Right I'm starting to look out for some rims for the car, i fancy some 16" for the road.
I used to run 205 40 16s on a 7.5x16 but can not remember offset.
Question is does the offset stay the same the larger and wider the rims get? I know et35 is about right, does that apply to a 15" and 16" rim and what happens if you go from a 7x16 to a 7.5 by 16 does the et still stay the same with the wider rim.
I would imagine there would be a different et for a wider rim on the same size alloys, if you get my drift.
I really fancy some borbet a's which unfortunately come in a et20
Cam someone explain the maths behind it and advise me
