Tyre size:
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.

A good tyre. More than capable on and off road. Although tread isn't aggressive enough fir real muddy conditions. But would buy and fit again.

Tyres seem good so far with no sign of ware. Slight road noise over my last tyres but nothing serious. A good compromise between off and on road. Very competitive price.

the tyre has been above expectation on the road, grip levels fine, of road when wet and muddy it has struggle compared to a full knobbly but on gravel trails it has been good.
