Sumitomo HTR Z III Tire Review & Rating

The HTR Z III from Sumitomo is the company’s 3rd generation model of their best-selling high performance summer driving tire. Designed for drivers of sport coupes and sedans, the HTR Z III is made to deliver exceptional traction and handling on dry or wet roads, along with outstanding grip in the corners for more spirited drivers.

A silica enhanced high performance tread compound combines with a 5-rib asymmetric tread pattern and larger shoulder blocks for increased dry and wet traction. The tire’s continuous center rib and intermediate tread blocks provide added steering response and stability throughout the speed range, while also adding more cornering grip. You’ll also find a hard rubber filler in the sidewall that reduces flexing and adds to lateral grip without sacrificing ride quality.

HTR Z III Tires from Sumitomo

Wet traction is enhanced through circumferential and lateral grooves that effectively channel away water from the tread and increase resistance to hydroplaning. One area that Sumitomo put a lot of effort into is ride comfort. This is one of the more comfortable riding tires in this class due to the unique tread design they came up with. It dramatically reduces outside road noise that is quite noticeable.

Inside the tire you will find two wide steel belts that are polyamide wrapped for added strength and stability at higher speeds. A polyester cord body enhances ride comfort. Sumitomo offers sizes from 17-22 inches, and the tire comes with a Y-speed rating.

  • Outstanding performance and value for the money


  • Would like to see a little more treadlife

Overall Thoughts

The HTR Z III is arguably the best model in this line of HTR Z tires. The traction on wet or dry pavement is very good. Braking and acceleration are dependable, and the cornering performance of this tire is among the best in this class. The tire grips the road like glue. You really have to try to break the rear end loose with this tire.

Ride comfort is excellent with this model. Road noise is surprisingly minimal and not really a factor at higher speeds on the highway. Treadlife is average and could be better. Like most high performance summer tires, your driving style is pretty much going to be the determining factor in how long the tread lasts. That said, this tire provides exceptional performance and value for the lower cost. It makes for a good option in this category.
