Sumitomo HTR66 HTR Z5 255/40ZR19 100Y XL Ultra High Performance Summer Tire

The Sumitomo HTR Z5 is an ultra-high performance summer tire designed for drivers of sports cars, sporty coupes, and performance sedans seeking responsive high-speed handling and reliable traction in warm, dry, and wet conditions. This tire features an aggressive summer compound molded into an asymmetric, five-rib tread pattern that delivers exceptional grip and cornering stability at high speeds.

Key Performance Features:

• Continuous center rib aids stability and improves steering response, while substantial shoulders improve lateral grip
• Wide circumferential grooves and lateral shoulder grooves evacuate standing water from the footprint for hydroplaning resistance
• Increased shoulder and contact patch puts more rubber on the road to boost handling capabilities and reduce uneven wear
• Internal construction includes a nylon casing with two steel belts, spiral wound nylon cap layer, and hard apex that strengthens the shoulder and sidewall
• Tread pitch is randomized and computer tuned to help keep road noise to a minimum

The HTR Z5 delivers cornering, braking, and steering response performance that are almost at racetrack level, while maintaining comfortable and quiet highway manners with civilized behavior and good isolation of road bumps. This tire has earned a reputation in the tuner car community for providing excellent value and performance.

Important Note: Like all Ultra High Performance Summer tires, the HTR Z5 is not intended to be serviced, stored, or driven in near- and below-freezing temperatures, through snow or on ice. This tire should not be used if temperatures are below 45 degrees Fahrenheit.

The Sumitomo HTR Z5 is not covered by a manufacturer's tread life warranty, but Sumitomo does offer comprehensive coverage against defects.
