Cooling Unit Installed at Yokohama’s Hokkaido Tyre Test Centre

The new unit helps to set up the temperature of the ice surface anywhere between –10°C and 0°C (14 and 32) at a room temperature of 5°C (41) for winter tyre testing

Yokohama Rubber installed a new cooling unit, which helps to set up the temperature of the ice surface anywhere between –10°C and 0°C (14℉ and 32℉) at a room temperature of 5°C (41℉), in the indoor ice-surface testing facility at its Tyre Test Centre of Hokkaido.

The installation of the cooling unit will support tyre testing of studless snow tyre at reliably precise temperatures throughout that range.

In addition, it has given Yokohama new capacity for testing on ice in early winter. That lengthens the seasonal span over which Yokohama can conduct brake-testing on ice and broadens Yokohama’s R&D calendar. The company can thus undertake a greatly expanded scope of ice-surface testing for studless snow tyres, studded tyres, and all-season tyres.

The Tyre Test Centre of Hokkaido was opened in December 2015 to expand Yokohama’s tire testing capacity in line with the global expansion of its tyre business, and to introduce more sophisticated evaluation methods. That globalization necessitated increasingly advanced testing of a growing number of winter tyre sizes. Yokohama tests winter tyres for passenger cars and for trucks and buses at the centre.

It also tests summer tyres at the centre during the months from spring to autumn. Yokohama opened the indoor facility for ice-surface testing in January 2018 to test winter tires at precisely controlled surface temperatures.
