Can I drive MS tires in summer?

Driving winter tires in the summer can wear them out faster. That’s because the rubber compound in winter tires is designed for colder conditions, not warmer temperatures.

And the special tread removes more water from the ice. The test results show that winter tires outperform allseason tires on ice, too.

Are mud and snow tires the same as winter tires?

Winter tires are specifically designed to provide traction in deeper snow and in sub-zero temperatures. Mud and snow tires will perform just fine in lighter snow but, if you regularly drive in snowy conditions at temperatures lower than 7°C, you’re better off with a set of good winter tires.

Can I drive to Big Bear without chains?

R2: Chains are required on all vehicles except four-wheel-drive vehicles under 6,500 pounds gross weight and equipped with snow tires on all four wheels. Chains for one set of drive wheels must be carried by four-wheel-drive vehicles using snow tires.
