Comparison
205/50 R16 vs 205/60 R15
205/60 R15 drops the rim from 16 to 15 inches versus 205/50 R16, trading wheel size for taller sidewall. This swap shifts overall diameter slightly from OEM.
Expect a slight but noticeable shift in indicated speed compared to the original tires. The taller sidewall adds cushioning over potholes and rougher roads, with a softer overall ride. Minus-sizing keeps replacement costs down and opens up a wider range of winter and all-terrain tires. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakePractical direction for winter wheels, chains, or rougher pavement where cushioning matters.
Quick math: 205/60 R15 is 15.6 mm taller than 205/50 R16, shifting the speedometer by +2.55%.

Speedometer impact
At a true 100 km/h, your dashboard will read 102.6 km/h after switching to 205/60 R15 — a +2.55% 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 +7.8 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.
