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℃, 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℃. 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℃ also saves fuel and energy.
However, winter tires designed for low temperatures are not as good as summer tires in terms of handling, comfort, and other aspects when the weather warms up, so they should be replaced with regular tires.
At this time of year, frequently changing tires is a hassle for car owners, and it is also an expense for car owners. Therefore, many car owners simply do not change tires. However, the roads are slippery in winter, and the performance of tires is reduced, so many accidents occur in winter. For the safety of life and property, winter tires should be replaced in time.
