Review your Cooper Discoverer ATT SUV >

At 45,000 miles on this set , no punctures , still performing like they are new even when hitting deep puddles , down to under half the tread they had when new , just awesome tyres.

I use these tyres on my suzuki grand vitara, I am 100% happy with these tyres in all weather conditions. These tyres give absolute comfort and control with zero road noise, if your looking for performance tyres then look no further, they are great in the dry and the wet, snow and ice. I use these tyres off road as well and they are great off road, I go places were most 4x4 drivers don't dare to venture and I have never been stuck with these tyres.

#Cooper #Discoverer #ATT (2.3 ATM) - Hi all, we had the privilege to start testing the new Cooper ATTs. Our colleagues pressured us to release a video so I only had 3 days of solo testing. The overall testing will continue in the next 3-4 months, versus included, so stay tuned. At the end of the video you will also find the first AT chart temporary grades for this new tire. Some grades are purely speculative from design analysis experience, as we had not tested yet the mud, snow, etc.
The tire impressed me with its fuel consumption, in city and outside I had around 1 liter in fuel consumption gain, it is also exceptionally quiet, medium priced summer tire levels. It has no vibrations at high speeds and keeps a good stable road direction (when you reduce hand input). Lateral grip is insanely good and this will not only be an asset on asphalt but in off-road especially when you have to Spiderman your car, driving at high speed on gravel or to avoid lateral slides on inclined hills.
On the off-road dust, gravel and dry grass the tires performed well. I would say that grass and gravel are the first surfaces to be traded off for high speed on asphalt features. As on any tire, it is all about balance and trade-offs. For a tire that is manufactured in China, it shows how much they have advanced with western help. We are biased against Chinese made tires, but in this case, we didn’t find anything to complain… yet!
Compared with AT34S, you have 10-15%: less traction, stopping power but the tires are significant less fuel consumption, less noise and a bit more lateral grip. We also suspect that the ATT will perform better in mud than the grades we listed. More testing will come for the ATTs, for now though they have our appreciation for their price versus performance offer.
Photo details explained:
1. Interesting X like Sipe, an unusual design for the edge blocks. Design to offer resistance, control and stability at high speeds turns.
2. Whisper grooves, split this time, they provide a sound barrier. Don’t worry for water elimination, that’s not lateral here but behind the tire.
3. Stone ejector ledges and engineered groove shapes. They also prevent the blocks from being ripped-of or getting deep splits.
4. Cut block edges to prevent damage ruptures. This also helps with the mud release.
5. Asynchronous central aquavac channels, for netter mud and snow traction. Similar edges to 4 but doubled down in 2 parts for surface higher risk of the block.
6. Inclined block external edges to allow faster mud release and a higher water evacuation volume.
7. Small overlapped central block column interlock, this ensures a quitter ride and constant traction control performance at high speed.
8. High Silica content compound, summer biased chemically. Provides decent cut and good chip performance and best-in-class tread wear and traction. We expect ATT to be chemically a bit stronger than 4S.
9. Also 10 – same block edge cut, this will allow for faster mud release, especially mud mixed with grass.
11. Lateral block enhancements and surface enlargement for better lateral protection and grip in direction changes in off-road.
12. Small shoulder size differences, for lateral grip. They are smaller than usual on other ATs to ensure high speed direction change stability.
13. Deep vertical lateral sipes. A small overkill design feature that shows the fact that the tire was tested and designed with the help of machine learning. You can see things that only an AI will do.
14. Extra lateral protection for high spin in rocks.
15. Grip and structural small lines, for lateral low speed rocks grip.
16. Raised curb bars, designed to give extra protection in going over rocks and spinning the rites while also in a tight direction turn.
