Comparison
225/50 R18 vs 265/35 R19
Switching from 225/50 R18 to 265/35 R19 is a plus-1 upgrade that wraps a shorter sidewall around a larger 19-inch wheel. This sizing approach trims or stretches rolling diameter by a small margin. The shorter sidewall gives the tire a firmer, more responsive feel and sharpens steering input.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.
Quick math: 265/35 R19 is 14.1 mm shorter than 225/50 R18, shifting the speedometer by -2.07%.

Speedometer impact
At a true 100 km/h, your dashboard will read 97.9 km/h after switching to 265/35 R19 — a -2.07% 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 -7.1 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.
