Customer Reviews

Rated 5 out of 5 by from Overall Great Performance on and off road I use these exclusively in the winter, but occasionally the weather gets warm before I take them off. This is going to be my fourth winter using them. I only wish I had them studded. I still use chains for really deep snow or ice, especially on steep forest service roads. Compared to standard street tires these tires are far superior. They're not a dedicated ice tire, but they last far longer. I do most of my driving on dry pavement and these tires are holding up fine and are much quieter than my ATP all terrains.

Rated 5 out of 5 by from Best tire I have ever ran in the snow! I put these on my Dodge Dakota for the winter because the factory Goodyear tires are junk but still have plenty of tread left. They are by far the best car I ever rain in the snow! And for the guy who only got 32,000 miles out of them that is impressive for a snow tire!

Rated 5 out of 5 by from My go-to, get thru snow tire I have these tires on a 3/4 ton plow truck; when they wear out I will replace them with another set.

Rated 5 out of 5 by from Amazing Tire! Put these on and the next day I was driving in 18 inches of heavy wet snow without chains. I was able to go places that other trucks couldn't go with chains on. Night and day difference from my AT3's. These perform in all conditions very well. This is the 3rd season with them and the studs are still good. I bet they're good for 3 more seasons. AAA+

Rated 5 out of 5 by from NW Michigan Winter I am not sure why people are complaining about this tire. They are for sure a winter tire and like any winter tire they will not last. I use them from the time it first snows to about march/april when there is no more snow and the temperatures stay <45 deg. If it starts to get warm out they come off. I literally never put my 2016 4runner in 4WD once after using these vs the garbage stock tires they came with. I felt very safe using these for winter driving and a complete night and day difference using these vs. the stock all weather dunlops.

Rated 5 out of 5 by from Best winter tire ever I have close to a million miles on these tires, I put on 65K miles every year and I get my new M+S every November and at 65K there always some meat left, not a lot but some. I drive in snow on the average of 7 months, so I do use them as intended, as a SNOW TIRE and they work so well on snow and ice, it's hard to describe, as for rain and mud they still do a great job and never had a hydroplaning issue, I can always count on them and have. I rotate every 10K in cold weather and 7K when warm. I do know they are a snow tire and expect more wear when warm and in a million miles I think I have had 3 repairs. Hope they always make these tires!

Rated 5 out of 5 by from 2nd set purchased. I originally purchased the 1st set when they were made under the Dean tire brand known as the WinterCat SST. Excellent winter tires. Even tread wear with proper 5,000 mile rotation. Road noise does increase with wear but tolerable. Hoping since Cooper makes them now that I will find the same great characteristics as the original WinterCat SST in the Discoverer M+S. Highly recommended for winter use.
