What we need is a comprehensive guide to fitment of wheels & tires to 7 series models, specifically E32s. Please contribute your input to the size that you have personal experience with, noting the following details in a similar format so that others can be assured of success. If this works as a good summary, it can be done for other models as well.

Year and model (i.e. E32 1990 750iL)

Front Wheel diameter x width (i.e. 18x8.5), offset (i.e. Et15, 15mm, etc), tire width and aspect ratio (i.e. 235/45).
Results (i.e. slight rubbing of strut tower, no problem, etc)

Rear Wheel diameter x width (i.e. 18x9.5), offset (i.e. Et 15, 15mm, etc), tire width and aspect ratio (i.e. 265/35).
Results (i.e. rubs inside of outer fender, will not work, etc)

From this, a matrix can be developed to benefit all. Thanks.
