Once you’ve installed larger tires on your GMC Sierra 2500 HD, you might notice that your speedometer readings are no longer accurate. This is because the vehicle’s computer is calibrated for the original tire size, causing discrepancies in speed readings. Rough Country has developed an effective solution with their Speedometer Calibrator. This device directly connects to your vehicle’s Diagnostic Link Connector Port, enabling you to effortlessly update your speedometer to reflect the new tire size. Not only does it adjust your speedometer, but it also recalibrates your electronic stability control and updates your ECM shift points to align with the larger tires, ensuring accurate performance and a safe driving experience.
