WHEELS AND TYRES
CARACTERISTICSRIMS
The wheels identification marking is represented in two ways:
- engraved marking for steel rims
- cast marking for aluminum rims
The marking enables acknowledgment of the main wheels dimensions criteria. This marking
may be:
complete,
Example: 5
1/2 B 13 4 CH 46 ; 5 1/2 J 13 4 H2 46
or simplified,
Example: 5
1/2 B 13 ; 5 1/2 J 13 H2
The wheel bolts (studs) are situated on a diameter of 100 mm.
Maximum axial runout : 1 mm measured on the rim edge ( in G ).
Maximum radial runout : 1 mm measured on the supporting side of the tires beads.
