- B - Illustration of standard tire
The reinforced side walls, unlike a standard tire, prevent tire flanks from pinching between the road and rim when flat.
Differences in Wheels in H2 and EH2 Version
-
The increased hump on the EH2 prevents the SST tire from springing off when pressure is lost.
-
EH2 builds up toward the center of the wheel.
-
The clearance to the brake is reduced.
SST Tires (RSC = Runflat System Component)
-
SST tires are identified with a special code (RSC = Runflat System Component) on the side wall.
Tires with Emergency Running Characteristics, Repairing
General Information
-
The wheel must be inspected before mounting, as with conventional wheel/tire systems.
-
The wheels should be checked for damage after a flat tire (true running, axial run-out, other damage) because the wheel could be damaged in an
emergency by driving through a pothole.
-
A damaged wheel should be replaced.
NOTE:
-
Flat tire sprays may be used on tires with emergency running characteristics (SST).
-
Tires must be replaced after running flat.
-
Observe manufacturers mounting instructions.
