Comparison
225/60 R17 vs 235/60 R16
Going from 225/60 R17 to 235/60 R16 is a minus-1 setup that adds sidewall on a smaller 16-inch wheel. This alternative fitment trims or stretches rolling diameter by a small margin. The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. 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: 235/60 R16 is 13.4 mm shorter than 225/60 R17, shifting the speedometer by -1.91%.

At a true 100 km/h, your dashboard will read 98.1 km/h after switching to 235/60 R16 — a -1.91% 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 -6.7 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.
