To adjust your speedometer for bigger tires on your F150, you will need to purchase a speedometer recalibration device. Once you have this device, follow the instructions that come with it to recalibrate your speedometer. Generally, you will need to drive your truck at a certain speed for a specific amount of time while the device is connected to your truck’s computer.
After recalibrating, your speedometer should be accurate for the new tire size.
- Drive your F150 around for a bit to get an accurate measurement of the new tire size
- Find the Odometer/Trip odometer reset knob, typically located on the left side of the instrument cluster above the steering column
- Press and hold in the reset knob while turning on the ignition switch
- The speedometer should now read “0”
- Release the knob and drive normally
- The speedometer will automatically adjust itself to reflect your new tire size within a few miles

Can You Adjust Your Speedometer for Bigger Tires?
If you have bigger tires on your car, you may need to adjust your speedometer. The reason for this is that the circumference of the tire affects the number of rotations per mile, and therefore how fast you are actually going. If you don’t adjust your speedometer, it will read lower than your actual speed, which can be dangerous.
There are a few ways to adjust your speedometer for bigger tires. One way is to use a GPS system. You can input the new circumference of your tires into the GPS, and it will calculate your new speeds for you.
Another way is to use a tire size calculator online. You can input the information about your car and tires, and it will tell you what size speedometer gear you need to buy. Or, if you’re feeling ambitious, you can do the math yourself!
Just divide the circumference of your new tires by that of your old ones, and multiply that number by Your current speed reading. This will give you an accurate reading on your new setup.
No matter which method you choose, adjusting your speedometer for bigger tires is important for safety on the roadways!
How Much Does It Cost to Recalibrate Speedometer?
If your speedometer is inaccurate, it needs to be recalibrated. Depending on the severity of the inaccuracy, this may be a simple process that you can do yourself or it may require professional assistance.
In general, most speedometers can be manually adjusted with a few tools that you likely already have in your home garage.
For more severe cases, however, you’ll need to take your car to a professional mechanic or dealership service center for recalibration.
The cost of recalibrating your speedometer will depend on the method used and who does the work. For a basic manual adjustment, you can expect to pay around $50-$100.
If you need to take your car to a mechanic or dealership, the cost will be higher, typically starting at around $200.
Can Ford Calibrate a Speedometer?
If your speedometer is reading inaccurately, or if you’ve made modifications that have affected your vehicle’s speed, you may need to have the speedometer recalibrated. Here’s what you need to know about getting your speedometer calibrated.
Most vehicles are equipped with a sensor that sends a signal to the computer to indicate how fast the vehicle is moving.
This information is then used by the computer to adjust various systems in the car, including the speedometer. If this sensor becomes damaged or dislodged, it can cause the speedometer to read inaccurately. In some cases, making modifications to your vehicle (like changing tires or installing a new transmission) can also affect the accuracy of the speedometer and require calibration.
Fortunately, calibrating aspeedometer is generally a pretty straightforward process. Many Ford dealerships offer this service, and it can usually be completed in just a few minutes. The technician will simply hook up a special device to your car’s computer and make any necessary adjustments so that your speedometer reads correctly again.
How Do I Change My Speedometer Accuracy?
There are a couple different ways that you can change your speedometer accuracy. You can either adjust the settings in your car, or you can purchase a device that will attach to your car and do the adjusting for you.
If you want to adjust the settings in your car, you will need to find the speedometer calibration setting.
This is usually located in the vehicle information menu. Once you have found it, simply enter the new desired speed that you want your speedometer to read. Keep in mind that this may not be 100% accurate, as there are other factors that can affect your speed (such as tire size).
If you would rather purchase a device to do the adjusting for you, there are many options available on the market. These devices typically attach to your car’s data port (usually located under the dash) and then allow you to select the new desired speed on their display. Again, keep in mind that this may not be 100% accurate due to other factors.
