Comparison
225/55 R17 vs 235/60 R16
Going from 225/55 R17 to 235/60 R16 is a minus-1 setup that adds sidewall on a smaller 16-inch wheel. This wheel and tire pairing keeps overall diameter very close to stock.
The speedometer offset is mild and well inside what most cars can tolerate without recalibration. The taller sidewall adds cushioning over potholes and rougher roads, with a softer overall ride. 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.
TakeTypical choice for a dedicated winter or off-road setup where extra sidewall pays off.
Quick math: 235/60 R16 is 9.1 mm taller than 225/55 R17, shifting the speedometer by +1.34%.

Speedometer impact
At a true 100 km/h, your dashboard will read 101.3 km/h after switching to 235/60 R16 — a +1.34% 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 +4.6 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.
