Comparison
215/50 R17 vs 225/50 R16
225/50 R16 drops the rim from 17 to 16 inches versus 215/50 R17, trading wheel size for taller sidewall. This swap trims or stretches rolling diameter by a small margin.
Expect a slight but noticeable shift in indicated speed compared to the original tires. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. The smaller wheel is also lighter and easier to find affordable winter rubber for. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakePractical direction for winter wheels, chains, or rougher pavement where cushioning matters.
Quick math: 225/50 R16 is 15.4 mm shorter than 215/50 R17, shifting the speedometer by -2.38%.

Speedometer impact
At a true 100 km/h, your dashboard will read 97.6 km/h after switching to 225/50 R16 — a -2.38% 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 -7.7 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.
