The Discoverer A/T3XLT is Cooper's On-Road All-Terrain tire designed for the drivers of pickup trucks, work vehicles and full-size SUVs who need a tire that provides the rugged durability required to keep up with their active lifestyles. Engineered to tackle dirt, gravel, mud and the urban jungle, the Discoverer A/T3XLT combines off-road prowess with agreeable on-road comfort and year-round traction, including in light snow.

Durable-Tread Technology combines a shred-resistant silica compound with the Discoverer A/T3XLT's next-generation all-terrain tread pattern. Cooper's Even Wear Arc Technology optimizes the shape of the footprint for balanced pressure at the contact patch, improving handling and promoting even treadwear. The tread pattern is designed to aid dry traction, while Whisper Grooves between the outboard tread blocks help reduce noise throughout the tire's life. Stone ejector ledges help prevent punctures due to stone drilling, and the Rugged Traction Shoulders feature alternating scoop and cleat lugs and biting edges designed for grip on rock, in thick mud or loose soil. Deep, circumferential channels and wide, lateral notches improve hydroplaning resistance, while multiple zigzag sipes in the independent tread blocks create the biting edges needed for traction in slippery conditions. Snow Groove Technology uses saw-tooth block edges to trap snow in the tread for effective snow-to-snow traction.

The internal construction of the Discoverer A/T3XLT consists of a robust, two-ply polyester casing. A single-ply, nylon reinforcement above two high-strength steel belts further increases durability and handling response, along with providing high-speed stability.

...Road noise doesn't exist, wet and dry performance are exceptional...

I've recommended these to everyone, honestly so grateful I found these tires. Road noise doesn't exist, wet and dry performance are exceptional. Amazing treadwear, what more could you ask for. On a another note I've had some scary curb hits, lifted trucks are not for most parking lots, these sidewalls have been thoroughly vetted. I've had them rotated 3 times, they have towed 8k plus for over 3k miles. They still role perfectly round. I run them at 42 psi, my installer put them at 55 psi.

...Dirt, Mud, Dry & Wet conditions, all performed as you would think great. Never had any issues with Hydroplaning, or issues with under or over steering...

I like to give reviews after many hours and miles driven. I can honestly say that theses tires have never failed me in any situation once so ever. Living in Michigan we have a very diverse weather climate that allows use to drive in all different types of weather situations. In snow the traction was great, I never got stuck even in the deep powder (8-10") and hard packed snow. Breaking on the snow/ice was very controllable and had tons of confident knowing I was going to be able to stop. Dirt, Mud, Dry & Wet conditions, all performed as you would think great. Never had any issues with Hydroplaning, or issues with under or over steering. The road noise is minimal there is some but not much to complain about its very quiet for a LT tire. Towing is great we have a 24' boat and a 32' Travel trailer and the tires have held up really nice at the boat slip in algae covered boat ramps and very stable at highway speeds with a trailer. Overall these tires are probably the single best purchase I have made. All I have to say is do a lot of research before buying your tires, make sure the tire has all of your checkmarks marked off of your needs and wants. Very safe tire, very reliable tire as well.

...I use it everywhere such as in deep snow, on ice, mud, rocks, sand and highway! ... Then when it's time to turn off onto back roads, fire roads, gutted roads, muddy roads, snowstorm/blizzard enhanced travel and more...these tires always come through...

Just blown away by this tire. I use it everywhere such as deep snow, ice, mud, rocks, sand and highway! It is a super quiet tire on the freeway as I even forget I'm driving AT tires at speed. Then when it's time to turn off onto back roads, fire roads, gutted roads, muddy roads, snowstorm/blizzard enhanced travel and more...these tires always come through. I'd say these Discoverer XLT's are way better than any Toyo or similar, let alone the famous KO2 which should only be reserved for rides to starbucks since those both ---- in most conditions, though they look good and aggressive. The Discoverer AT3 XLT's have an aggressive look as well but actually come through for me every time. I am super impressed. I have put this model tire on my brand new 2023 F150 as well and they are perfectly adept for me to conquer everything. People forget that tires make the drive, not all of the technology from the truck manufacturer cuz without great tires for the condition you're in, the super crawl mode or Baja mode won't work worth a crap. Get some great tires and I recommend these if you want to be happy about your choice.

