Tyres - dimensions

Updated 7/23/2018

The car's tyres have a certain dimension, see the examples in the table below.

The dimensions are stated on all car tyres. Example of designation: 225/50R17 98W.

225

Tyre width (mm)

50

Ratio between tyre wall height and tyre width (%)

R

Radial ply

17

Rim diameter in inches (")

98

Codes for the maximum permitted tyre load, tyre load index (LI)

W

Speed rating for maximum permitted speed, speed rating (SS). (In this case 270 km/h(168 mph).)

The car has an approval for the complete vehicle with certain combinations of wheel rims and tyres.

Warning

19-inch wheels must never be used on cars that are not equipped with the R-Design or Sport chassis options. The use of 19-inch wheels on cars with standard chassis constitutes a safety risk, with a risk of vehicle damage, and it impairs the car's driving characteristics.
