Unless you have a broken speedometer, you are traveling at 55 mph.
Speed - but NOT velocity.
I have a 2004 Honda Civic. The Speedometer rests at 35 MPH and when traveling at 55 MPH, it reads 85MPH.
Yes. The speedometer reads off the transmission tail shaft, and the speedometer is geared (in a mechanical system) or programmed (in an electronic system) accordingly.
It reads instantaneous speed, and tells you nothing about average speed.
The speedometer on the Fiat punto Mk1 was made with a speedo that reads 5 mph min. There is a needle stopping the speedo from going below this, so you dont need to "fix" anything as this is standard.
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
75mph

It reads of the 2 transmission output shaft or the 4wd transfer case output shaft. Basically it reads how fast the output shaft is moving and sends that reading to the computer and the computer sends it to the speedometer. Without it the speedometer doesn't work.
Yes, you can There will be about a 5% decrease in the tire diameter. 225 65 tires are 225mm wide and 146.25mm in height (65% of the width), while 215 60 tires are 129mm tall, which will affect the odometer and speedometer. When your speedometer reads 60 mph, you'll actually be traveling closer to 57 mph. Replacing the 225 65 tires with 215 70 tires would keep the diameter almost the same (150.5mm).

Check VSS(vehicle speed sensor)on tranny,the most common problem of speedometer errs,providing your vehicle is equipped with a speedometer cable.Also,VSS,will cause erratic speedometer reads. - Big Daddy
