Sumitomo Passenger Tyre Range
| Feature | Benefit | |
| Asymmetric 5-rib pattern | 1 | Achieves high speed stability thanks to the asymmetric pattern with stiffer outer blocks designed to withstand increased centrifugal forces and inner blocks to provide excellent straight handling stability. |
| Lateral grooves | 2 | Long lateral grooves contribute to clearing water from the centre rib to the outer blocks during cornering. |
| Irregular wear control rib | 3 | The irregular wear control rib works to reduce irregular wear on the inner shoulder blocks. |
| Wide and straight grooves | 4 | Four efficient wide and straight grooves located in the tread area enhance wet performance. |
| In tire-bar sipes | 5 | Control shoulder block stiffness to reduce irregular wear and keep draining water as the wear progresses to ensure consistent wet weather handling. |
| 3D Wave-wall | 6 | Ensures water drainage and minimises centre rib movement for excellent handling response. |
HTR ZIII
The HTR ZIII is well suited to high performance, luxury sports cars and sedans. The asymmetric, 5-rib pattern with stiffer outer blocks provides excellent high-speed stability and control, while the advanced silica tread compound and groove design enhance wet weather performance and help reduce irregular wear.
