To help you understand better, here are some explanations that will assist you in deciphering the information found on motorcycle tyres:

• Dimensions: width of the tyre in millimetres and height of the tyre as a percentage of that width. E.g. 190/55, for 190 mm wide and 55% high
• Structure: radial (ZR, or R) or diagonal (B), both tyres must be identical in this regard
• Diameter: expressed in inches, e.g. 17 or 19
• Load index: maximum load that the tyre can support
• Speed index: maximum speed that the tyre can support
• M/C indicator: purpose of the tyre, M/C for motorcycles
• With or without inner tube: TL ("tubeless") for tubeless tyre, TT ("tubetype") with inner tube
