The 185/55R16 is a common tire size for midsize sedans such as Toyota Camry, Honda Accord, and Hyundai Sonata.
With a 101.8 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 103.6 km/h at an actual 100 km/h.
OE on the Honda Fit Sport (GE/GK), Toyota Yaris (XP130) higher trims and Mazda 2 Sport (DE/DJ). Load index 83V or 87V reinforced. Narrow 185 mm tread on a 16" rim is unusual — most replacements come from European compact-sport catalogues only.
Narrow profiles in this group emphasize ride comfort, rolling resistance and snow-chain compatibility over cornering grip. Owners replacing these sizes should prioritize tread-life and fuel-economy ratings on the EU label — UHP compounds add little value on platforms tuned for 95 km/h cruise speeds, and the extra rolling resistance shortens range.
