Comparison
225/60 R16 vs 235/45 R17
Switching from 225/60 R16 to 235/45 R17 is a plus-1 upgrade that wraps a shorter sidewall around a larger 17-inch wheel. This wheel and tire pairing noticeably changes overall diameter compared to OEM.
Indicated speed will drift far enough that recalibration is worth considering. Less sidewall flex usually translates to crisper turn-in and a slightly stiffer ride over rough pavement. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. Many drivers pick this direction primarily for appearance — the bigger rim simply looks more aggressive. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.
Quick math: 235/45 R17 is 33.1 mm shorter than 225/60 R16, shifting the speedometer by -4.89%.

Verdict: warning
Between 3% and 5% — noticeable speedometer drift; recalibration may be advisable.
Speedometer impact
At a true 100 km/h, your dashboard will read 95.1 km/h after switching to 235/45 R17 — a -4.89% 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 -16.6 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.
