Comparison
205/50 R17 vs 225/50 R16
Going from 205/50 R17 to 225/50 R16 is a minus-1 setup that adds sidewall on a smaller 16-inch wheel. This sizing approach keeps overall diameter very close to stock.
Speedometer drift stays small enough that most drivers won't notice it day to day. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting. The smaller wheel is also lighter and easier to find affordable winter rubber for. Diameter change stays inside the conservative ±3% safety window — an OEM-safe fitment on most vehicles.
TakeTypical choice for a dedicated winter or off-road setup where extra sidewall pays off.
Quick math: 225/50 R16 is 5.4 mm shorter than 205/50 R17, shifting the speedometer by -0.85%.

Speedometer impact
At a true 100 km/h, your dashboard will read 99.2 km/h after switching to 225/50 R16 — a -0.85% 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 -2.7 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.
