Sorry, but unless the aftermarket wheels and tires are the exact same diameter as the stock setup than your speedometer reading is always going to be off.
Here's a nice calculator to see how fast you're really going...

What are the biggest size wheels you can throw on a w208 w/out affecting the performance of the speedometer and/or odometer?

My car is 1/4" taller with the 18's than with the 17's, my original tires where 25" in diameter, the new ones are 25.4" That means that my car will be slower 0-60, but faster at high speed. I will change spring pads to compensate for the height.

Actually, it's only the wheel height that becomes a factor in speedometer reading and actual speed variations.
