Comparison
235/60 R16 vs 235/65 R16
235/65 R16 is a taller-sidewall alternative to 235/60 R16 on the same 16-inch rim. This swap moves rolling diameter well outside the usual OEM tolerance.
Indicated speed will drift far enough that recalibration is worth considering. Extra sidewall absorbs impacts more readily — a sensible bias for daily commuting and broken pavement. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeA comfort-leaning direction that's easier on wheels and suspension over rough surfaces.
Quick math: 235/65 R16 is 23.5 mm taller than 235/60 R16, shifting the speedometer by +3.41%.
