A car tyre for everyday motorists who want save money on fuel. The BluEarth is an Eco tyre which uses low rolling resistance tyre technology to take drivers up to 8% further on a tank of fuel for highway driving and up to 10% further on a tank for urban driving. The orange oil technology in Yokohama's high tech Nano Blend rubber compound adds grip at a micro level. As a result, Yokohama's fuel efficient eco tyres have the grip Yokohama is famous for.
The load rating (represented by the numerical value) is related to the maximum weight that tyre can carry. So in this case 105 would refer to a load capacity of 925kg, with most passenger vehicle load indexes range from 62 to 126.
In all instances the tyres load index must meet or exceed the value displayed on the vehicles placard.
The speed category symbol, for example 'S', indicates the maximum speed at which the tyre can carry a load corresponding to its load index. So in this case, 'S' would refer to a maximum speed of 180km/hour.
