Cooper AT3 20,000km review: 4×4 product test

The Cooper AT3 LTs have notched up 20,000km.

I have clocked up more than 20,000km on the Cooper AT3s now, which made me realise I’ve been slack performing their second rotation. At their 10K rotation, they showed a measured wear of 1mm; boding well for their longevity. The first rotation also saw me make a pair of locating studs so I could refit the Amarok wheels with much less swearing.

While a big share of the distance travelled so far has been on blacktop, there were some sojourns into the red and rougher outback. The AT3s have been to Lake Gairdner and environs, for Speed Week, the Barrier Ranges for the Outback Challenge, and the drought-ravaged Far West NSW for the Cliffhanger 4WD Event. There’s also been some beach work and track exploration along Australia’s East Coast.

It was at “Cliffy” that the AT3s suffered their first and only (thus far) puncture. In rocky terrain that was tearing apart the competition cars’ tyres, and which was plenty lumpy enough to mask a deflating tyre, my aftermarket TPMS warned of the slow leak and saved the tyre. I remain amazed at where one finds those damned tek screws!

  1. Not a useful review at all: no data for any useful comparisons! The only figure quoted was the 1 mm wear (from what original tread depth???) at 10 K. No % of useage to compare actual versus Cooper’s categorisation for the AT3, and so on.

  2. I used them and the predecessor for many years on my 100 series Cruiser. I did a lot of town running pulling a 3 tonne plant trailer, and some touring with a 2.5 tonne bogie axle caravan, and I regularly exceeded 100,000 km on each pair. I did 462,000 km on the wagon in 18 years, including 2 trips to SA and the Flinders, 2 to Stockton Beach, and a few to the Vic High Country in summer.
    I have never rotated tyres because I cant afford to buy 4 at once. The new ones always go on the front, and the best of the used ones go to the rear. The spare is a new one but it never gets used. I had one puncture from a roofing screw on a building site, in 18 years. I plugged it and forgot about it, so the plug was still in it when the worn out tyre was removed. In my experience, Cooper tyres are outstanding.

  3. I should have added the AT3’s are outstanding for wet and dry roadholding, have surprising off road traction, and are especially good in sand and on corrugations at lower pressures.

  4. Was anyone else expecting an actual review? I didn’t see one useful piece of information in this article. Did the lack of your tyre rotation cause any excessive wear? What was the original tread depth when new compared to 20,000km later? How have the handled in the wet/dry/mud/sand? Are they noisy? Do they high-speed corner well on windy bitumen roads? How do they compare to, say, Mickey Thompsons or other leading brands?
    I could go on, but how about an actual review?

      G’day Darren, we shared this article from another source, and generally it can be difficult to compare honestly because there are so many factors involved. We agree that there should be more robust testing methods and a bit more of a scientific approach to testing. We’ll shake a few trees regarding some of these tyre tests and see if we can get something a bit more useable from anyone…
