Note 1: 2025 718 Boxster uses the supported ordinary/base375 mm/10 wheel. Manufacturer evidence explicitly distinguishes optional360 mm, and the separately retained GTS4.0 is360 mm/9. S375 mm/10 and StyleEdition375 mm/9 remain separate observations. Apply the owner base-wheel rule; do not add optional/sport versions to another broad size or average the values. No applicable positive nonround restriction is established for the accepted application; unknown is not certified round. Return to measurement
