The 205/50R16 is a common tire size for midsize sedans such as Toyota Camry, Honda Accord, and Hyundai Sonata.
With a 102.5 mm sidewall (50% 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 -3.2% — a speedometer calibrated for 205/55R16 would read 103.4 km/h at an actual 100 km/h.
Fitted to the Mazda 3 (BK) and Mazda MX-5 (NC) base. Load index 87W or 91W reinforced for hot-climate use. Wheel widths 6.5-7.5" — too narrow at 6.0" causes uneven shoulder wear.
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.
