std wheel offset
Posted: Mon Apr 24, 2006 10:09 pmOK, I know this is a REALLY old post, but for the benefit of anyone who reads this in the future and wants to know, here's the answer:
The 13 x 5" 'styled' steel wheel (as fitted to GLs and the like) has a 4" backspace (i.e. 102mm), making the offset about 25p. The offset isn't stamped on the wheel, so this value is a very close approximate.
The 13 x 5.5" alloy 'Volante' wheel, which was optional on all Escorts but in my experience mostly seen on RS2000s, has a 4.25" backspace, making the offset also about 25p (same disclaimer as above).
