Yes, it will throw off your speedometer and your odometer. This is how to know how much. Measure from center of hub to the floor of a mounted wheel and tire properly inflated. Say for example you measure 14.4 inches with your 19 in. Wheels. Now if you mount 16 in. wheels and measure as before and you might get 13.25 inches ( I do not know what that measure will be). My 19 inchers are 14.4. Now divide your 16 in. Measure by the 19 in. Measure. 13.25/14.4 = .92. So your speed will be 92% of the speedometer reading.
