Cooper Discoverer AT3 LT | 10,000 mile - 1 Year Review
Вставка
- Опубліковано 1 сер 2024
- This is a quick review of the Cooper Discoverer AT3 LT (ATs). I've had these for about one year and put on only 10,000 miles due to 2020 being crazy. Previously I had the Cooper Discoverer S/T Maxx hybrid tires in the same exact 275/70-R17 size and E-rating. These tires have been great for me thus far and suit my needs perfectly. I really like what Cooper is doing with their tire technology, but there are still many great offerings from BF-Goodrich, Toyo, General Grabber, etc. I love me some mud terrain tires, but I had to be honest about my needs and get an all-terrain.

Finally, a video review worth watching. Thanks
Great review I have the AT3 XL my taco love them. Perform flawlessly in all conditions on and off road.
Have the XLT3 on my Ford F250 6.7 diesel FX4. As quiet and smooth as my Michelin AT2. Did took 1,000 miles to settle down. No noise or roar. Really good in the dry and sure footed in rain. In the past 2 weeks we've had more than our usual snow. We've gotten a foot of snow and I've crunched around in 4x4 with no problem. I deep fluffy snow just a bit of wheel spin clears them out. Have not been in deep mud and only ran through graded trails but no complaints there. Good mileage and wear.
I'm deciding between the Michelins and Coopers. Have you noticed any change in fuel efficiency between the two?
Thnks for the review makes me confident with my decision to go for it, i really like to have a quieter AT tire.
Appreciate the details on both sets of tires and by someone who uses their vehicle for a variety of uses and the reality and practicality of what works and why
Thanks
And … “crazy DC drivers”
…. Flak jacket ?
Northern va / dc traffic is a different type of mayhem
I’ve ran both those tires on my Tacoma. I’ve noticed more chipping on the at3 lt. solid review/ comparison.
Im thinking the same tire for my tacoma as well
great review. thank you
I've run all three Coopers. The AT3 is my favorite all around tire.
Great to know...
I had the AT3. Nice tires but Tirerack's winter test has the Cooper well.above it. The 4s. That's why I switched.
@@joeguglielmo1484 Yes the Cooper AT3 4s is winter rated. It has a softer compound to stay flexible in cold weather plus I think it has more sipping.
@rudedog062 Agreed. Definitely more siping. The Wildpeak was a nice tire. I liked it. But this time I wanted to try the Cooper.
Great point: need vs want , I have been flipping back and forth between a mud tire and a all terrain tire. Cooper AT3 XLT is on my short list. For my 1/2 ton diesel
Yes, lots of people love the mui Macho mud tires but they are noisy, rough, actually had less traction in pavement and in the rain and wear much faster. May be ok when you're young, but it get old paying $1,800 for 4 corners every 2 years because they wear loke butter.
I use’em out here in the AZ rocks and desert. Great Tires
Good to hear for some reason there's no videos of offroad test lol
Thanks bro, great info!!!
So these r good for Los Angeles weather. Not much off road action...?
Put the 4S's on the wife's 1500 Ram last fall, very impressed with there ability in ice and snow. I'm putting them on my 2500 Ram crew cab Long box diesel this week. We'll see how they do towing a 14000lb fifth wheel. I'm currently running Goodyear duratracs and the sidewalls are way to soft for towing. To much Tire roll and sway.
How did they do for towing? Im getting the at3 xlt on monday and will be towing around 10k
@@Subscribe4luck.
Sorry for the late reply was away in northern Ontario which gave these tires a good test. Towed my fifth wheel on everything from pavement to dirt roads and these tires performed flawlessly.wet and dry conditions. Handled well at 120 km/h on the highway.
@@donwoodcock7696 how well are they wearing pulling those heavy loads?
@@ThomperBeThompin very happy with these tires, they show very little wear, after 6 months of heavy towing.
I had a set of them did as good ad a m t in the south Alabama black muck and slick red clay roads awesome tires
Sure
Thanks for the information. You mentioned your Four Runner had a rear locker. Did you add the locker or is that factory equipment?
This is the factory electronic locker, certain trims have it
tire rack has the 4s listed with a higher load rating than the LT in the 260-75 17 size... does that sound right?
That doesn't sound right to me.
Thank you for the review, what size of rims are you using? 17 x 9?
