Cooper Discoverer AT3 XLT 20,000 Mile Review

This video is about Cooper Discoverer AT3 XLT and my first 20,000 miles of ownership.

[@joemcmahon8103]

One of the few tires still made in the USA. Support Cooper!!

[@castletrash7770]

Solid review man! I run 33x12.50R15 on my 94 GMC Suburban and have been having a lot of trouble deciding what to get. I am going between these and the BFGoodrich KO2s and I think after hearing this review, I think I want to give the Coopers a go!

[@jewllake]

I love my Coopers AT3. I've had a set on my 4x4 GMC yukon for the last 6 years and they are holding up great after 40K miles. I rotate them ever 15k miles or so. I just purchased a set for my other car, a 2018 Crew cab 4x4 GMC Sierra.

[@deepakramesh11]

i have these tyres in my jeep grand cherokee. they are so amazing on road and quiet as well.amazing all terrain capability as well. tread pattern is also astonishing

[@carsonjeankruse3795]

I’ve 20” AT3 XLT on my 20212 Tahoe and they are Great! I just traveled through adverse winter conditions this weekend! Record snow fall in Great Falls MT over 8” and I had no problem getting around! Had it in 4x4 High and was passing most everybody with no problems or slipping!

[@daveg1318]

Just ordered some for my Tundra. Been wanting some for months, but they were always sold out or unavailable in the size I wanted. Picked up 4 for $1200 tax in 275/65/20. Best value tire on the market in my opinion and amongst the highest rated for consumer satisfaction as well. I love the RWL look. I have a blacked out truck and I think it will look fantastic.

[@jnguitars21]

Great vid! As always! Currently driving a 19 f250 6.7 cc long bed fx4 with the stock tires cant wait to try these cooper on it. Cant stand the stock tires, coopers are great tires. Currently have the at3 4s on f150, at3 xl on excursion and at3 xlt on a gasser 350. All are great tires

I have these on my 2016 Chevy Silverado 2500HD and LOVE them. Quiet, long lasting, they claim 65,000 miles on them and I don't think that will be an issue achieving. My last Coopers lasted that which was the Discoverer AT3. Hands down the best tires I have ever had.

[@AdventuringToday]

I agree! Love these tires. Can't wait to hopefully tackle some snow this winter!

[@bagger2013jm]

How are these holding up as of now?

[@626weekendwarriors9]

For the last 3 years I’ve had the Copper Discover AT tires in 265/60R20 (weight capacity per tire is around 3,100 lbs) on my 2015 2500HD Duramax. I pull a 12k toy hauler during the winter. In June of 2021 while on a long trip the belts separated and a bulge was created on the tread of 1 tire. Sept. 2021 on another road trip 2 other tires of these original 4 had belts break and bulges created on the tread. Not towing anything on both occasions. Do you have the 275/65R20 tires rated at about 3700 lbs per tire and is your truck stock (no lift kit)?

[@TigerPalmer]

Tire Rack has had BFG KO2’s on backorder for months, so I went with these. I have Coopers on all my other vehicles, so it was a no-brainer to try these.

[@g-man2228]

Nice video, the same tires came stock on my 2017 3500 GMC Sierra and I like them. I’m use to the bfg ko’2’s and I think they handle a lot better in the snow. I see your from Missouri as well!!!

[@MaximusD180]

Great Review. I'm about to replace my AT3 LT tires on my Tahoe. I put 75k miles on them so far and just getting a new set. Much better performance than the overrated KO2 at 60% of the price.

I had falkins before, I have been looking at these for about a year now. I dont do anything too crazy, but we do go on vacation in the mountains sometimes and I feel a little more comfortable with a good tire up there.

[@adriangallegos1102]

I just purchased these tires for my Ford F150 275/70/18 two days ago and drove 340 miles on them and the truck felt shaky, I'm assuming squirm was your word, anyway I am glad you said that as I was looking to upgrade suspension and since I still have stock. It would still help but I will wait a bit longer for new suspension. Thanks for the video.

[@jagers4xford471]

Cooper tires rock, it's all I buy. I own cooper STT, Cooper snow and Cooper Discovery ATP, love them all. My next set will be the AT3 XLT to replace the ATP. Thanks for the review

[@AdventuringToday]

Thank you again! I could not agree with you more. Cooper is really stepping it up at a perfect time for domestic manufacturers.

[@noahwright8605]

Out of curiosity, what do you mean by squirming?? This video affirmed my decision on buying these tires at the end of this week, but definitely curious on the squirming. And being an “E” load tire you haven’t seen any premature wear?

