I smell a fish. A red herring, to be precise.

They can take a 16" or a 17" wheel with no problems. They won't even really mess up the steering geometry.

Over 18" and they could scrub the wheel wells, but the only problem really is inaccurate speedometers with oversize wheels on the car.

Nothing to worry about if you keep it within reason.

I have some write-ups in there, from when I owned my 740 Turbo.

I'll have to look at the wheels
Didn't notice they were bigger
So if its the case
mileage would actually be higher?
as one revolution was actually travelling a greater distance than a 15 in wheel?
say 1 or 2 inches extrra per mile

How many inches to a mile?...63360 inches to a mile so in actuality it was 63362 in per mile
63362 X 200000 =12672400000 in + 12 + 10560333000 feet + 5280=
200,006


so on 200 K its 3 extra miles per inch

Well, not much....
all approx of course

Really...
Can a larger tire adversely affect the long term life of the car?

Thanks

It is the outside diameter of the tire that matters. If the od of the tire is the same as original all the speedo and odo will read correctly. This is probably your situation.

No affect on logivity or anything else.
