Comparison
205/65 R15 vs 215/50 R16
Plus-sizing from 205/65 R15 to 215/50 R16 keeps overall diameter close to factory while opening room for a larger 16-inch wheel. This tire combination moves rolling diameter well outside the usual OEM tolerance. Indicated speed will drift far enough that recalibration is worth considering. Expect a more planted steering feel, at the cost of some of the cushioning a taller sidewall provides. 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: 215/50 R16 is 26.1 mm shorter than 205/65 R15, shifting the speedometer by -4.03%.

Speedometer impact
At a true 100 km/h, your dashboard will read 96.0 km/h after switching to 215/50 R16 — a -4.03% 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 -13.1 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.
