Comparison
215/70 R15 vs 225/55 R16
Plus-sizing from 215/70 R15 to 225/55 R16 keeps overall diameter close to factory while opening room for a larger 16-inch wheel. This wheel and tire pairing moves rolling diameter well outside the usual OEM tolerance. The shorter sidewall gives the tire a firmer, more responsive feel and sharpens steering input.
Indicated speed will drift far enough that recalibration is worth considering. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.
Quick math: 225/55 R16 is 28.1 mm shorter than 215/70 R15, shifting the speedometer by -4.12%.

Speedometer impact
At a true 100 km/h, your dashboard will read 95.9 km/h after switching to 225/55 R16 — a -4.12% 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 -14.1 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.
