How does tire size affect the speedometer in a car?
The speedometer in a car runs based off the speed of the transmission. The gears in the transmission spin at a known rate for the speed the vehicle is traveling at. The faster the gears spin the more the speedometer goes up. If a person replaces stock tires with larger tires, then the tires will spin slower, which will cause the speedometer to read at a value that is less than the actual speed.
Do motorcycles go faster than the speedometer?
Usually, stock vehicle speedos will show a little more than actual speed. But if the vehicle has been modified, all bets are off.

How do you know that a speedometer tells you the instantaneous speed of a car?
Because when you look at the speedometer it is telling you your speed at that particular instant in time, it changes from instant to instant.
Why cant a car not go faster than the speed on the speedometer?
A car cannot go faster than the speed shown on the speedometer because the speedometer is connected to sensors that measure the rotation of the wheels. The maximum speed indicated on the speedometer is typically the maximum safe speed at which the car's components can operate without risking damage or safety issues. Trying to exceed this speed would strain the engine, transmission, and other components, potentially causing mechanical failure or loss of control.
Does tire size change speed?
It does not change the actual speed of a vehicle but changing tire size can affect the accuracy of the speedometer.
What would cause the speedometer to be off 5 miles an hr if everything is ariginal?
If the speedometer is reading 5 miles per hour faster than the actual speed and everything is original, it could be due to tire size differences. If the tires are not the manufacturer-recommended size, they can affect the accuracy of the speedometer. Additionally, wear and tear on the speedometer gear or issues with the vehicle's speed sensor could also contribute to inaccurate readings. Lastly, variations in the calibration of the speedometer itself may lead to discrepancies.

Will smaller tires show speed is less the actual?
Yes, it is obvious that if the radius of tire is small than it effect on the speed of the car. Smaller tires will show the speed on the speedometer more than actual.
