The 215/45R17 is a common tire size for midsize sedans such as Toyota Camry, Honda Accord, and Hyundai Sonata.
With a 96.8 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 -4.8% — a speedometer calibrated for 225/50R17 would read 105.0 km/h at an actual 100 km/h.
OE on the Subaru Impreza WRX (GD/GG, 2002-2007) and various compact sport-sedan 17" packages. Load index 87W or 91Y reinforced. Common compact sport-sedan fitment — high-speed rating availability (W/Y) is the broadest at this size.
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.
