Vehicles equipped with power to all four wheels simultaneously require specific considerations when a single tire needs replacement. This involves factors beyond simply matching the tire size. For instance, maintaining uniform tire circumference across all four wheels is critical for the proper function of the drivetrain. Differences, even seemingly minor ones due to wear, can lead to premature wear and tear on differentials and other drivetrain components.
Preserving the integrity of the all-wheel-drive system through proper tire maintenance contributes significantly to vehicle longevity and performance. Historically, matching tire circumference was less critical on part-time four-wheel-drive systems. However, the prevalence of modern all-wheel-drive systems, often electronically controlled and active at all times, necessitates careful attention to tire condition and replacement procedures. Neglecting these considerations can result in costly repairs and diminished vehicle performance.