These ones are 17x8 with a -10 mm offset
Good info, thanks for sharing. If you could give us an update on your experience with these tires and if you're still running them. I'm about ready to put new tires on my 4Runner. Currently running KO2's E rated. They've been good tires overall. I have about 44k miles on them, decent amount of tread left but the wet traction is starting to suffer at this point, and I don't like to run tires down too low. I'm in the DC area as well, rarely off-road and value good on road manners and wet traction. These seem like they'd be a good option. I was also looking at the Falken Wildpeak's.
I actually traded this truck in with only about 20,000 mi on those tires. They were flawless the whole time. I ended up getting another 5th gen 4Runner and put the Cooper discover AT3s 4S on. I've had these on for about 25,000 mi and will absolutely be getting another set when they are done. I anticipate getting 50,000 mi out of them and I too do not run them down to the wear bars.
So the KO2s aren't that good in rainy conditions huh,I better just get these Coopers AT3s for my Sequoia 275-65-18 and call it a day,they seem to be great overall tires especially for rain and snow...
Thank you for sharing your thoughts. I currently run the AT3 XLT on my Land Cruiser. I am very happy with them. I am now thinking on changing my tires on my, other truck, the FJ Cruiser. I'm thinking on going with the S/T Maxx. However, after hearing your thoughts on it and realizing we probably drive on similar situations (90% on-road, 10% off-road, importance to wet traction), I might stick with AT3's again. Is there anything else that could sway me back to the S/T Maxx over the AT3 LT or XLT?
It really depends on your situation. Like I said I've got a winch, Max tracks, and I'm usually always off-roading with another vehicle so I'm not too concerned about getting stuck on any obstacles or anything. That makes my need for a hybrid tire or mud tire even less so. The only reason I would consider going with the hybrid tire is for the slightly better puncture resistance in the sidewall and the slightly better traction in the slippery stuff. I will likely continue choosing between all terrains for my daily driver / weekend warrior vehicle, and mud terrains for any dedicated off-roader. Good luck in your choice man, I know it's a tough one because tires are really expensive!
What air pressure are you running ?
@@backinthedaybmx7940 43 psi
That’s why I’m going with the AT3, I’ll be doing only 10% off-roading also and where I live it rains a lot. So wet traction is very important to me. I heard the AT3’s have one of the best wet traction for an all terrain tire. And you could tell by looking at their tread pattern it’s good for wet weather.
I have been stuck between these tires, General Atx and Falken AT3W. Coming from a Duratrac for Colorado winters, would you recommend the Coopers in deep snow?
as long as you have a set of maxtrax they will be pretty good and deep snow of several inches. That said, they will not chew through seriously deep snow like a mud tire, or even a fresh duratrac would.
How many miles did you get out of your duratracs?
Who makes Duratrac and exactly which model???
@@mercedesbenzs600bash Live under a rock? Google broken?
Thanks for the video. I’m leaning towards the XL for my f 150 over the lease aggressive coolers. The ones your brother has. Is the ride quality a little stiffer more harsh on the XL’s compared to your brothers? I don’t need the extra load capacity but I do like the look of the XL’s better. Thanks for the video.
I would highly recommend going with the 4S. The XL's definitely look a little bit better, but because they're an e-rating they are much heavier and stiffer. The extra weight will zap a little bit of power on acceleration and fuel economy because you're turning those heavier tires. And being stiffer they contribute to a rougher ride. Additionally, the 4S has more siping and a better tread compound for wet and cold weather. All that said, I think either the 4s or LTs or XLTs will be great and I wouldn't hesitate to buy them again. For my new daily driver, a tundra, I'll be sticking with the 4S's since I will not be doing any crazy off-roading.
@@ThomperBeThompin - I appreciate the feedback. Thank you very much
Were you able to find the listing of what sizes have the 3PMSF rating somewhere? I'm looking at them in LT265/60R18 for my incoming GX 460 and can't seem to find that information anywhere.
I swear I remember looking at a chart online that showed it, but I'm failing to find that same chart at least on their mobile site. You might want to check from an actual computer and if that doesn't work you might have to call.
@@ThomperBeThompin I couldn't find it so I did call and was told at least the size I need has the 3PMSF rating so that's good.
Thanks for the update dude 👍...I assume there’s a noticeable mpg and acceleration improvement over the ST MAXX?
Honestly there is not. I was quite surprised to find essentially no difference in MPGs. These are still pretty heavy and are the same exact size so that might have something to do with it. The biggest hit to my MPGs is aerodynamics from the roof rack and front bumper, so finding slight differences in MPGs due to tires is tough.
