Volkswagen Golf Service & Repair Manual: Identification markings on the tyre sidewall, tyres with run-flat system (PAX)

As compared to standard tyres, run-flat tyres (PAX) have different codes and designations on the sidewall. This makes it easy to identify run-flat tyres.
   
Codes and designations on tyres with run-flat properties (PAX)
245 -  Tyre width in millimetres
690 -  Tyre diameter (outer) in millimetres
R -  Radial construction
500 -  Nominal diameter of standardised rim seat
A -  Construction type index for the wheels with run-flat capability (PAX); “A” stands for asymmetric, since the two rim seats have different diameters.
99 -  Maximum permissible load of tyre (99 = 1550 kg)
Y -  Speed code (“Y” stands for a permissible top speed of 300 km/h).

Load rating code / load index (LI)
The load rating can be found on the sidewall of the tyre. It provides information about the maximum load that the tyre can bear.
The load rating is included in the size designation of the tyre (e.g. 195/65 R 15 91T). It is indicated on the tyre as a code according to ETRTO. The following table shows the load rating codes with the corresponding load capacity of the tyres.
