2 Sumitomo HTR Z5 275/40R18 103Y Maximum Performance Summer UHP Tires Brand New HTR68 / 275/40/18 / 2754018

Sumitomo HTR Z5 is an ultra-high-performance summer tire designed for sports cars, coupes, and performance sedans. The tire’s continuous center rib adds stability and improves steering response, while the substantial shoulders improve lateral grip. Four wide circumferential grooves help to evacuate water from the tread area for advanced hydroplaning resistance. HTR Z5’s increased shoulder and contact patch ensures even distribution of pressure to prevent irregular wear and improve handling performance. The internal construction consists of full-width nylon band that optimizes high-speed stability, and high-rigidity steel belts that offer greater durability and car stability. Hard apex strengthens sidewall for exceptional cornering stiffness.
