Calculate a Speedometer With Higher quality Tires
Provided you've ever been pulled over when your speedometer reads one tool and an officer's radar gun reads another, then you already recognize this factuality: Changing the magnitude of your tires throws the reading of your speedometer off. Most machine speedometers are calibrated based on the hurry of the transmission and the revolutions per mile of a particular amount tire. On the contrary whether you can figure outside how yet faster you are travelling than your van thinks you are, you can calculate your precipitation based on your speedometer reading.
Instructions
1. Degree your senile tire vastness (A). Add N back to S for your new total (N+S=T). In other words, 100 + 5 = 105 miles per hour.
4. Take a reading from your speedometer (S). Figure out the increase or decrease in speed by dividing that number by the answer from step 3 (S/C=N). For instance, if your speedometer reads that you are traveling 100 miles per hour, and C=500 (5 percent bigger) then 100/500 =5 miles per hour faster.
5. This is the standard-size tire placed on the vehicle by the manufacturer.2. Degree your new tire size (B).3. Divide the larger number by the smaller number (A/B=C or B/A=C).
