What this swap means for your car

When you go from 195/65 R15 to 195/60 R15, the sidewall height changes from 126.8 mm to 117.0 mm. The shorter sidewall gives sharper turn-in and a firmer ride, with a bit more road noise.

The rim grows 195/65 R15″ → 195/60 R15″. The total diameter changes by -3.07%, which means the car sits slightly lower and the speedometer over-reads.