Awesome tire! The aggressive tread pattern gives it the grip it needs to get the job done. I have plowed snow several times this week and the tires don't slide and stick to the road. The best part is the tires are not loud.

These tires are great. The look better and drive better than the factory Firestones. These tires have significant less flex when cornering than the OE tires. They also have great grip. With only 6000 miles I can't really comment on wear, but I haven't noticed any abnormal wear so far. I have no complaints so far with these tires.

...These tires handle very well in the rain and stop on a dime in the wet too...

I've only had these tires for 500 miles and I'm happy to say that Cooper has another new long term customer.
These tires are have a comfortable ride and balanced out perfect. These tires handle very well in the rain and stop on a dime in the wet too.
Soupy and watery mud were no match for the traction sidewalk blocks and deep channels of this tire. It churned through the
mud and came out the hole cleaned out with no rocks in the tread. Haven't gotten to get these into snow yet but if they can
go through soupy mud with ease then I can't imagine how well they'll do in deep snow. If your looking for a change from your regular
BFG all terrain, then these coopers will not disappoint on or off-road

...Tires do a great job aired down and have adequate grip for all of my needs. They also have great on road manners with decent feedback and lateral grip...

Have had these tires for almost two years now and over 42k miles. Main duty as a daily with highway/city driving. My GX460 is also used to tow my track car to events plus the occasional trip to local offroad parks. The tires are not best in class in any category but have been a extremely above average with no real deficits aside from its Snow and Ice performance (not triple peak rated).

Tires do a great job aired down and have adequate grip for all of my needs. They also have great on road manners with decent feedback and lateral grip. Only thing I have noted is the increase in road noise after about 10k miles and beyond. It has slowly gotten louder and louder. With 42k miles I still have over half tread left after doing 5k mile 5 tire rotations. Solid tire and a solid buy.

I like how they feel on the road, with a rather short sidewall they give a firmer ride than our Outback. They seem to be holding up well, but I do rotate the tires on schedule to keep from abnormally wearing the tires out. My wife and I like them and will purchase them again.

...When I saw that the Coopers were 60k treadwear, I found it hard to believe given the aggressive tread pattern, off road category, and previous experience with HD truck tires... I am 40k miles into them with about a 1/4 of that towing a 10K lbs trailer. Looking at what it left of the treads, I have no doubt I am going to make it 60k miles...

OEM were Firestone Destination and barely made it to 30k miles. I had a used Ram 2500 before this that I purchased at 32k miles with the same tires and they were showing the wear bars. When I saw that the Coopers were 60k treadwear, I found it hard to believe given the aggressive tread pattern, off road category, and previous experience with HD truck tires. Also, I was completely expecting them to be way louder on the highway for my daily 30-40 mile commute. Turns out I was wrong on my assumptions. First off, I cannot believe how quiet they are for this tread pattern. Easily as quiet as the original OEM tires despite way more aggressive treads. And the wear so far. I am 40k miles into them with about a 1/4 of that towing a 10K lbs trailer. Looking at what it left of the treads, I have no doubt I am going to make it 60k miles. Simply outstanding. As for performance, I am highly pleased in every category. I've been out in sugar sand beaches and deflated down to 15 psi, I had no problem with traction. Same goes for mud and snow. When it comes time to replace these tires, no doubt going with the same item again.

I just checked my mileage on this set of tires that I purchased in February 2020. I can't believe it but I'm at 65,000 on them and still have plenty of life left. These are on my Toyota Tacoma. I have my alignment locked in place w/ tabs (aside from toe) and I do rotate tires (Back to Front, Front Crossed to Back) each oil change and I do 8-9k mile interval changes. These tires continue to impress. If they ever wear out I'm getting them again. Relatively light compared to others in it's category too.
Wet performance is good. No problems in snow. Dry and off road is great.
