Comparison
225/45 R18 vs 225/60 R16
Going from 225/45 R18 to 225/60 R16 is a minus-2 setup that adds sidewall on a smaller 16-inch wheel. This alternative fitment shifts overall diameter slightly from OEM. Extra sidewall absorbs impacts more readily — a sensible bias for daily commuting and broken pavement.
Expect a slight but noticeable shift in indicated speed compared to the original tires. 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: 225/60 R16 is 16.7 mm taller than 225/45 R18, shifting the speedometer by +2.53%.
