Comparison
215/60 R16 vs 235/60 R16
Stepping from 215/60 R16 to 235/60 R16 keeps the 16-inch wheel but widens the section by 20 mm. This swap swings rolling diameter far enough to feel on the road.
Indicated speed will drift far enough that recalibration is worth considering. The wider section adds contact patch and lateral stability, while eating into fender and suspension clearance. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakeReasonable performance-leaning swap as long as fender and suspension clearance check out.
Quick math: 235/60 R16 is 24.0 mm taller than 215/60 R16, shifting the speedometer by +3.61%.
