The A.drive was a conventional tyre designed for good fuel economy, high mileage and good braking. It was the best selling Yokohama tyre in Australia. The Yokohama A.drive "conventional tyre" has been replaced by the Yokohama BluEarth AE01 which is an "eco tyre". Like the A.drive car tyre the BluEarth is designed for economical everyday driving. However, it uses Yokohama's patented orange oil technology and a light weight construction to improve fuel economy by up to 10% over the A.drive.
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.
See the chart below for a full list of speed symbols and their applicable values.