[@EverydayOutdoor]

Hey brother, good video! The chunks of material on the sidewall is for airing down off-road, once you let the air out the tire get a bigger foot print and those side lugs can help to dig yourself out

[@joemcmahon8103]

Also for sand driving under normal inflation. The sidewall will help grip in deeper sand.

[@loulehnhoff2637]

I put 305 55 20 at3s and level kit on my Ram due to driving in Wisconsin winters at 3500 miles I rotate when I changed my oil I now have 81000 miles tires still have good tread but I noticed at 60000 miles wet driving abilty decreased and road noise has picked up. Still not down to the ware indicators. Very good tire well worth the xtra money. Getting the xlts 33 12.50 20s tomorrow .

[@henryford2736]

I have the LT not XLT on my F150. Agree with you. These are good tires. I have '15 F150 Lariat 3.5L eco FX4 off road like yours payload is 1745. Only 155 lb less than the F250. Though the F250 had more payload.

[@marc78501]

Nice truck! How has the noise level changed over time?

[@tundrabasser]

How do they ride? I had my truck leveled 2 years ago and it rides pretty stiff but the shop put F rated ridge grapplers on it. I’m running 35x12.5x18 right now but about to swap to 20” wheels and either cooper XLT,s or Toyo AT3’s

[@leopineda74]

Good Video, about to get a set for my 2500 Ram

[@Randy_Savage_ohyeah]

Did you take a fuel mileage hit with these tires? I switched from the Michelins to Goodyear Duratrac and took a 2+ mpg hit. The Duratracs were also a bit squirelly the first thousand miles or so. Like the Duratracs but thinking of giving these a try next go around.

[@billwaterhouse5894]

Thanks for the great review, exactly what I was looking for. I think this will be my next tire (same truck and year). Quick question...the stock Michelin's pick up and throw rocks all over the place on gravel roads, are these better (if you noticed same of course)? Thanks again.

[@AdventuringToday]

Yes..those Michelins did pick up and throw rocks. It drove me crazy...then I put in fender liners and it made a big difference. I thought it was a bit excessive. All tires will do this but the Michelins seems to be in a world of their own. I have not noticed nearly as many rocks picked up or thrown with the Coopers. If the Michelins didn't throw them then they got stuck all over inside the lugs...Coopers seem to be free of rocks most of the time. Hope that helps! I just posted a video on winter performance of the Coopers...check it out! kzbin.info/www/bejne/f3i3fKOAd9ijoqs

[@billwaterhouse5894]

I have a new set of mud terrains in the shed, but been waffling back n forth w these! But in my mind there are some cons i have read about it. I should probably just run my MTs since i already have em, but the coopers would weigh 5 lbs less per tire. Tempting but idk.. im super torn on it. Run what i brung ??

[@jcnme2020]

I have had 3 sets of AT3's I Have Loved every Single mile 345k on my Chevrolet Silverado CREW Cab 4x4 Diesel And I just ordered my first set of AT3's XLT's

[@jwatt95]

You will probably get new tires before I will. I'm curious how these at3 xlt are compared to toyo open country at3. I currently have the toyo at3. So much better then the disappointing at2 toyo I had. So I'm highly impressed with the toyo at3 but may try out these cooper at3 xlt for a comparison and decide the best from there. If anyone has feedback on the comparison between these 2 I would greatly appreciate it. Also love the white lettering I wish toyo did.

[@boatanchorengineworks9005]

How has you opinion of the solid white lettering been for these tires? I think I preferred the previous outlined letters. Its a trivial feature but the BW/OWL/RWL options on tires always change how a truck looks.

[@AdventuringToday]

It is actually still looking really good...when I clean it. I should probably do a video on that...might be a good idea. I like the entire letters being white...the lettering is less susceptible to damage and it seems to stand out a bit more.

[@ThriftyGarage]

What amount of towing do you do with these tires? I have a set of General Grabber ATx that will be needing replaced soon. Looking for a different set that will have better tread life. I pull 7-14k trailers 90% of the time. Mostly around town, occasional freeway but also on gravel and dirt roads. What would you recommend? I'm definitely considering the XLT.

[@justinnash09]

I am really considering these tires for my ram 2500 diesel. Just put the discover at3 4S on my wife's jeep and really like them. One thing I just noticed from watching this video is that the tread on the sidewalls don't match up from one side of the truck to the other. Almost looks like they are directional. Not sure if this could be corrected🤔.

[@AdventuringToday]

Yes...good question...these tires can go any direction. On my truck, when I rotate, I move the back to the front and keep the sides the same then I criss cross the fronts to the back...front left goes to right rear, front right goes to left rear. They are wearing very evenly and I have over 30,000 miles on them now. Happy to hear you like the 4S...considering those as my next tire for my Expedition. Good luck!

