I have just been out and taken measurements. The offset comes out at 43mm so should be good.
Just to clarify, the wheels are 7J so 7" wide.
7" % 2 = 3.5" to the centre line.
3.5" = 89mm
Distance from edge of back face of the rim to the hub mating face = 132mm
132mm - 89mm = Offset
Offset = 43mm
I have no signs of inner arch rub so hopefully with a set of 195/50/15 tyres I should be good to go.
Cheers,
Smiler.
