Comparison
195/55 R15 vs 195/60 R15
Switching from 195/55 R15 to 195/60 R15 keeps the wheel but adds sidewall for extra cushioning. This tire combination noticeably changes overall diameter compared to OEM.
Indicated speed will drift far enough that recalibration is worth considering. More sidewall typically improves comfort and curb protection, especially on city streets. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakeA comfort-leaning direction that's easier on wheels and suspension over rough surfaces.
Quick math: 195/60 R15 is 19.5 mm taller than 195/55 R15, shifting the speedometer by +3.27%.
