Comparison
185/70 R14 vs 195/50 R16
Switching from 185/70 R14 to 195/50 R16 is a plus-2 upgrade that wraps a shorter sidewall around a larger 16-inch wheel. This setup trims or stretches rolling diameter by a small margin.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. The shorter sidewall gives the tire a firmer, more responsive feel and sharpens steering input. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. The larger wheel shows more of the brake hardware and tightens up the wheel-gap look. Diameter change stays inside the conservative ±3% safety window — an OEM-safe fitment on most vehicles.
TakeCommon upgrade for sportier handling and a tighter wheel-gap look on the same vehicle.
Quick math: 195/50 R16 is 13.2 mm shorter than 185/70 R14, shifting the speedometer by -2.15%.

Speedometer impact
At a true 100 km/h, your dashboard will read 97.9 km/h after switching to 195/50 R16 — a -2.15% 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 -6.6 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.
