Sumitomo HTR-Z or HTR-ZII
What's the difference? Have any of you used both?

I run the II's... but mine are from before the tread pattern change.
info from tirerack site...
HTR-Z
A confident performer on wet and dry surfaces, the Sumitomo HTRZ takes the stresses and the loads of race track speeds in stride. Like all summer tires, the HTR Z is not intended to be driven in near-freezing temperatures, through snow or on ice. The offset "V" directional tread pattern efficiently removes water from the contact patch and prevents hydroplaning. The solid center rib helps maintain the car's directional stability, even on rain grooved highways. With it's high performance and low price, the HTRZ is one of the best values in an ultra high performance tire.
HTR-Z II
The Sumitomo HTRZ II is an Ultra High Performance Summer radial designed to blend appearance, performance and comfort. This combination makes the HTRZ II 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 II is not intended to be driven in near-freezing temperatures, through snow or on ice.
On the outside the HTRZ II'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 II 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.

Have you given the Sumi's a thorough testing yet? Curious as to your impressions of them....

I wish they offered the sizes I want. I want a little taller tire and Nitto has better sizes specifically their 295/45R18 and 255/45R18... but twice the price at 188 & 218.

Even the Sumi tires in 18 aren't bad, but I want a taller tire than they offer.
