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