The 225/55R16 is a common tire size for midsize sedans such as Toyota Camry, Honda Accord, and Hyundai Sonata.
With a 123.8 mm sidewall (55% 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 205/55R16, this tire's overall diameter differs by +3.5% — a speedometer calibrated for 205/55R16 would read 96.6 km/h at an actual 100 km/h.
Fitted to various premium-sedan 16" replacement packages where a wider tread on a comfort-oriented sidewall is preferred. Load index 95V or 99W reinforced. Wider 225 mm at this aspect ratio gives strong straight-line stability for highway-oriented sedans.
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.
