of the tire on a 1/2 ton are as follows
-far greater mileage out of the tires...the truck isnt heavy enough to wear harshly on the rubber compound
-far greater capability in terms of hauling and towing..much safer and more stable when they have weight on them
-i find snow performance to be exceptional

The drawbacks are as follows
-the tires are intended for heavier trucks..so the ride is significantly harsher than stock..it wont ride like these new-fangled 1/2 tons do with the otherwise worthless tires they come with "stock"
-Yes they do make more noise than the stock tires...not too much though in my humble opinion.
-again, intended for heavier trucks so wet performance is likely great on a heavier truck but its not great on a 1/2 ton, hydroplaning can happen if you arent paying attention and speeding through deep puddles.
-fuel economy takes a hit of .5 to 1 MPG depending on what kind of driver you are.

I find these drawbacks to be more than acceptable considering the positives described above. I now have over 100,000 miles on my first set and will be buying another set simply because my current set is 7 years old so they are slightly dry rotted from age upon close inspection....at a current 100,368 miles my set has 1/2 tread left, still goes down the road just fine..but its time for a fresh set.

Excellent traction while plowing heavy wet snow. Best traction ever felt in tires for 38+ years on the road. Would definitely recommend these tires to friends and family.

I had the GY wranglers from the factory just so you know what my comparison point is. That being said, there is no comparison to the AT3s. Immediate steering respond improvement, traction in all conditions, and ride comfort especially on rough roads. The only, and I mean only, downside are the inherent changes going from an all-season to an all-terrain tire. A slight drop in fuel efficiency (<1 mpg) and a little more road noise. Stable, dependable, and worth every penny.

Overall a great choice. Quiet ride in all conditions - really noticeable when driving on ground-down highway between these tires and other vehicles. Good traction all around, even when you put it in sport mode and stomp on the gas. Can feel a bit squishy in corners, but never lost traction. Did notice a drop in MPG (about 2) after changing from the stock all-seasons that came with the truck. Treadwear is a bit iffy - have some odd center wear like they were severely overinflated, even though I'm religious about maintaining proper inflation and alignment. However, did a lot of heavy towing recently so I'm going to blame that. Definitely staying with Cooper AT3s.

The best tires I have ever used on any truck I have owned. I have used them year round in N.W. Montana where we get a good amount of snow every winter and they have never left me stranded. Combine that with excellent wet and dry manners and you have a tire that you can count on.

Very comfortable ride for an off road capable tire. Not a lot of miles on them yet, but pleased so far.

These came on my used truck when purchased, presumably new or near new. Ride comfort is above average for an E rated tire. Noise is lower than expected for the tread pattern. On road traits are quite good. Cornering in wet or slick conditions is confident. Gravel roads are handled well. Deep snow or mud is about as good as one can expect. Dropping air pressure makes a huge difference in completing the task at hand. Overall wear has been good when the alignment is good. Will likely buy again based on value for the cost.

Good multi surface tire excellent tread wear so far quiet riding on the highway

This is my second set of tires. My first lasted 45000 ( however they were only rated to 40K at the time ) These are rated to 60K ! must be a new tire compound. I had no issue with them in the Pennsylvania winters before, and expect the same with these. Being a light truck tire - they are not quiet, but not over noisy either. At highway speeds the radio easily drowns out the road noise. I rotate my tires every oil change (5k) and the wear pattern is perfect. AT 45k my last tires would have barely passed state inspection, but they would have passed. I purchased new ones due to a planned vacation trip to Florida ( 2500 miles in a week ) and just wanted the peace of mind. You will be happy with these, I know I am !

Have run this tire on multiple trucks, some studded. Excells in traction on plow truck, great treadlife on F150. Only trade off is mpg drops a little.

Do not purchase these tires in a foreply . Account they wear out extremely fast. Purchase them in a 10 ply load range E. Have had excellent wear traction and abilities to get where they need to go and the tread has war like iron
