What tyre size do you require?
The exact size of a tyre can be found on its sidewall.
The following chart shows you how to read a tyre size.
1. Overall tire width in mm
2. Ratio of tire height to tire width in%
3. Tire design: ''R'' = radial tires (widely used), ''D'' or ''-'' = diagonal tires (rare)
4. Required rim diameter for this tire in inches
5. Key figure for tire load capacity
6. Key figure for the permissible maximum speed (speed index)
7. Motorcycle tire identification, tires only approved for motorcycles
8. DOT labeling
9. Date of manufacture of the tire (week of production / year of production)

SPEED INDEX:
The speed index indicates the maximum speed intended for the tyre. Up to this value, the manufacturer guarantees optimum operation with the appropriate tyre pressure. The maximum speed allowed for this vehicle is given in the vehicle owner's manual; this information can be used to select the appropriate speed index for the tyre. The speed index is the last mark on the sidewall of the tyre.

good allround tyre
02.11.2009fromGray Barnes
Good all round tyre. Resists squaring off too quickly and hard wearing. I usually get around 12,000 km out of a set with mixed speed riding on a heavy cruiser.
14.05.2009fromA Williams (the daily grind)
Ride on Dunlop 404's front and rear - up to 6000 km's per month. Wouldn't want to risk a change to any other.
