.....Quick Question....Please Help

[BMW4LIFE]

i have a 1993 BMW e34 525i that i had 205 65 r15 and was wondering if the wheels would fit a 1988 BMW 735i with the tire size 215 65 r15...

my other question is that what are the measurements on the 15X7 right?

these are what the wheels look like...http://i7.photobucket.com/albums/y291/persian805/b7a2b807.jpg

Depends on the ET (offset) needed on the 7 series.

It would physically fit due to the 5 stud fitment, whether it would be bolted on correctly with the right amount of positioning (too near the body, too near the outside) depends on the offset. ET-20 or thereabouts is good for an E34, not sure on the 7-series (but older 7- series was same as E34).

However, the fact that its a 'bigger' combination you would be altering the final drive ratio slightly, which affects the acceleration, top-end and fuel consumption. I'll leave you to work out which way round :-) hint: better acceleration=lower top end and lower fuel consumption and vice-versa - its always a trade off. The calculation is to compare the 2 overall diameters complete with wheels and tyres [15 inches - in mm plus 2X215 or 205 X65%].

Cheers.

Would be a 2% differnace in tire size. 60 on speedo will actually be 58.8

Looks like they will fit
