Grip, braking, comfort... The choice of a motorcycle tyre impacts many aspects of your machine's behaviour, both on the road and on the track or off-road. It is therefore essential to carefully select the model that best suits your needs.
To help you gain clarity, 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

Other less significant references are also found on the sidewall of motorcycle tyres (country of manufacture, DOT marking, etc.)
Don't forget to regularly check your tyre pressure, as it is key to longevity and superior performance!
