Comparison
215/50 R16 vs 225/50 R16
On the same 16-inch wheel, 225/50 R16 grows the section width by 10 mm versus 215/50 R16. This sizing approach shifts overall diameter slightly from OEM. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakeUseful when extra dry grip and stance matter more than a small fuel-economy hit.
Quick math: 225/50 R16 is 10.0 mm taller than 215/50 R16, shifting the speedometer by +1.61%.

Speedometer impact
At a true 100 km/h, your dashboard will read 101.6 km/h after switching to 225/50 R16 — a +1.61% 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 +5.0 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.
