What This Swap Means
Shorter sidewall: The 11.2mm decrease in sidewall height improves steering response and cornering precision. However, ride quality becomes firmer and the wheels are more vulnerable to pothole damage. This is a common trade-off when upsizing wheels (plus-sizing).
Ground clearance: Increases by 1.4mm, providing slightly better approach angles for off-road driving and speed bump clearance.
