The surface pattern of summer tires is relatively shallow, and the water-guiding grooves are relatively deep, because summer is a season with abundant rain. Such a pattern design shortens the braking distance on dry and wet land. For summer tires, the tire formula makes the tread moderately soft and hard, and the rolling resistance is low during normal driving, saving fuel.

But when the temperature drops below 7 degree , the tread rubber of summer tires will gradually harden. The tire grip and handling performance will also change accordingly. When summer tires are driven in winter, the tire safety performance decreases.

Winter tires are specially designed for weather environments with temperatures below 7 degree . Generally, winter tires use special rubber formulas and unique pattern designs to make tires safer to drive in winter. Not only does it improve the braking performance of tires and shorten the braking distance, but the winter tire pattern design is reasonable to eliminate snow and reduce slipping. Moreover, using winter tires below 7 degree also saves fuel and energy.
