The 215/50R17 is a common tire size for midsize sedans such as Toyota Camry, Honda Accord, and Hyundai Sonata.
With a 107.5 mm sidewall (50% aspect ratio), this tire offers a balanced blend of ride comfort and handling precision — versatile for both city driving and spirited cornering.
Compared to the baseline 225/50R17, this tire's overall diameter differs by -1.5% — a speedometer calibrated for 225/50R17 would read 101.5 km/h at an actual 100 km/h.
Fitted to the Kia Cerato/Forte (YD/BD) and Chevrolet Bolt EV (2017-2023). Load index 91W or 95V reinforced. A frequent +1 upsizing target from 205/55R16 with minimal overall-diameter change.
Mainstream sedan sizes balance compound longevity against light all-season handling. When replacing, match the OE speed rating (H or V on most trims) — installing a lower rating voids many manufacturer load-test certifications and is illegal on autobahn-rated vehicles. Wheel-well clearance is rarely a concern at this rim diameter; speedometer drift across factory alternatives stays well inside the ±3% legal window.
