Volkswagen Golf Service & Repair Manual: Run-flat tyres, structure and identification of a SST tyre
| Removing and fitting run-flat tyres
→ Chapter. |
| If run-flat tyres are used, a Tyre Pressure Monitor display
must be fitted. |
| Damage to the tyre and the resulting pressure loss cannot be
detected with the naked eye. |
|
|
|
| SST tyres are identified by a specific sign (RSC = Runflat
System Component) in the sidewall. |
| The identification for run-flat tyres on the sidewall may
differ depending on the manufacturer. |
| Self-supporting tyres are tyre systems with run-flat
capabilities in the case of pressure loss. In case of a deflated
tyre, the driver can still drive to the next workshop whereas
some restrictions must be adhered to
→ Owner's manual. |
| In case of a complete pressure loss, the SST tyres allow for
moderate driving with a maximum speed of 80 km/h and over a
maximum distance of 50 km. |
| The distance that can be travelled during a breakdown
depends on the driving style, the vehicle speed, the road
condition, the weather conditions, the condition of the tyres,
and the tyre load. |
| In case of a complete pressure loss, the wheel must not be
changed immediately, if SST tyres are fitted (e.g no wheel
change in poorly visible and hazardous road sections). |
| The brakes, the steering system and the drive train feel
similar, even after a complete pressure loss in the tyre. |
| If SST tyres are used, no spare wheel is required. This
allows for more space and a lower weight in favour of the
customer. |

When a standard tyre deflates, the side walls are pressed
together by the wheel rims. The rubber material heats up
extremely and comes off the tyre quickly when the tyre is
deflated. |
| SST tyres with reinforced sidewall |
| The SST technology is based on self-supporting reinforced
sidewalls. |

Extra thick sidewalls -A-
support the deflated tyre on a standard wheel rim, and the
vehicle remains operable. A special rubber compound reinforces
the tyre and is capable of carrying the vehicle in an emergency. |
| The reinforced sidewalls do not become pinched between the
road and the wheel rim if the tyre is deflated. |
| Differences between H2 wheel rims and EH2 wheel rims with
extended hump
|
| In case of a pressure loss, the extended hump of wheel rim
EH2 prevents the SST tyre from becoming detached from the wheel
rim. |
| The extended hump wheel rim EH2 is higher relative to the
centre of the wheel. |
WARNING
| There is a smaller clearance to the brake. |
