Yes, if you get bigger tires it will say you are going slower than you are, and visa versa, you can go to a mechanic to get it recalibrated
Yes.
yes it changes the speedometer reading
A change in overall tire height will change speedometer accuracy.
Different heights of tire will change the speedometer reading.
It does not change the actual speed of a vehicle but changing tire size can affect the accuracy of the speedometer.
if the diameter will be greater or less then the speedometer will be effected
If the outside diameter changes, then the speedometer will change
yes!! of course, because the shaft is designed to rotate a certain speed, according to the car advancing speed.
It wont. They will only change when you increase/decrease the size dramatically as the wheel or tire. A one inch change wont make a difference.A more accurate answerIt's true that the size of the rim does not directly have any impact on the speedometer accuracy. But changing the rim size generally means that you'll be changing the size of the tire. The speedometer is directly affected by the circumference of the tire that is used. If you use a tire with a 10% larger circumference, the speedometer will indicate that you're going 10% slower than you really are. If you match the circumference of the 14 inch tire to the circumference of the 15 inch tire, the speedometer accuracy will not change.
The over-all size of the tire and wheel would change the calibration of the speedometer/odometer.
At 60 mph the speedometer will read 58.1 mph.
The answer depends on the size of the tire in relation to the original tire size. A tire with a smaller circumference will turn more at a given speed, which will cause a higher speed being displayed on the speedometer. A tire with a larger circumference will lead to a slower speed being displayed. The speedometer can be calibrated to correctly display the speed for a different tire size. Changing the size of tires on a vehicle will also change the way the vehicle handles and may cause faster wear on suspension components.
