Fitment comparison
205/70 R15versus225/60 R16
Δ Ø +8.4 mmSpeedo +1.26%OEM-safe
225/60 R16 stands taller than 205/70 R15 — bigger rolling diameter, slightly more clearance, calmer cruise revs.
225/60 R16 is a plus-1 alternative to 205/70 R15 — the bigger wheel shows through a thinner sidewall. This sizing approach lands within OEM rolling-diameter tolerance.
Dashboard speed shifts only marginally — within the noise of normal OEM tolerance. Less sidewall flex usually translates to crisper turn-in and a slightly stiffer ride over rough pavement. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting. Visually, the bigger wheel fills the arch and gives the car a more aggressive stance. 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.

Direct answer
Is 225/60 R16 OEM-safe?
Yes. Overall diameter changes by +1.26% versus 205/70 R15. OEM-safe. Speedometer, ABS, ESP and gearing remain inside the factory tolerance.
Direct answer
Will 225/60 R16 rub?
Borderline. Width changes by +20 mm and diameter by +8.4 mm. Borderline — check fender lip and inner strut clearance under load.
Direct answer
Does the speedometer change?
Yes — by +1.26%. Swapping 205/70 R15 for 225/60 R16 changes overall diameter, so at an indicated 100 km/h your true speed becomes 101.3 km/h. That's within the ±3% OEM tolerance — no recalibration needed.
Direct answer
Does lower sidewall affect comfort?
Yes — firmer ride. Sidewall changes by -8.5 mm (70% → 60%). Ride becomes firmer and steering sharper, but potholes and expansion joints hit harder and wheel damage risk rises.

Cluster preview
Within toleranceSpeedometer impact
At a true 100 km/h, your dashboard will read 101.3 km/h after switching to 225/60 R16 — a +1.26% offset. Use the speedometer error calculator for any indicated speed, and the speedometer error guide for the full background.
Ground clearance change
The new tire's half-diameter changes ride height by +4.2 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.
