Cooper Discoverer True North: the best Cooper winter tire
The Cooper Discoverer True North is the dedicated winter tire recommendation for truck and SUV owners seeking maximum winter performance. The winter-grade silica compound remains flexible in sub-freezing temperatures where all-season rubber hardens and loses grip. The 3D full-depth sipes create thousands of biting edges against snow and ice, and the tread void pattern effectively expels snow to maintain continuous traction.

Cooper Discoverer True North: the best Cooper winter tire
The Cooper Discoverer True North is the dedicated winter tire recommendation for truck and SUV owners seeking maximum winter performance. The winter-grade silica compound remains flexible in sub-freezing temperatures where all-season rubber hardens and loses grip. The 3D full-depth sipes create thousands of biting edges against snow and ice, and the tread void pattern effectively expels snow to maintain continuous traction.
Cooper AT3 4S: best for mild-to-moderate winter regions
For drivers in regions with occasional rather than consistent winter weather, the Cooper AT3 4S three-peak certified all-terrain provides outstanding snow capability in a year-round design. The 3PMSF rating means it exceeds the threshold for severe snow traction that standard all-season tires do not meet. For a driver who encounters snow 10 to 20 days per year rather than 80 to 100, this is an excellent compromise between winter capability and the convenience of not changing tires seasonally.
How to choose
Dedicated winter versus all-season with 3PMSF
For regions with regular ice and packed snow, a dedicated winter tire outperforms even 3PMSF-rated all-seasons. For occasional snow regions, a 3PMSF all-terrain or all-weather tire provides adequate capability without seasonal swaps.
Compound flexibility
Winter tire rubber compounds are specifically formulated to remain elastic below 45 degrees F, providing grip when standard all-season compounds harden. This compound difference is the primary reason dedicated winter tires outperform all-seasons in cold temperatures even on dry roads.
Full-depth siping
Sipes bite into snow and ice. Full-depth sipes maintain traction as the tire wears, unlike partial-depth sipes that disappear mid-tread life and reduce winter capability as the tire ages.
Load and speed ratings
Verify that any tire you consider meets or exceeds your vehicle's required minimum load rating. Do not install tires with lower load ratings than specified by your vehicle manufacturer.
Second wheel set investment
If you commit to dedicated winter tires, a second set of steel wheels (typically 200 to 400 dollars for a set of four) makes seasonal swapping a one-time 30-minute driveway task rather than an annual trip to the tire shop. The total cost of owned wheels plus dedicated winter tires often pays back in improved safety within one or two prevented incidents.
Storage
Store off-season tires in a cool, dry, dark location away from ozone sources (electric motors, furnaces). Proper storage extends tire life and maintains the rubber compound's cold-weather performance properties.
Common questions
The Cooper Discoverer True North is the dedicated winter/snow tire for trucks and SUVs with the best snow and ice performance. The Cooper Weathermaster Ice 100 is the passenger car winter tire option. For all-terrain vehicles who want three-season capability including serious snow, the AT3 4S is Three-Peak Mountain Snowflake rated.
No. Three-Peak Mountain Snowflake (3PMSF) certification means the tire meets USTMA performance requirements for severe snow traction, which is significantly better than a standard all-season tire in snow. However, a dedicated winter tire with winter-compound rubber still outperforms a 3PMSF-rated all-season on ice and packed snow due to compound flexibility at low temperatures.
All-wheel drive helps with acceleration and getting moving in snow, but it does not improve braking or cornering performance on snow and ice. Four winter tires provide superior braking and handling in severe winter conditions compared to AWD with standard all-season tires.
Dedicated winter tires typically last 4 to 5 seasons when used seasonally and stored properly during warm months. Using them only in winter (swapping to all-seasons in spring) extends their life significantly compared to year-round use.
