Hi,

I've added the Audi rims, in 15x6" size.  They are 45mm offset, vs the 35?
for stock vanagon.  The rims are 6" vs 5.5", a difference of 12.5mm wider.
So if I look at where the tread centre line on the stock rims was compared
to the 15" Audi's I get (45-35)-12.5/2 = 3.75mm. A hair over 1/8" shift,
more technically known as dick all.

Keeping the SAME offset while going to WIDE tires is a problem, tire
centreline moves way out, bearing forces do go up, tracking/stability and
steering effort may all change.

I'm keeping my wheels on, the choice of tire types/brands in 15" is worth
the 1/8" ;)

bye, Tim

PS:  I'd be most concerned about rough machining of the rim centres, clean
that up with a file and emery cloth to get it radiused and smooth.  Sharp
corners start fatigue cracks more easily.
