Comparison
225/55 R18 vs 225/60 R16
Going from 225/55 R18 to 225/60 R16 is a minus-2 setup that adds sidewall on a smaller 16-inch wheel. This swap swings rolling diameter far enough to feel on the road. The taller sidewall adds cushioning over potholes and rougher roads, with a softer overall ride.
The speedometer error is noticeable and may warrant a recalibration if you rely on indicated speed. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakeTypical choice for a dedicated winter or off-road setup where extra sidewall pays off.
Quick math: 225/60 R16 is 28.3 mm shorter than 225/55 R18, shifting the speedometer by -4.02%.
