It does not change the actual speed of a vehicle but changing tire size can affect the accuracy of the speedometer.
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.
No but, tire size does effect wheel speed sensors.
How far off is it? Did you change tire/wheel size? Bad speed sensor.
Yes not only does it change the speed of the vehicle, it will also affect the odometer and the MPGs the vehicle is getting (not for the better usually). its always best the check what tire size the vehicle manufacturer recommends for your specific vehicle, the size is listed on a spec sticker on the drivers side door edge or the frame near the latch plate. you want to either match that tire size or get a tire of equal diameter - IE. total height. To see the difference yourself with your tire size change check this website out - just six steps to figure out speedometer changes and tire height differences. http://www.net-comber.com/tirecalc.html
yes!! of course, because the shaft is designed to rotate a certain speed, according to the car advancing speed.
IF you change the tire size from OE either bigger or smaller there will definatly be a change from the actual speed you are going. Not a huge difference but by maybe 1-3 mph depending on your tire size
just go to a tire shop. But the normal rim size is 16 and tire can change size.
A change in overall tire height will change speedometer accuracy.
Without you telling us the entire number, we can't say ! - Speed code is at end of the full number
it will be ur tire as it is the last thing to touch the road
