Comparison
215/50 R17 vs 225/40 R19
Going from 215/50 R17 to 225/40 R19 steps up to a 19-inch rim while trimming sidewall to stay near OEM rolling diameter. This alternative fitment moves rolling diameter a touch off the original spec. Less sidewall flex usually translates to crisper turn-in and a slightly stiffer ride over rough pavement.
Expect a slight but noticeable shift in indicated speed compared to the original tires. 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.
Quick math: 225/40 R19 is 15.8 mm taller than 215/50 R17, shifting the speedometer by +2.44%.

At a true 100 km/h, your dashboard will read 102.4 km/h after switching to 225/40 R19 — a +2.44% 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 +7.9 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.
