The 205/45R17 is a common tire size for midsize sedans such as Toyota Camry, Honda Accord, and Hyundai Sonata.
With a 92.3 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 -6.2% — a speedometer calibrated for 225/50R17 would read 106.6 km/h at an actual 100 km/h.
OE on the Mini Cooper S (R56) and Honda Civic Si Sedan (FA5/FG2). Load index 84V or 88V reinforced. Low 92.25 mm sidewall is borderline for poor pavement — many owners step up to 205/50R17 for daily use.
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.
