Comparison
225/55 R16 vs 225/60 R16
Going from 225/55 R16 to 225/60 R16 raises the aspect ratio by 5 points on the same 16-inch wheel. This sizing approach noticeably changes overall diameter compared to OEM. Extra sidewall absorbs impacts more readily — a sensible bias for daily commuting and broken pavement.
The speedometer error is noticeable and may warrant a recalibration if you rely on indicated speed. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeA comfort-leaning direction that's easier on wheels and suspension over rough surfaces.
Quick math: 225/60 R16 is 22.5 mm taller than 225/55 R16, shifting the speedometer by +3.44%.

Speedometer impact
At a true 100 km/h, your dashboard will read 103.4 km/h after switching to 225/60 R16 — a +3.44% 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 +11.3 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.
