Calculations for several wheel/rim sizes - The BMW 8 Series (E31) Forum

Here are some pre-calculated tire sizes, factory for 8-series is 235x50-16 which are 25 1/4" tall.

I went with CSI sizes:

Front - 245x40-18 which are 25.72" tall, a 0.47" difference from stock
Rear - 285x35-18 which are 25.85" tall, a 0.60" difference from stock

Also, I have adjustable camber plates in the front and although the H&Rs lowered it by more than an inch, the plates raised it up around 1/4 inch. I also have Bilstein Sport Shocks.

Here are some pre-caclulated sizes and the formulas, plus some pictures.