@@ThomperBeThompin wow,I was definitely expecting better mpg than your heavy Maxx tires...interesting...this is the same size I’m currently in the market for (FJ Cruiser,mostly highway miles)... I really like your tire reviews,keep up the good work dude
Savings of 28lbs total tire weight won't net a noticeable amount of fuel savings. But it's an LT so what do we expect?
I was gonna go with the 4s but now on torn on it looking at the Lt. How much did it drop the mpg.
Same question here. I keep popping tires when I off-road on rocks in my tacoma … so I am thinking LT load C versus the 4s with SL load
Great information my man its really appreciated,I'm in New Jersey,I do no off roading,i drive an 08 Toyota Sequoia Limited 275-65-18 with over 230,000 miles and I'm really only concerned about cornering,heavy rain and snowy,icy conditions and this sounds like it's really a great tire for those conditions I just mentioned or do i need a heavier tire because of the truck size,what do you really think or should I buy BFG KO2s,Toyo Open Country 2s,Nitto Terra Grappler???
I think all the half ton trucks that are sold brand new have stock tires that are regular passenger rated for load. You can probably get away with the AT3 4S. That's what I have on my current 4Runner and I love them even more than these! All those other tires you mentioned sure are great, but I would still prefer these based on their silica tread compound, and ample siping.
@@ThomperBeThompin Much appreciated my man..
I live in Colorado, driving Ford F-150 4x4. Currently on Falken Wildpeak A/T3W All-Terrain that needs to be changed. I love their look and the price, however with regular rotation I only got about 40-45K out of them, mostly city-highway driving. They are also not doing very well on sow, they're okay.... Looking in to Cooper A/T 4S, curious how do they do in snow and ice specifically ? Thank you
Since evaluating a tire's performance in snow is very subjective, all I can really say is that I'm happy with them in the snowy, slushy, winter conditions and feel fully confident running them for a full winter. I am pretty good about adjusting my driving style to suit the conditions, but I also grew up in Buffalo where it snows a lot - I'd feel comfortable running these there too. Obviously they are not a proper snow tire, but they do well.
@@ThomperBeThompin thank you
I know I'm a lil late to the party, but how do think they would do in SAND. The loose sugar like stuff?
Better than a mud terrain would. Probably on par with some ATs. So, decent?
How do you you think a C load version of this tire will hold up off road?
Honestly probably fine. There's tons of regular passenger tires and C load tires out there cruisin the trails. I think properly airing down, good line choice, and good spotting is more important.
Just curious, I know that the 83 is coming to LT C rating how come you went for the E? I had the XLTs in the E rating and it was a ROUGH ride
If I remember correctly, the e-rating was the only one available for that size at the time. I could be wrong though. I can't quite remember. Also, in my opinion, there's not too much difference in stiffness from the seat of the pants feel between a c rated and e-rated tire. They are both light truck tires designed for heavier duty and higher capacities. Now the difference between a c load and a passenger tire is probably pretty noticeable. I honestly didn't think these were too stiff for this setup. That said, not as comfortable as a passenger tire for sure.
@@ThomperBeThompin as badass as the xlts looked I had to keep tire pressure significantly lower to make the ride somewhat comfortable. The C rated in on now feel like night and day. Then again I had major back surgery so I feel the slightest difference in anything now. Thanks for the reply, stay safe bud
Hi, can you please tell me the difference between this Cooper Discoverer AT3 and the Cooper Evolution ATT ?
I'm not 100% sure, but they appear to be very similar to the Cooper Discoverer ATP lineup that is sold exclusively through Direct Tire outlets. I imagine these are similar and allow for the vender to have an exclusive tire from Cooper (and so they don't have to worry about price matching anyone else!). Looks like a licensing thing. Probably a great tire and on par with Cooper's ATP sold at DT.
Can you please tell me if the other side of these tires have the black lettering? Thank you!
Yes they do. Most tires these days come with both options, white letters and all black
@@ThomperBeThompin thank you
I experienced the same confusion in regard to the snowflake extreme weather rating.
I purchased the xlt in 295/75/R16 and they did NOT have the three peak symbol. I have definitely seen picture were or did so not sure what the deal is with that.
I just bought mine so can’t say much as to longevity but holy cow do they grip wet slushy pavement well. Smooth quite ride. Felt like I had a new suspension put in.