[@richard66754]

I have these on my 2006 Titan, and it squirms all over the road when towing a five thousand pound trailer. I have well over 30 k on them. I gave that truck to my son and went and got myself a Titan XD diesel, and am very hesitant about putting these tires on it for towing, because of that squirming you speak of. In the mud, snow, and loose gravel, they are great.

[@AdventuringToday]

I am surprised to hear you were still getting the squirms at 30K. My F250 pulls our 11,500 trailer with no squirm at all. It is rock solid. Could the squirm have been more of the truck...now that you have the XD maybe it handles that trailer better? I bed the engine in your XD is pretty amazing. I need to test drive one of those someday soon! Congrats on the truck.

[@richard66754]

@@AdventuringToday They might perform different on my Titan XD because it has 20" wheels with shorter sidewalls, and is fairly responsive to input from the steering wheel. My older Titan has 18" wheels and the Coopers are kind of balloony feeling. It feels like it's bobbling around on the tires.

[@Icutmetal]

You likely have a weight balance issue with your trailer.

[@bencross5332]

Is everyone sure they don't experience the squirm only on roads with grooved pavement?

[@Kittycat822]

My Mitchlen did the same at 25k and they came stock on my Tundra. I just bought new tires today.

[@user-sv9sf1ns7g]

They are nice looking tires w a sweet sidewall but they are deadly on ice and packed snow tried them on my 18 superduty that is used for commercial plowing along w some very steep residentials. Chains are necessary. I will be switching back to ko2s they are much better and do not require chains

I have a 2016 Ford F350 Club Cab with original tires: Tire Size: LT275/65R20/E Michelin - LTX A/T2 with 39000 miles on the Truck & Tires. A tire just blew on the highway today 6/17/2021 and caused quite a bit of damage to the Rear Fender. It was on the highway and the temp was 105 F and my speed was 70 MPH. Now I don't know what to do I don't trust the other tires on the Truck!!! However, they are supposed to run 60,000 miles. These are supposed to be the best tires you can buy. List price on these tires is over 500.00 each. but now I am thinking of changing Brands! Plus, I have all this damage to my Truck. I do have pictures of everything. Note: There was a very large Explosion when the tire blew without any warning. I was still about 100 miles from Home. So, I put on the spare, stopped at the first stop I could about 2 miles down the road to check the tire pressure on the spare. It only had 45 lbs. of air. So, I added air to the spare and continued home without any more issues.

MAJOR ISSUE with these tires. I've had these tires for 30k miles on my RAM and used it almost identical as you and have absolutely loved them in most conditions. Recently I seen a post about someone having cracking on the sidewall and sure enough I had some deep cracks around most of the tire, aprox. 1/2 inch from the rim bead area, on all 4 of my tires. This could have caused a serious accident in the event of a blowout while pulling my TT. I immediately removed these tires from my truck. Just trying to raise awareness before someone has an accident.

How are they in the snow? How is your mpg’s with them? I lost mpg’s with the BFG’s I put on but great traction. They have gotten noisy with wear however almost to 60 thousand miles with them. Just wondering those points as considering the Coopers

[@ahill7866]

They are amazing in the snow, Love them

[@AdventuringToday]

Thank you for the question. Sorry for the delay. I was traveling out of town for Thanksgiving. I have not had much snow time with these tires as of yet...not enough to form an opinion but I know they are at least as good as the Michelins that came on the truck. MPG's are also at least as good as the Michelins. They are nearly as quiet which is one of the key benefits of the Michelin AT2's. I really am impressed with the looks, off road traction (the few times I've needed it) and the overall ride and quietness of these Coopers. Nothing is offensive about the tires at all. They just do their job reliably and in a way that gets the most performance out of the truck. Just my opinion here...but at anything over 40-45,000 miles I would expect truck tires to start picking up some noise. Some may generate noise sooner. So I wouldn't knock the BFG's for that unless it happened really early. My guess is Coopers will be quieter than the BFG's. Hope that helps.

[@rippinlips1133]

They eat ❄️

[@jackjuby9520]

Well I just put a set of these Coopers on my 08 Tundra. My first impression of them in the 2 snowstorms we have had in the last week is just ok. They are no BFG’s by any means as far as snow traction. My traction control light is on quite a bit. Today’s storm was a lot of slush and they worked okay. I worry what they will be like next winter already. I hope this wasn’t a mistake going with this brand. Time will tell I guess.
