Comparison
205/60 R16 vs 225/60 R16
Stepping from 205/60 R16 to 225/60 R16 keeps the 16-inch wheel but widens the section by 20 mm. This setup moves rolling diameter well outside the usual OEM tolerance. Indicated speed will drift far enough that recalibration is worth considering. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeReasonable performance-leaning swap as long as fender and suspension clearance check out.
Quick math: 225/60 R16 is 24.0 mm taller than 205/60 R16, shifting the speedometer by +3.68%.

Speedometer impact
At a true 100 km/h, your dashboard will read 103.7 km/h after switching to 225/60 R16 — a +3.68% 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 +12.0 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.
