This tire targets enthusiast drivers who desire performance tire capabilities without premium brand pricing, delivering confident performance on both dry and wet roads for spirited driving.

Available in sizes ranging from 17 to 22 inches with Y-speed ratings (up to 186 mph), the tire demonstrates Sumitomo's commitment to providing performance-oriented products for the value-conscious enthusiast market.
The Sumitomo HTR Z III utilizes internal construction featuring two wide steel belts wrapped with polyamide reinforcement for added strength and high-speed stability, while a polyester cord body enhances ride comfort. Long lateral grooves evacuate water from the center of the contact patch, with four straight wide circumferential grooves further heightening drainage for improved wet performance and hydroplaning resistance. Independent testing and user reviews averaging 83% across 149,000 miles consistently praise the tire's excellent value proposition, with Consumer Reports awarding Excellent ratings for dry braking and hydroplaning resistance. Users report very good dry and wet traction, surprisingly quiet operation for a performance tire, and excellent ride comfort, though tread life is average for the category as driving style significantly influences longevity. The HTR Z III serves budget-conscious performance drivers seeking capabilities approaching premium alternatives at significantly reduced costs, making it a popular choice among grassroots motorsport participants and enthusiast daily drivers who prioritize value without sacrificing essential performance characteristics.
