The 225/45R17 is a common tire size for midsize sedans such as Toyota Camry, Honda Accord, and Hyundai Sonata.
With a 101.3 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 -3.4% — a speedometer calibrated for 225/50R17 would read 103.5 km/h at an actual 100 km/h.
Standard OE on the BMW 3 Series (E90/E92) M-Sport front (staggered with 255/40R17 rear), VW Golf Mk6 GTI and Honda Civic Si (FG2). Load index 91W or 94Y reinforced. The benchmark performance-sedan size — every premium tire maker stocks it in summer and all-season UHP compounds.
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.
