Comparison
215/50 R16 vs 225/55 R16
On the same 16-inch wheel, 225/55 R16 grows the section width by 10 mm versus 215/50 R16. This sizing approach noticeably changes overall diameter compared to OEM. The dashboard speed will be significantly off — plan on recalibration before daily use. The taller sidewall adds cushioning over potholes and rougher roads, with a softer overall ride. The diameter gap exceeds 5%, which can affect speedometer accuracy, ABS calibration and final gearing — review with a professional first.
TakeRecommended only after a professional fitment check and speedometer recalibration.
Quick math: 225/55 R16 is 32.5 mm taller than 215/50 R16, shifting the speedometer by +5.23%.

Speedometer impact
At a true 100 km/h, your dashboard will read 105.2 km/h after switching to 225/55 R16 — a +5.23% 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 +16.3 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.
