I base wheel size on tire selection:

I wanted 225/45/17's This is a typical BMW size, however this was too small for my OE diameter of 195/65/15, but this would be an excellent 5th gen size.

Now some VW's, Bimmers, and Lexi (Europe) use 225/40/18, comparison to 195/65/15 yeilded a good match. So I went w/ 18'

I wanted to be sure I had an OE sidewall spec, tires are cheaper this way and you know the sidewall can take a trip down the road with a secure feeling that somewhere a car of similiar weight to yours is using this type of tire stock.

 

I am running H&R Sport springs with Tokico Blues.

When that pic was taken (2 years ago) I hadn't had my camber kit put in yet, but I have one in now and its pretty straight....I still need to get one of the rear wheels rechecked because it is off just a hair.

 

i have 17's but just switched back to my 15's for the winter....i can't believe the difference in pick up....i think i might get lightweight 16's for the summer now...
then again prolly not....
