Sumitomo HTR T4

All-season passenger tire of one of the most famous Japanese manufacturers Sumitomo HTR T4 is designed for passenger cars of various categories. The manufacturer refers to this tire as "premium".

The symmetrical non-directional tread pattern has the most relevant five-rib design of our time. It is also worth noting that the pattern was developed with the help of computer modeling technologies. Like most analogs, the tread pattern of this tire has one solid rib, located exactly in the middle of the tread, two central ribs and two shoulder zones.

Thanks to the solid design of the central rib, as well as its large width, the tire demonstrates instant response even to the slightest movement of the steering wheel, as well as excellent directional stability. Two adjacent ribs are divided into separate blocks by transverse grooves, on the surface of which there are longitudinal and transverse lamellas. This made it possible to provide the Sumitomo HTR-T4 tire with an excellent handling character when moving on various types of surfaces, including very wet roads.

Thanks to the transverse grooves, as well as their curved shape, the water drainage from the tire's contact patch has been significantly improved. However, the main means of combating aquaplaning are still the four longitudinal drainage grooves that are continuous along the entire length of the tread.

The shoulder zones of the tread have a layer of nylon fibers wound by a seamless technology, which significantly reduced the degree of tire deformation that occurs during lateral acceleration. In addition to improving the coupling characteristics when cornering, this led to an increase in resistance to uneven wear.

Main features of the Sumitomo HTR T4 tire

- The tread pattern created with the help of computer modeling tools provides excellent traction under various road and weather conditions;
- Low noise level, exceptional wear resistance due to the optimized tread pattern;
- A high content of silica in the rubber compound provided the tire with excellent traction on wet roads and high resistance to abrasion.
