Tire Description

The HTR Z II (High Technology Radials-2nd generation) is Sumitomo's Ultra High Performance Summer tire developed for the drivers of sports cars, sporty coupes and performance sedans. The HTR Z II is designed to blend a unique appearance, dry and wet performance and ride comfort. Like all summer tires, the HTR Z II is not intended to be driven in near-freezing temperatures, through snow or on ice. The HTR Z II molds a high performance tread compound featuring ultra micro carbon technology and silica-based rubber into a directional pattern that features wide, arched tread blocks to enhance dry road traction and handling. A circumferential center rain groove and multi-direction water channels resist hydroplaning and enhance wet traction. The tire's internal structure features two steel belts with spirally wrapped Jointless Nylon Band reinforcement to enhance high-speed durability 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 accidental curb damage. NOTE: Sumitomo reassessed the HTR Z II line’s UTQG ratings in 2009. This resulted in tires featuring the same design, materials and manufacturing methods previously rated 220 AA A to be assigned UTQG ratings of 360 A A. Sumitomo has confirmed that regardless of the branded UTQG ratings, all HTR Z II tires are fully compatible and may be mixed individually or in pairs as necessary.

Customer Reviews

I've replaced all 4 tires on my 2002 Corvette and have roughly 1000 miles on these new Sumitomo HTR Z II tires, and I absolutely love them. I had never heard of them before and found them on TireRack.com looking for a better price on the factory GY EMT tires. I'm so glad I looked on Tire Rack and found the Sumitomo brand while shopping around for tire prices. These tires for the money are the best kept secret out there. They perform real well on the road when cornering and at higher speeds. There also a much smoother and quieter ride then an EMT tire. Which makes sense being they're a different type of tire, but after riding around on the EMT tires for 27,000 miles it is much more enjoyable to ride down the road in comfort and not have to have the radio blasting or having to speak loudly to the passenger to hear because of the road noise from the EMT tires. I've only driven the car in light rain so I cannot give a full report on the performance of the tires in wet conditions, but the tires seem to perform well. All I can say is if your looking for a quality tire at a low cost I highly recomnmend the Sumitomo HTR Z II. I would, and will, definately purchase these tires again in the future.
