The 235/45R17 is a common tire size for midsize sedans such as Toyota Camry, Honda Accord, and Hyundai Sonata.
With a 105.8 mm sidewall (45% 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 -2.1% — a speedometer calibrated for 225/50R17 would read 102.1 km/h at an actual 100 km/h.
OE on the Mercedes-Benz C-Class (W203) AMG-Line, VW Passat (B5.5/B6) sport trim and Toyota 86 (ZN6, 2016+). Load index 94W or 97Y reinforced. Wider than 225/45R17 — requires 8.0" wheel width minimum to prevent bulged sidewalls.
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.
