The Side Effects of Installing Larger Than Stock Tires and Wheels on Your Vehicle

Upgrading to larger than stock tires and wheels is a popular modification among truck/SUV enthusiasts. It enhances the vehicle's aesthetic appeal and can improve off-road performance. However, this upgrade isn't without its drawbacks. In this blog, we'll explore the side effects of installing larger than stock tires and wheels, how it affects power delivery, the reasons behind this modification, and the importance of using a speedometer calibration tool to ensure accurate speed readings.

Side Effects of Larger Than Stock Tires and Wheels

An Inaccurate Speed Reading

One of the most immediate effects of larger than stock tires and wheels is an inaccurate speed reading. Since speedometers are calibrated based on the stock tire size, larger tires cause the speedometer to display a slower speed than the vehicle is actually traveling. This can lead to unintentional speeding and potential safety hazards.

Reduced Fuel Efficiency

Larger than stock tires and wheels have more rolling resistance, which means the engine has to work harder to move the vehicle. This increased effort results in higher fuel consumption and reduced fuel efficiency. Drivers may notice they need to fill up more often after upgrading their tires.

Decreased Acceleration and Braking Performance

The added weight and increased rotational mass of larger than stock tires and wheels can negatively impact a vehicle's acceleration and braking performance. The engine may struggle to deliver the same level of power, leading to slower acceleration. Additionally, the braking system has to work harder to stop the vehicle, which can lead to increased brake wear.

Suspension and Steering Impact

Larger than stock tires and wheels can place additional stress on a vehicle's suspension and steering components. This extra strain can lead to premature wear and tear, potentially resulting in costly repairs down the line. The handling characteristics of the vehicle may also be affected, making it feel less responsive.

The Appeal of Larger Than Stock Tires and Wheels

Despite these drawbacks, many people choose to install larger than stock tires and wheels for several reasons:

Enhanced Aesthetic Appeal

Larger than stock tires and wheels can dramatically change the appearance of a vehicle, giving it a more aggressive and commanding presence. This visual upgrade is often a major motivating factor for car enthusiasts.

Improved Off-Road Performance

For those who enjoy off-roading, larger than stock tires provide better ground clearance and improved traction on rough terrain. This can enhance the vehicle's capability to navigate challenging trails and obstacles.

Better Handling in Certain Conditions

In some cases, larger than stock tires can improve handling in specific driving conditions, such as snow or mud. The increased surface area provides better grip and stability, which can be beneficial in adverse weather conditions.

The Importance of Speedometer Calibration

Using a Speedometer Calibration Tool

Given the changes larger than stock tires and wheels make to your vehicle, it's essential to recalibrate the speedometer to ensure an accurate reading. This is where a speedometer calibration tool comes in handy. The Hypertech Speedometer Calibrator is a reliable and user-friendly solution designed to recalibrate the vehicle computer for an accurate speed reading for these modifications.

Benefits of Speedometer Calibration

1.     Accurate Speed Readings: Ensures that your speedometer displays the correct speed, preventing unintentional speeding and enhancing road safety.

2.     Compliance with Legal Standards: Accurate speed readings help you avoid speeding tickets and comply with traffic regulations.

3.     Improved Vehicle Performance: Proper calibration can optimize your vehicle's performance by ensuring the engine and transmission are operating correctly.


While upgrading to larger than stock tires and wheels offers several benefits, it's important to be aware of the potential side effects. From an inaccurate speed reading to reduced fuel efficiency, understanding these impacts can help you make informed decisions about your vehicle modifications. To maintain an accurate speed reading and ensure optimal vehicle performance, using a speedometer calibration tool like the Hypertech Speedometer Calibrator® is essential. This performance product simplifies the calibration process, ensuring your speed reading is accurate and reliable.
