Grand Touring Summer tires are designed for drivers who value a combination of stylish aesthetics, adept handling, and high-speed endurance (H-rating or greater). These tires offer excellent traction on both dry and wet roads, making them well-suited for use on sophisticated coupes and luxurious performance sedans. However, it is important to note that Grand Touring Summer tires are not intended for driving in near-freezing temperatures, on snowy terrain, or icy surfaces. When it comes to replacement, O.E. Grand Touring Summer tires are commonly chosen to directly replace worn-out pairs or sets of the vehicle's original tires. If available in the appropriate size, load range, and speed rating that matches the vehicle's O.E. tires, they can also be used for other vehicle applications in sets of four or pairs for the axle. It is crucial to ensure that the chosen tires align with the specific performance category and specifications of the existing O.E. tires. In summary, Grand Touring Summer tires offer a sophisticated appearance, confident handling, and high-speed durability. They deliver excellent traction on dry and wet surfaces, but caution must be exercised when driving in near-freezing temperatures, snow, or ice. These tires are often chosen as direct replacements for worn-out O.E. tires and can be used for other vehicles if they meet the necessary size, load range, and speed rating requirements.
