Cooper Discoverer ST MAXX Owner Reviews

Review this tire

What owners say summarised from 6 reviews

Owners most often describe the Cooper Discoverer ST MAXX as a useful balance between road use and off-road capability, with favorable comments on resistance to punctures and rock damage. The six reviews from five owners average 77.8%, with four positive and two neutral scores. Dry grip receives praise, while wet grip is split between one favorable account and one criticism, particularly in cold, greasy conditions. One longer-use owner finds the ride very harsh, but this is not a recurring complaint. Two-thirds of the reviews are initial impressions, so later-use wear is encouraging but too limited to establish a typical lifespan, and the repeat owner remains positive without showing a clear ageing sequence.

Great tires, seemingly impervious to sidewall attacks by sharp rocks, but the ride is truly terrible - they feel like solids.

A very off road capable, on road friendly tire... Its a hybrid or rugged construction, sitting between an AT and a MT... Tire choice is always a compromise, but the Cooper ST Maxx tread a fine line and provide a good balance....

Had the Cooper ST MAXX tires 6 months, lasting very well, great in the dry, not so great wet & greasy surface especially when ambient sub 5 degrees C. I don't think these tires are winter rated at all, more summer tire. I have always ran BF Goodrich At's, the BFG's are definitely better in the wet. But they are £40-£50 extra per tire. The Coopers look awesome, and I'll run these until worn or I sell the truck. I will be going back to BF's on my next tire purchase.

Had these fitted new to my old Discovery 300Tdi as an upgrade, and they were a great choice.

As quiet as a road bias tire despite the chunky looks, were surprisingly grippy on tarmac in the wet or dry, (never aqua planed for example and were always grippy and progressive) and obviously didn't have any issues in grassy fields. I never had the opportunity to take them offroad seriously, but I suspect they'd be a safe choice given the tread pattern. I had them on for about 3000 miles before I sold the truck, and the tires had barely started to wear at that point. I had no issues with punctures or tears and in fact I'm looking for the same again for my current Discovery V8.
