It wont. They will only change when you increase/decrease the size dramatically as the wheel or tire. A one inch change wont make a difference.
A more accurate answerIt's true that the size of the rim does not directly have any impact on the speedometer accuracy. But changing the rim size generally means that you'll be changing the size of the tire.The speedometer is directly affected by the circumference of the tire that is used. If you use a tire with a 10% larger circumference, the speedometer will indicate that you're going 10% slower than you really are. If you match the circumference of the 14 inch tire to the circumference of the 15 inch tire, the speedometer accuracy will not change.
If the outside diameter changes, then the speedometer will change
A change in overall tire height will change speedometer accuracy.
yes it changes the speedometer reading
The basic rim size must always be 16 inch, however within limits you can change the width or aspect ratio.
the 16 inch steel rim is about 9.4kg
The over-all size of the tire and wheel would change the calibration of the speedometer/odometer.
Mercedes bolt patterns are universal. If you change rim sizes, be advised that your speedometer will not be accurate.

No!. It is very unsafe to mix tire and rim sizes.
Probably not. The rim may not clear the brakes.
Yes and so will a tire and/or rim change. To correct the problem you will need to reprogram the ECU to compensate for the new rear-end.
no you need a 16" rim
