Yes. To do so, you will need your transmission gear ratios, your differential gear ratio and your tire circumference. You can derive the tire circumference by mutliplying its diameter by 3.1416 (pi).
Example: At highway speed your RPM is 2000. Say your overdrive (5th gear) is 0.84:1, your differential gear ratio is 3.73:1 and your tire circumference for a P215/75R15 is 87". First divide the RPM by the first ratio (.84) which gives you 2380 RPMS. Then divide by the differential ratio of 3.73 gives you 638.3 RPM (Wheel speed). You speed is 87"x 638.3 = 55,532 inches per minute or 52.6 MPH.
Hope that helps!

What is the tool use to measure speed?
An anemometer is used to measure wind speed. A Pitot Tube is used to infer speed in an aeroplane,. A speedometer in an ordinary car, and a microwave or laser radar in a Police car.
How do you measure efficiency?
Efficiency= Mechanical Advantage Speed ratio X100 Mechanical advantage divided by speed radio X (times) 100
What is the speed of a car?
the speed is a unit of measure used to describe the rate of movement. As in the car went 35 mph while it drove down the street.
Is CPU speed a ratio or interval?
ratio
What is the Speed Ratio of a bicycle?
The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.
How do you measure a speed of a car?
speed = distance divided by time
What does the speed of the car depend on?
Horse power and gear ratio.
How do you measure the speed of a car without a speedometer?
do you measure how far it will go and then time it
Speed range of 2'nd gear in manual transmission cars?
I want to know how a manual transmission gear ratio worked. What ratio give the car mor power and what give the car mor speed.
What is the tool use to measure speed?
An anemometer is used to measure wind speed. A Pitot Tube is used to infer speed in an aeroplane,. A speedometer in an ordinary car, and a microwave or laser radar in a Police car.
What factors effect the speed of the car?
Aerodynamics, horse power, gear ratio,
Does the speedometerof a car read average speed or instantaneous speed?
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.
How much force is a Mach?
Mach is a unit used to measure the speed of an object in relation to the speed of sound in the medium it is traveling through. It does not measure force, but rather the ratio of an object's speed to the speed of sound.
What does the odometer and speedometer of a car measure?
Odos measure distance travelled, speedos measure speed at that moment.
Why are speed ratio and mechanical advantage never the same?
Speed ratio and mechanical advantage are not the same because they are inversely related. Speed ratio is a measure of how much the input speed is amplified or reduced by a machine, while mechanical advantage is a measure of how much the input force is amplified or reduced. A machine that increases speed will have a mechanical advantage less than one, while a machine that increases force will have a mechanical advantage greater than one.
What i the ratio of the distance an object moves to the amount of time it moves?
The ratio of distance moved to the time taken to move that distance is the speed of the object. Speed is a measure of how quickly an object changes its position. Mathematically, speed = distance/time.
Kilometers or meters or etc to measure a car?
speed.. distance..
