I have the Cooper Evolution Tour currently on my Equinox. They replaced the OEM Michelin Latitude that came on the vehicle. I have almost 16,000 miles on the tires now and they are overall better than the Michelin. Quieter, ride better. Steering response is virtually the same. Wet weather performance is OK. They will spin from a start on a wet/damp road, and can get squirrelly if you go too quickly in to a curve or turn on a wet road. Snow performance is adequate, I am sure the AWD on my Equinox helps somewhat with regards to that.
Treadlife has been OK. They started with 9/32" when new, and are down to about 6/32" on all 4 corners now after 16,000 miles.
I would definitely buy Cooper tires again, although I would probably go for a tire in the Discoverer line next time.
