Sumitomo HTRZ – The Sumitomo HTRZ is an Ultra High Performance Summer radial designed to blend appearance, performance and comfort. This combination makes the HTRZ appropriate for many of today's sporty cars because it provides a unique look with a size lineup of 17" and 18" rim diameter "Plus Two" and "Plus Three" fitments. Like all summer tires, the HTRZ is not intended to be driven in near-freezing temperatures, through snow or on ice. On the outside the HTRZ’s tread pattern features extra wide, arched tread blocks to enhance dry road traction and handling. The blocks vary in size and shape to help minimize noise levels and are separated by Multi Direction Water Channels to help increase wet traction and resist hydroplaning. On the inside the HTRZ features two steel belts with spirally-wrapped Jointless Nylon Band reinforcement for high-speed durability and predictable handling while minimizing weight and improving ride uniformity. The lower sidewall features Single Strand Beads for improved wheel fit and Wheel Flange Guards to help protect alloy wheels from curb damage.
Mounting and Balancing - OE Wheel Distributors is committed to utilizing the latest innovations in the automotive industry and all balancing is performed on a Hunter Road Force Balancer GSP9700. This is the same process used in Indy and NASCAR circuits. The GSP9700 Vibration Control System extends far beyond the traditional functions of a wheel balancer. It not only solves wheel balance problems, but also “road tests” the tire/wheel assembly to eliminate virtually every variable causing vibration in relation to the tire and rim. The exclusive Road Force Measurement® System applies up to 1400 pounds (635 kg) against the tire, while rotating the wheel and tire at high speeds, thus imitating road force conditions. The loaded roller detects non-balance, radial force related vibrations caused by eccentricity and constructional variation of the tire and wheel. Unlike non-contact measurement, the roller samples the entire footprint of the tire including the sidewall’s contribution to ride quality. Road force balancing provides the best balancing available in the industry, and the Hunter GSP9700 is the most technologically advanced balancer in the Industry.
