Rated 4 out of 5 by from Great snow tire I drive my Chevrolet Avalanche in the mountains once a week during ski season. I frequently encounter unplowed, snow packed, ice packed, wet, and slushy roads on my trips. I have driven in both dry and wet snow conditions. I used to run all terrain tires but these tires handle anything you push them through without skipping a beat. The road noise is slightly more than an all terrain tire but much better than a true mud tire. I run my tires all year round and only got 35000 miles out of my first pair. That said these are the best snow tires I have driven on other than studded tires.

Rated 1 out of 5 by from The entire website is useless with no prices! USELESS! And you want 50 more characters when you leave the most important description off all the tires, and that is the price!

Rated 5 out of 5 by from very good winter tires I have run Blizzak tires and Have these tires now. They are rotated with regular tires in non winter season. This reduces wear. They provide excellent traction. Please note all winter tires wear down quicker if run year round. The rubber used provides excellent wet and snow traction. However, it is a softer compound that wears out in hot weather or if on 4 wheel drive mode. They are the best winter tires I have owned. Would not hesitate to buy them again.

Rated 5 out of 5 by from Love these tires Bought these tires for plowing and all around winter traction, was very impressed with these tires, great traction in the deepest snow, great on even ice! Had no problems moving snow with these tires, have them on a 2000 Ford ranger and have moved them to every vehicle I've owned

Rated 5 out of 5 by from Discoverer M+S tires perform extremely well on snow and on ice I installed five (5) LT235/80R17 on a Jeep JKU Sahara. For winter operation, I wanted narrower tires than the stock 255/70R18. The Discoverer M+S tires perform extremely well on snow and on ice. The noise level is minimal to non-existent. Being load rating E, the LT235/80R17 are stiff and the air pressure have to be adjusted to a lower pressure in order to improve the ride quality.

Rated 3 out of 5 by from Good in snow but don't last. These tires are good in snow, that's why I bought them. I snow plow and I never got stuck. I have had them for about 2 years and less than average mileage on them. Last year I had to replace one for hitting a pothole. The cords could not it. Now I have to replace another one I believe for the same reason. So I wouldn't recommend these tires unless you drive on perfect roads or are able to swerve in traffic to be able to miss the potholes.

Rated 5 out of 5 by from Absolutely top notch On our 4th winter season on these tyres they still perform very well. Ours are not studded, and we don't miss the studs at all, even when "everyone" says studs are mandatory on SUVs where we live (Norway). Very precise in all maneuvers: Ice, hard snow, dry snow, wet snow, wet or dry tarmac. They gets very soft in temps above +10°C, so not meant for several plus degrees, can't complain on this as they are pretty much the perfect winter tyre. Quite high rolling resistance, so they reduce mpg by approx 10%. Now I cannot find them anymore at tyres stores, so I'm afraid I will have to buy something else next time :-( '06 Mitsubishi Pajero/Shogun/Montero LWB 3.2 DiD, 245/70-17.

Rated 1 out of 5 by from Worst snow tire ever! I have a 2015 Chevy 2500, and was told these tires were as good as Goodyear Ultra grip ice WRT. Not even in the same league. I should have waited till the Goodyear were available. As I live in winter most of the year, and have owned many different snow tires, I can attest these are the worst I have ever owned. With the Goodyear, I almost never had to put in 4WD, and with the Coopers, I can never take it out, on simple packed snow. Thanks Cooper!!
