Changing tire sizes affects more than just appearance. Even a 3% change in overall diameter can impact your speedometer accuracy, fuel economy, and vehicle handling. Plus-sizing (larger wheels with lower-profile tires) improves handling but may reduce ride comfort.
Your vehicle's ABS, traction control, and stability systems are calibrated for specific tire dimensions. Significant changes can affect their performance and potentially void warranties.
Same wheel size, different tire dimensions. Maintains ride quality while potentially improving performance.
Increase wheel diameter by 1 inch, decrease sidewall height. Improved handling, slightly firmer ride.
Increase wheel diameter by 2 inches, lower profile tires. Better handling but firmer ride, higher cost.
Increased width without diameter change. Better grip but potential for increased road noise and cost.
