“Ultra High Performance Summer tyres are for driving enthusiasts who want a combination of a performance appearance, crisp handling and Z speed rated (or higher) durability along with dry and wet traction. Often used as Original Equipment (O.E.) on sports cars, performance coupes and high performance sedans, Ultra High Performance Summer tyres are not intended to be driven in near-freezing temperatures, through snow or on ice. O.E. Ultra High Performance Summer tyres are typically purchased as direct replacements for worn-out pairs or sets of the vehicle’s original tyres. They can also be used for other vehicle applications in complete sets of four or axle pairs if available in an appropriate size, load range and speed rating to match the existing O.E. tyres performance category and specifications.”
