Re: e30 wheel/tire question

[Kurt Zimmerman <KurtZimmerman@xxxxxxxxx>]

That depends on several factors.  What is the width of the rim? what is 
the offset of the rim?

After researching this in depth for 15x7.5 in wheels, the conclusion is 
that the perfect offset is between 25 and 27mm.  If your wheel is 
narrower you can use a wider range of offsets.  16x7.5" wheels with 
205/50-16 tires will work with 22mm to 29mm offset. However, later  if 
you want to go with a 225/45 tire you'll need the wheels to be in the 
25-27mm range so that you don't have rubbing.

Given the lack of wheels with this size, you may have to use spacers...
