Comparison
195/60 R16 vs 245/45 R17
245/45 R17 is a plus-1 alternative to 195/60 R16 — the bigger wheel shows through a thinner sidewall. This sizing approach shifts overall diameter slightly from OEM. 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. 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: 245/45 R17 is 11.9 mm taller than 195/60 R16, shifting the speedometer by +1.86%.

Speedometer impact
At a true 100 km/h, your dashboard will read 101.9 km/h after switching to 245/45 R17 — a +1.86% 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 +5.9 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.
