The primary benefit of all-season tires is that they balance the ability to overcome weather-related driving hazards throughout the year, reducing the need for drivers to change tires for different seasons, according to Popular Mechanics. All-season tires allow for modest gripping in the snow and decent summer gripping.
All-season tires normally have some lateral stiffness but an increased number of biting edges, according to Edmunds. Their performance isn't typically as strong as snow tires in the winter or summer tires in the summer, but they save the time and money involved in changing out specialty tires. All-season tires are also the default on many new cars as of 2015, which means consumers normally have many options from which to choose based on quality and pricing.
Though quality varies by tire model, there are all-season models that allow for excellent water dispersing in the summer just as summer tires do, according to Popular Mechanics. This feature is important for driving safety during rainy seasons because it allows the tire to stay in better contact with the road. Though some tires aren't good enough quality, there are all-season tires with grips that are adequate during the snowy summer months. An all-season tire's winter grip is better than a summer tire's grip in the winter and without the hassle of swapping tires.
