Comparison
205/60 R16 vs 205/70 R15
Switching from 205/60 R16 to 205/70 R15 steps down to a 15-inch wheel — a familiar move for winter and dedicated all-terrain sets. This swap trims or stretches rolling diameter by a small margin. Extra sidewall absorbs impacts more readily — a sensible bias for daily commuting and broken pavement.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. Diameter change stays inside the conservative ±3% safety window — an OEM-safe fitment on most vehicles.
TakePractical direction for winter wheels, chains, or rougher pavement where cushioning matters.
Quick math: 205/70 R15 is 15.6 mm taller than 205/60 R16, shifting the speedometer by +2.39%.

Speedometer impact
At a true 100 km/h, your dashboard will read 102.4 km/h after switching to 205/70 R15 — a +2.39% 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.
