Comparison
175/65 R15 vs 215/50 R16
Plus-sizing from 175/65 R15 to 215/50 R16 keeps overall diameter close to factory while opening room for a larger 16-inch wheel. This setup shifts overall diameter slightly from OEM. Less sidewall flex usually translates to crisper turn-in and a slightly stiffer ride over rough pavement.
Expect a slight but noticeable shift in indicated speed compared to the original tires. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.
Quick math: 215/50 R16 is 12.9 mm taller than 175/65 R15, shifting the speedometer by +2.12%.

Speedometer impact
At a true 100 km/h, your dashboard will read 102.1 km/h after switching to 215/50 R16 — a +2.12% 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 +6.4 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.
