Comparison
225/50 R16 vs 225/50 R17
Going from 225/50 R16 to 225/50 R17 steps up to a 17-inch rim while trimming sidewall to stay near OEM rolling diameter. This swap noticeably changes overall diameter compared to OEM.
The speedometer error is noticeable and may warrant a recalibration if you rely on indicated speed. Many drivers pick this direction primarily for appearance — the bigger rim simply looks more aggressive. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.
Quick math: 225/50 R17 is 25.4 mm taller than 225/50 R16, shifting the speedometer by +4.02%.

Speedometer impact
At a true 100 km/h, your dashboard will read 104.0 km/h after switching to 225/50 R17 — a +4.02% 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 +12.7 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.
