Most speedometers are optomistic, but 4% is a bit much. I would also question the tire diameter, along with the tread amount.
Not all tires are equal in diameter, nor in actual sidewall width. You didn't specify brand or size in your post, but with your car you could have the folowing sizes:
6.5" x 15" - "Lysithea" 9-Spoke Alloy Wheels w/ 195/65/HR15 Tires
6.5" x 16" - "Mimas" 7-Spoke Alloy Wheels w/ 205/55/HR16 Tires
6.5" x 16" - "Orbit" 7-Spoke Alloy Wheels w/ 205/55/HR16 Tires
7" x 16" - "Metis" Alloy Wheels w/ 215/55/HR16 Tires
7.5" x 17" - "Amalthea" 14-Spoke Alloy Wheels w/ 235/45/HR17 Tires
7.5" x 17" - "Thor" 7-Spoke Alloy Wheels w/ 235/45/HR17 Tires
The info on the gas filler door should not be construed as gospel, but just a guidline.
