Comparison
195/50 R16 vs 205/55 R16
205/55 R16 is a wider variation of 195/50 R16 on the same 16-inch rim, adding 10 mm of tread footprint. This wheel and tire pairing noticeably changes overall diameter compared to OEM. Extra sidewall absorbs impacts more readily — a sensible bias for daily commuting and broken pavement.
Speedometer error is large enough that recalibration is effectively required for accurate readings. The diameter gap exceeds 5%, which can affect speedometer accuracy, ABS calibration and final gearing — review with a professional first.
TakeTreat as a serious modification — verify clearance, recalibrate the speedometer and reassess load capacity.
Quick math: 205/55 R16 is 30.5 mm taller than 195/50 R16, shifting the speedometer by +5.07%.

Speedometer impact
At a true 100 km/h, your dashboard will read 105.1 km/h after switching to 205/55 R16 — a +5.07% offset. Use the speedometer error calculator to recheck for other indicated speeds, and the speedometer error guide for the full background.
Ground clearance change
The new tire's half-diameter changes ride height by +15.3 mm. Small differences are absorbed by suspension travel, but anything beyond ±10 mm can affect headlight aim, fender clearance and bump-stop margin. See the plus-sizing guide before committing.
