Is the offset diferent between the riveted ones (original series) and the welded (defender) ones?
Probably as there is a difference in series offset.
Think I've confused myself a bit so to recap
5.5 I think refers to the offset
This has opened one hell of a can of worms with no real sensible or definitive answer.
What I've found is
The standard wheel rims for the 88in Series Land Rover are not the same as for 109in wheel base version, the distance between the inside of the rim flanges (i.e. what the outer edges of the tyre beads will push against) is 5.0 inches on the SWB rim and 5.5 inches on the LWB rim.
SWB, Lightweight etc..5" wide, 5" offset
LWB, 90/110....5.5" wide, 4.75" offset
2A FC, Wolf, 1Tonne....6.5" wide, 4.5" offset
2B FC....6.5" wide, 4" offset
TD5 standard rim I think is 6" wide with 5.5inches offset
now I'm confused.com :doh:
