Profile: Yokohama Geolandar H/T G056

The latest SUV offering from Yokohama has a 21% improvement in wear performance and a 30% improvement in handling over its predecessor

by Rachel Evans

 

In the development of Yokohama’s new M+S category Geolandar H/T G056 SUV tire, engineers benchmarked against all-season competitors rather than summer tires. The product, which is designed for the European market, is the result of extensive market research conducted by Yokohama. Results highlighted three important performance characteristics: wet braking, handling and wear.

In wear performance, Yokohama has achieved a 21% improvement over the predecessor product, and an improvement of 30% for handling performance.

These achievements are the result of a culmination of key technologies including a new compound containing high levels of silica, and a low Tg polymer which strengthens the binding force of the carbon and silica. The G056’s compound also features Yokohama’s orange oil technology.

Simulation was key to the optimization of tire noise for both the pattern and pass-by noise. Physical tests were predominantly carried out at Yokohama’s proving grounds in Japan and Thailand and, according to Yokohama experts, this included extensive evaluation on dry dirt and in snow because although the G056 is positioned as an M+S category tire it is not designed for driving on deep mud. Test vehicles included a Toyota Hilux and Land Cruiser, and a Mercedes G-Class.
