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.

The tyres are grand. They are tires. I would however like to make a point of saying http://moto-tyres.co.uk/ gave me the worst service I’ve ever had in my life. The original tire I ordered wasn’t in stock and it took them about 2 months to deliver it to me. Customer service was a joke and I spend more time chasing them up on their false promises then I did actually using the tires. On if the most stressful experiences I’ve ever had to go through ordering online. Don’t use http://moto-tyres.co.uk/ to get your tires is the only valid feed back I can give.

These tyres are a soft compound and wear quickly if used on the road.
