What this swap means for your car

When you go from 195/60 R15 to 195/55 R16, the sidewall height changes from 117.0 mm to 107.3 mm. The shorter sidewall gives sharper turn-in and a firmer ride, with a bit more road noise.

The rim grows 195/60 R15″ → 195/55 R16″. The total diameter changes by +0.96%, which means the car sits slightly higher and the speedometer under-reads (you travel faster than the needle shows).

FAQ

The total diameter difference is only 0.96%, which is within the safe ±3% window. Always still confirm brake and body clearance, plus the load and speed indexes.
With the 195/55 R16 mounted instead of the 195/60 R15, the speedometer under-reads (you go faster than shown). At a real 100 km/h the needle shows about 101 km/h.
Yes — the lower aspect ratio (shorter sidewall) gives sharper handling but a firmer ride and more road noise.
No alignment is required just for changing tire size, but check the tires are balanced and the pressures are correct.
