1
) Tyre size and characteristics
Example:
245/35 ZR 20 (105Y)
245
= Nominal width (distance in mm from side to side)
35
= Height/width ratio as a percentage
ZR
= Radial tyre that can withstand speeds above 240 km/h.
Combined with the specific load and speed code (in brackets), this
indicates a tyre that can withstand speeds above 300 km/h.
20
= Rim diameter in inches
105
= Load index: numerical code associated with the maximum
load permissible on the tyre at a given pressure, at the speed
corresponding to the relative index. The maximum load permissible
is indicated in kg and pounds in the wording (3).
Y
= Speed index
This indicates the maximum speed at which the tyre can withstand
the load indicated in the load index.
Speed indexes (ECE-UN 30) are shown in the table below:
