Comparison
215/60 R17 vs 245/40 R19
Plus-sizing from 215/60 R17 to 245/40 R19 keeps overall diameter close to factory while opening room for a larger 19-inch wheel. This setup moves rolling diameter a touch off the original spec.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. Expect a more planted steering feel, at the cost of some of the cushioning a taller sidewall provides. 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. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakeCommon upgrade for sportier handling and a tighter wheel-gap look on the same vehicle.
Quick math: 245/40 R19 is 11.2 mm shorter than 215/60 R17, shifting the speedometer by -1.62%.

Speedometer impact
At a true 100 km/h, your dashboard will read 98.4 km/h after switching to 245/40 R19 — a -1.62% 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 -5.6 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.