I'm certainly no expert on the snowflake rating and how that's achieved, but from a little bit of research it seems like it could be one of those things companies have to actively go out and pursue through testing paid out of their own pocket and such. So just because the tire lacks a snowflake symbol may not mean it isnt great in the snow. I mean, I would highly doubt the compound is any different between the sizes and the XLT tire. But I'm not positive about that, I know there's minute differences and speed ratings and stuff so I wonder if that plays into it.
I believe the tire width needs to be 12 inches or less
3 peak mountain rating only up to size 285/75/17 I think read it on there site somewhere
You said your brother has the AT3 4 s I am looking at those or Canadian Tires motor master x-trail eliminators which Cooper designed for Canadian Tire with rebate on the Coopers these tires are both the same price. I'd be interested to see what which one you would pick, but I know I won't be let down with the a t 4 S' s, you mentioned the silicone that goes through those to make them more grippy, I have a Hyundai Santa Fe 2009 3.3 all wheel drive always had all terrain tires on them, last year switch to a dedicated snow tire was good on flat icy snowy surfaces but terrible cushioning as a passenger tire in the back roads and alleys, so I'm switching back to an at that has the mountain peaks snowflake, and I've looked at Cooper's the last 4 years and I'm excited to see how they do. I don't know if you want to do a video on the a t three 4S Coopers, awesome video, didn't mind the length of it most videos are a lot of action, just having your vehicle parked right there with the center of attention on the tire able to talk a little bit more about it it was different I didn't mind it, cheers for now.
Hey, thank you! I'm actually running the 4s right now! I love it. The only reason I'd get the LT again is if I needed the load range capacity. The 4s has been fantastic after 30k miles for me. I will be buying another set after these.
@@ThomperBeThompin how much off road in those 4s?
@@pronto9722 I've only done a little bit of basic off-roading with these tires so far. I'm very happy with their performance but they obviously don't do well in the mud at all.
I had the STmaxx and i am a bit dissapointed with them. I you get a punkture; by the time you get to a stand still, the side walls have cracks .
What PSI do you run off road
Depends quite a bit. Usually around 15. I've run as low as 12. 15-18 is pretty good.
Have you still got them fitted? How many miles now?
I do not. I actually sold this 4runner. They had about 20k on them and still looked great. I have recently tried the 4S' on a different vehicle and loved them. Will get another set of these for my tundra in the next year or two. I'm still very happy with this lineup of discoverer AT3 tires
@@ThomperBeThompin thank you for the response. Knowing you’d buy them again is a win for me 👍🏽
What psi do you run them for city driving?
Right around 35 cold. They heat up to 38-40 on the highway.
@@ThomperBeThompin Thanks!
I've yet to wear out a set of Cooper tires before I wore out the vehicle(s) they were mounted on. In fact one dealer admitted he was giving me a better (money wise) trade in BECAUSE of the Cooper tires on the beat the hell up Ford F150 I was trading in.
I am literally in the waiting room at a tire shop getting some Cooper discoverer at3's installed on the brand new 4Runner I just traded in for! These tires are fantastic
What psi do you run?
Sorry for the late reply. I think I was running about 37 give or take a couple
I just got these to replace Michelins that came with the truck.
Ford F- 150?
@@angryagain68 No, a Colorado. They may not have been factory, I bought it used with 20k miles on it and the tires were like new. It's got 80k now.
@@ericnortan9012 Ah. I just noticed that most f-150's came stock with Michelins too.
How do these compared to your older michelins?
@@ThomperBeThompin the michelins were great tires for the northern michigan roads in all conditions. Not great on the trails but decent. So far the coopers are great. We had a couple of ice/snow/rain days and they did great. The tread is a bit more aggressive so the ride isn't quite as smooth, but nothing really noticable. I haven't really tested them off road yet but trout camp is in 3 weeks, they will get quite a workout that week. The coopers look cooler and i think will do better on the trails. The michelins lasted forever and are excellent on the road, decent on the trails.
Do they chuck Rocks on gravel
Not at all so far.
They do throw rocks like my Michelin AT2s. I carry a long nose curved end pliers and they are perfect for pulling rocks out if the tread.
What year is your 4Runner?
This one is a 2014
@@ThomperBeThompin are these load range C or E?
@@jaymoar3561 these are E, but I think you can get a C in certain sizes
All tires have wet weather ⛈️☔traction rating. There should be AA or A rating on the side wall. AA is best A , B, C. Coopers also give you best value for $ 💰
