Apart from size, type of vehicle and brand, weather is one of the most important factors to consider before buying tires for your car. Car tires are available in winter, summer and all-season. Winter ones are favorable during cold and rainy seasons when roads are relatively wet and, therefore, more slippery. They are designed to grant your car the required grip on the road and thus prevent you from accidents. Summer tires are preferred in the dry season when roads are dry. All-season are suitable in all-weather, whether summer or winter. Although suitable for all-weather, they have their pros and cons.
All-season tires are supposed to be convenient in all season, whether in summer, winter or snow. For example, you do not have to change your tires during winter or in snow conditions as for the case of other types of tires. They tires are relatively cost-efficient in that you do not have to purchase new tires depending on the weather, and a single set is convenient until they wear out.
As compared to summer tires, all-seasonare more durable and more resistant. They are believed to have the best quality/price ratio and are the most affordable high-quality type of tires. All-season tires have part of their tread patterns resemble summer tires; this design allows the tires perform well during warm and summer conditions. An example that stand out includes the Hankook and Vredestein Quatrac 3 brands. They also are silent as you drive and thus do not bother your comfort as you ride.
All-season tires are relatively more expensive than winter and summer tires. Purchasing a set tends to cost more than purchasing either a set of winter or summer tires. They have a relatively more aggressive pattern of treads that ensure high performance and grip in winter conditions, a design that would not be so efficient in summer conditions. Also, this aggressive tread design is not cost-efficient in the summer in that more fuel is unnecessarily consumed.
They tend to have a relatively longer braking distance as compared to the specific brands due to their slower response, a characteristic that can be risky in some situations such as during emergencies. Some of them are vulnerable to hydroplaning. They are not suitable for very low temperatures, usually below 7 °C or when there is more than just some traces of snow on the ground. This is because, under such conditions, these tires easily lose grip risking the driver and those onboard of accidents (read here specificity and how to choose winter tyres).
It is usually advisable to ensure maximum safety through having different sets of tires for whatever weather. Tires provide the surface area connecting your car to the ground, and, therefore, selecting the most suitable set is very vital for your safety. It is recommended that routine maintenance such as repair, checking for punctures, and maintaining the correct amount of pressure is key for your safety and the lifespan of your car. It is also advisable to have a common set for all four. This is to ensure uniformity in braking, grip, and the expected lifespan.
