Maintaining proper tire dimensions is crucial for vehicle safety and performance. Slight variations from the manufacturer’s recommended size can impact speedometer accuracy, odometer readings, anti-lock brake system (ABS) function, traction control, and overall handling. For example, a larger diameter tire will rotate fewer times per mile than a smaller one, potentially causing the speedometer to underreport the vehicle’s actual speed. This seemingly small discrepancy can have significant implications for both safety and compliance with traffic laws.
Historically, limited tire size options made adherence to manufacturer specifications relatively straightforward. However, the proliferation of tire sizes and aftermarket modifications has made understanding permissible deviations increasingly important. Correctly sized tires ensure optimal vehicle performance, prevent premature wear and tear on drivetrain components, and contribute to fuel efficiency. Ignoring these considerations can lead to costly repairs and compromise safety.
