Comparison
195/60 R16 vs 245/35 R18
Plus-sizing from 195/60 R16 to 245/35 R18 keeps overall diameter close to factory while opening room for a larger 18-inch wheel. This sizing approach moves rolling diameter a touch off the original spec. Expect a more planted steering feel, at the cost of some of the cushioning a taller sidewall provides.
Expect a slight but noticeable shift in indicated speed compared to the original tires. 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: 245/35 R18 is 11.7 mm shorter than 195/60 R16, shifting the speedometer by -1.83%.

Speedometer impact
At a true 100 km/h, your dashboard will read 98.2 km/h after switching to 245/35 R18 — a -1.83% 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 -5.8 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.
