Cooper Discoverer A/T3 4S

I bought these tires in December 2019 for my 03 GMC Sierra and thought that they did a great job. I have never had any trouble with the grip on wet or dry ground. I have also taken them on gravel roads, offroad through woods and pastures. I have never gotten stuck or had a problem with them anywhere. I was actually going to get a new pair of these tires because I liked them so much but Cooper has come out with the Discoverer Road and Trail AT tire that is supposed to be the updated version of this tire so I am purchasing that one instead. The tires lasted for just over 60,000 miles and I probably could have gotten a few thousand more miles out of them if I had rotated them a little more frequently.

Overall I am very happy with this tire and would have purchased again.

Tires are poor quality and the company behind them is inadequate in Europe. Cooper has a recall on these tires. I have had to get them repaired before. I would be entitled to a recall. At first I was told I could replace the tires. After that I never heard from them again. They don't respond to emails. Never again Cooper.

Use many off-road. Exceptional grip in sand. Several friends have Cooper tires on heavier vehicles. They recommend Cooper tires to me because of all around performance. So far very satisfied.

General overview:
Good for on road driving, logging road mains/light off-roading & construction sites. Good fuel economy & comfort/ handling. Wore not to my liking most likely due to more intense off road driving.


New on road:
Very good in dry conditions.
Quite good in snow and wet.
Handling is solid and ride is decently comfortable as it is an SL not an E rated tire.
Pretty good fuel economy, it is 41lbs so not heavy.


Worn in on road:
Very good in dry conditions.
Still quite good in snow, and wet grip, but wet braking performance has diminished more than I would like.
Handling still feels very good.
Fuel economy still good.
Tires wore poorly most likely due to my more intense off roading. Tread lugs starting to chip and round but are still very durable, no punctures.


Offroad overview:
They do preform very well off road in loose steep climbs and fresh packed snow climbs when airing down. I am quite surprised as the tread pattern does not look very aggressive.
Very durable even being an SL rated tire. Never had a puncture even while going off road with sharper rocks with airing down a little.

Overall quite happy with them and would buy again if I did not do as intense of off roading as I do now. But they are not the tires for me anymore.

Had these fitted to my Nissan Pathfinder where my usage is 90% on road & 10% off. My on road is quite sedate as I stopped being a boy racer years ago. Nitrogen filled and rotated as per Coopers requirement every 8000kms to maintain their 100,000kms mileage guarantee. One of them shredded at 15,000kms having never been off road. After a bit of heated discussion with Cooper South Africa who were only going to contribute 85% of the cost, they eventually contributed the full 100%. I've just had to replace all four after only 45,0000kms as they were down to the tread wear bars. ~ not even HALF of the claimed mileage. The guarantee isn't worth the paper it's written on and quite were Cooper pluck this mileage figure from is beyond me. Would I buy them again? Certainly not. Can I recommend them? No.

I have had Coopers before, with great results. So far, these are exceeding my expectations. They are quiet on the road, and give me a feeling of confidence as I use them. Great price for the value you get.

I bought theese tires especially for snow after a long research. I was not disapointed as they behave like a winter tire bought in the snow and ice. I can't say much regarding wear as I only driven them 10k - there's hardly any wear visible by now. In the dry: it's an AT tire on a Merc X Class, they grip well on and off road. Road noise it's not bad, just not as good as a summer tire. Overall I am very satisfied with the performance in winter conditions, comparing with Goodyear Wrangler Duratrac.

I had these fitted very soon after getting my truck as the original Continentals had very little traction on the rear wheels on wet roads and mud. The Coopers have been excellent tires. Handling isn't as good as with the original Continental tires, but that's expected as the Coopers are all terrain tires with a much more chunky tread. This doesn't bother me as I drive a truck, not a sports car! Performance on both dry and wet roads is excellent. Performance off road is also superb and they really do allow the truck to go anywhere. Tire wear is very good. I've done 16,000 miles on them and they've hardly worn at all.

Mounted these on my All New (2020) Jimny and it exceeded my expectations! Grip is excellent both in dry and wet conditions. Road noise is almost non existent (same if not better than the stock Dunlop Grantrek AT20) and there seems to be no negative impact on my fuel economy despite being wider and bigger (although I am a light footed driver). I get better handling on this especially when cornering primarily because it is much wider than the stock 195/80/r15 Dunlop's. I will surely buy these tires again in the future! I only clocked in about 2000 kms on this so it is still not showing any visible signs of wear.

I bought these on promotion for about 1/3 less than they go for now.
Pros:
A handsome tire with good grip in all conditions. Unphased by heavy rain on the highway. Particularly amazing grip in deep snow in 4H or 4L. With 8" snow I was comfortably smashing up steep hills, stopping controlled and quickly, and VERY predictably 4 wheel drifting in the snow. Very good at expelling mud or snow from getting packed in the tread. Noise from tire is hardly noticeable compared to other tires in the category. Capable on and off road with an amazing 65,000 mile warranty.

Cons:
MPG noticably decreased; my average mpg fell from ~18.5 to ~17 mpg in the past year. The tires squeal on concrete roads in wet conditions before they have warmed up. Pebbles stay wedged in between the tread and make clicking noises until the noise stops on the highway and some poor sod behind you got a rock chip. Tire feedback feels numb, but that blame can be shared with my 20 yr old suspension on a 4500# Nissan dinosaur. Also, the price skyrocketed after the positive reviews rolled in.

TL;DR These are class leading tires that punch above their, and their manufacturer's weight. Cooper marketing was spot on for the SUV driver that mostly keeps to the highway, but needs uncompromising off-road performance when duty calls. At the current $156/ea USD price online, I'd shop around or wait for a rebate. When first released I got the price down to ~$100/ea USD with a rebate.
