Comparison
205/60 R15 vs 215/55 R16
Switching from 205/60 R15 to 215/55 R16 is a plus-1 upgrade that wraps a shorter sidewall around a larger 16-inch wheel. This alternative fitment moves rolling diameter a touch off the original spec. The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. Less sidewall flex usually translates to crisper turn-in and a slightly stiffer ride over rough pavement. Diameter change stays inside the conservative ±3% safety window — an OEM-safe fitment on most vehicles.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.
Quick math: 215/55 R16 is 15.9 mm taller than 205/60 R15, shifting the speedometer by +2.54%.

At a true 100 km/h, your dashboard will read 102.5 km/h after switching to 215/55 R16 — a +2.54% 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 +7.9 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.
