COOPER Discoverer AT3

What's up gang, I just bought & had these tires installed on my 2013 WK2 Laredo . They are everything the reviews say they are. For an All-Terrain tire they are very quiet on-road & have an agressive enough tread pattern for off-road work. I am heading to deer camp this weekend where it will be rainy & muddy. I live in PA, so no hunting on Sunday. Sunday will be trail day!!!! Most of the forest roads are ok, but some have no service . Can't wait to try out my new shoes.

Re: COOPER Discoverer AT3

Greetings,

The A/T3's are an excellent tire. Cooper brought them up to another level with A/TW:

For P sizes:

Cooper Tire & Rubber Company - Discoverer A/TW„

For LT sizes:

Cooper Tire & Rubber Company - Discoverer A/TW„

Note: Currently their is no standard sizes for the JGC.


This was a result of the consumer base asking for an even better winter performance. Their were some here that had the A/T3's and complained about problems with mixed ice conditions. The A/TW has a bit softer compound and additional and revised siping design. While the A/T3's are a little hard for off road action.

Best for now.

Re: COOPER Discoverer AT3

1stJeepGC, are you saying the AT3 is intentionally hard for off-road traction, and that is a good thing, or it is too hard for maximum off-road traction and now there is no reason to buy the AT3? Essentially that all AT3 buyers should now just consider the ATW since it is superior in all scenarios?

Glad to see this thread. My OEMs are wearing out and am looking at either the AT3 or the ATW, primarily driven by the Expedition Portal reviews.

Greetings,

IMHO, their are 3 scenarios or categories in dealing with AT tires. AT tires today is really a comprise. I do not think any AT out their right now is superior in all scenarios.

Using the Coopers as the example for 2 out of 3 scenarios.
SCENARIO # 1: If somebody is more concerned of using an AT tire with the priority for maximum winter driving and still needs the AT for the other 3 seasons, then I would look at the A/TW.
OR:
SCENARIO # 2: If somebody is more concerned about going off road on hard trails that you do not need the heavy duties and maintaining highway performance with winter capabilities, then I would look at the A/T3.
Remember: AT tires are not dedicated winter tires. The heavy duty ones, such as the GY Duratrac or the Nitto EXO Grappler that allow the use of studs is now consider a dedicated winter tire. I have been told that the BFG KO2's are considered a grey area since they have no provisions for studs. These tires is what I consider Scenario # 3.

In order to get the best winter performance, a softer tire compound will give you the best possible traction as the temps get lower. IMHO, this could be a problem with a rocky trail or an abusive one. You can wear the tire down much quicker and/or have a chunk removed off the tire block.

To answer your question, do you really need AT tires? If you do, than see if the above scenarios work for you. Besides Cooper, you got BFG, Nitto, GY and of course my favorite, Nokian as few examples. They will all come up here in the forum when you search.

Hope this helps.

Best for now.

Re: COOPER Discoverer AT3

How did they do on the trails? I'm wavering between stock size or up one to 255/70r17 in either the AT3 or the ATW. I have a 2014 Laredo E with ORA1 and Tow package.

They were fine...good traction in the mud and soft stuff. I have a Laredo E w/ the tow package and ORA 1 as well ..I was thinking of going with P255/75-17 but decided not too.From what I've seen on the forums that size will fit.good luck with whatever you choose.

Merry Christmas
