Let’s be honest, sometimes you just need to upgrade your ride. Maybe you’re looking for a more aggressive look with bigger tires, or perhaps you’re aiming for a smoother ride with a smaller profile. Whatever your reason, changing tire size can impact your car’s performance and fuel efficiency. But before you go ahead and swap those tires, you might be wondering, “Can I just change the tire size on my car’s computer?”
What Does it Mean to Modify Tire Size on a Scan Tool?
You’re not alone in wondering if a scan tool can directly change your car’s tire size. It’s a common question, but understanding the answer requires diving a little deeper.
From a technical standpoint, scan tools can’t magically alter the physical size of your tires. It’s about adjusting the vehicle’s computer to recognize the new tire size, which ultimately affects how the car calculates things like:
- Speedometer Accuracy: The computer relies on wheel rotation data to calculate your speed. Different tire sizes affect how many rotations per mile your car makes, so a change in tire size could throw off the speedometer reading.
- Traction Control and ABS: Your car’s stability systems use wheel speed information to adjust brake pressure and throttle response. Changing tire size can impact these calculations, potentially leading to issues with traction control and Anti-lock Braking System (ABS).
- Fuel Economy: Larger tires often increase rolling resistance, leading to a slight decrease in fuel efficiency. Conversely, smaller tires may reduce rolling resistance, improving fuel economy.
So, How Can You Adjust Tire Size?
Most modern vehicles have a “Tire Size” parameter within their software. This is where you can tell the computer about the new tire dimensions.
Here’s how it usually works:
- Find the Tire Size Parameter: Using a compatible scan tool, you’ll need to navigate to the vehicle’s software. This involves selecting your car’s make and model and finding the specific module related to tire size.
- Input the New Tire Size: You’ll likely be prompted to enter the tire’s dimensions, including width, aspect ratio, and rim diameter.
- Save the Changes: Once you’ve entered the new tire information, you need to save it to the vehicle’s computer.
Important Note: Not all scan tools can access and modify the tire size parameter. Some tools might only be able to read the information, while others might offer limited functionality.

The specific scan tools that can modify tire size vary depending on the vehicle’s make and model. However, here are some common options:

Tips for Changing Tire Size:
- Consult Your Owner’s Manual: Your owner’s manual may provide information about recommended tire sizes for your vehicle.
- Check Your Local Laws: Some regions have regulations regarding tire size modifications.
- Consider the Impact on Performance: Changing tire size can affect your car’s handling, acceleration, and braking.
- Calibrate Your Speedometer: After making a change, you may need to have your speedometer recalibrated to ensure accuracy.
FAQs About Tire Size Modification:
Can I change the tire size myself?
While some DIY enthusiasts might attempt it, it’s recommended to have a professional mechanic or a qualified individual modify your car’s tire size.
Will changing tire size void my warranty?
In most cases, tire size modifications are unlikely to void your warranty. However, it’s best to consult your dealership or car manufacturer to confirm.
What if my scan tool can’t modify tire size?
If your scan tool lacks the functionality to modify tire size, you may need to consult a mechanic who has access to the necessary equipment and software.
Can I use any tire size I want?
You should select a tire size within the range recommended by your car manufacturer. Using inappropriate tire sizes can lead to performance and safety issues.
