How to Calibrate Speedometer for Bigger Tires

If you have bigger tires on your car, it’s important to calibrate your speedometer so that it reflects the new size. Otherwise, you won’t be able to accurately gauge your speed and could end up getting a speeding ticket! Here’s how to do it:

1. Find out the circumference of your new tires. You can do this by measuring the diameter and then multiplying by 3.14. 2. Go to a website like and input the information about your tires.

This will give you the new speedometer reading for your car with bigger tires. 3. Adjust your speedometer accordingly! Most cars have a little knob on the back of the speedometer that you can turn to adjust the reading.

Hopefully this helps keep you from getting any unwanted speeding tickets!

Can I Calibrate My Speedometer for Larger Tires?

If you have larger tires on your vehicle, you may need to calibrate your speedometer. This is because the larger tires will cause your vehicle to travel a greater distance in a given amount of time than with smaller tires. As a result, your speedometer will read higher speeds than what you are actually traveling.

There are a few different ways that you can calibrate your speedometer for larger tires. One way is to use a GPS device to measure your actual speed and then adjust the reading on your speedometer accordingly. Another way is to look up the circumference of your new tires and compare it to the standard size tire.

Based on this comparison, you can calculate how much faster your vehicle is really going and adjust the speedometer readings accordingly. It’s important to make sure that your speedometer is accurate so that you don’t unintentionally break the law by speeding. If you’re not sure how to calibrate your speedometer, consult a professional mechanic or someone who is familiar with this process before proceeding.

How Do You Calibrate the Speedometer on a 2016 Chevy Silverado?

If your Chevy Silverado’s speedometer is not reading correctly, you may need to calibrate it. Depending on your model year, there are different ways to do this. For 2016 model years and newer:

1. Start the engine and let it idle in park for three minutes. 2. Turn off all accessories and make sure the transmission is in neutral. 3. Press and hold the trip odometer reset button while turning the ignition key to the “run” position without starting the engine.

Keep pressing the button until “P-0128” appears in the odometer/trip odometer display area (it may take up to 30 seconds). 4. Pressing the gas pedal slowly three times should change “P-0128” to “CAL”. If it does not, turn off the ignition and start over from step 2. If it does change to “CAL”, press and hold down on both arrow buttons next to the display at the same time for about five seconds until a chime sounds indicating that calibration has begun.

The truck will automatically drive itself through a series of tests during which you should keep your hands off of both pedals as well as the steering wheel – letting go of either one will cancel calibration mode and you’ll have to start over again from step 1 above if that happens. After completing its tests, your speedometer should be properly calibrated!

How Do You Measure Speedometer With Bigger Tires?

If you have bigger tires on your car, you may be wondering how to accurately measure your speedometer. There are a few different ways that you can do this, and each has its own benefits and drawbacks. The first method is to simply drive your car at a known speed, then measure the distance that you travel in a certain amount of time.

This method is relatively easy to do, but it can be inaccurate if you don’t know the exact size of your tires. Another drawback is that it can be difficult to find a straight stretch of road where you can safely maintain a consistent speed. The second method is to use a GPS device to track your speed.

This is more accurate than the first method, but it requires an investment in a GPS unit. Additionally, you’ll need to take the time to learn how to use the unit properly in order to get accurate readings. The third option is to visit a professional mechanic who can recalibrate your speedometer for you.

This option will ensure that your speedometer reading is accurate, but it will also cost money for the service. Additionally, you’ll need to make sure that you visit a reputable mechanic who knows how to properly recalibratespeedometers.

How Do I Get My Speedometer Calibrated?

If your speedometer is reading inaccurately, there are a few ways to get it calibrated. Depending on the severity of the error, you may be able to make a simple adjustment yourself or you may need to take it to a professional. If the error is less than 10%, you can try adjusting the speedometer cable.

To do this, find where the cable attaches to the speedometer head and loosen the retaining nut. Then, turn the head until the pointer is pointing at zero on the dial. Next, tighten the retaining nut and road test the vehicle to see if the calibration was successful.

If not, repeat the process until it is calibrated correctly. If your speedometer error is more than 10% or if adjusting the cable does not work, then you will need to take it to a professional for further diagnosis and repairs. They will likely hook up your car to a machine that can accurately measure your speed and make any necessary adjustments.

Speedometer Calibration – Adjust for Bigger Tires – Accurate Shifting & Fuel Economy


If you own a Chevy and have larger tires, you may need to calibrate your speedometer. This can be done by following these simple steps: 1. Park your Chevy on level ground and set the parking brake.

2. Place a jack under the front of the vehicle and raise it until the tires are clear of the ground. 3. Using a tape measure, measure the distance between the centers of two opposite wheel lugs. Write this measurement down.

4. Measure the circumference of one of the tires at its widest point. Write this measurement down as well. 5. divide the tire circumference by 2 pi (3.14).

This will give you the diameter of the tire in inches. Write this measurement down as well . Now multiply that number by 12 to convert it to feet .

So if your tire has a circumference of 80 inches, then its diameter is 25 inches (80 / 3.14 = 25). And 25 x 12 = 300 feet . This is how far your car will travel in one mile .

If you have larger than stock tires, then that number will be less than 5280 feet (one mile), and your speedometer will read slow . Conversely, if you have smaller than stock tires , then that number will be greater than 5280 feet , and your speedometer will read fast .
