The answer to this question largely lies in the region of the tire consumer. In moderate climates, summer tires do have advantages over all-season tires. Although they would not do well in winter conditions, summer tires tend to perform better in the heat and rain than all-season tires do. Thanks to their general design, summer tires maximize their contact with the road and create stability in these weather conditions.
Summer tires are known for their asymmetrical tread and shallow, straight grooves that work well in promoting braking and acceleration stability. Not to mention, the sticky tread of summer tires works well in the prevention of hydroplaning and resulting accidents. In general, summer tires even work well in periods of heavy rain.
However, it should be noted that summer tires work best in temperatures of 44 degrees or higher. They have a shorter tread lifespan and must be replaced more frequently than all-season tires. Yet, this is a minor price to pay for a tire that performs better than others. Referred to as "performance tires," summer tires are a popular choice among sports cars and luxury SUVs.
