depends on the tire circumference/diameter, not the rim size, same diameter, same speedo reading.

with 16 inch wheels, you should be running a 225/55/16 tire. That would be stock diameter

Here is a good tire size comparison calculator. All you need is the stock size, 225-60-15, and the new tire size to see what affect, if any, it has on your speedometer:
