Tyres - dimensions
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: 215/55R16 97W.
|215||Tyre width (mm)|
|55||Ratio between tyre wall height and tyre width (%)|
|16||Rim diameter in inches (")|
|97||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).)|
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.
The car has an approval for the complete vehicle with certain combinations of wheel rims and tyres.
