Comparison
215/65 R16 vs 235/65 R16
Stepping from 215/65 R16 to 235/65 R16 keeps the 16-inch wheel but widens the section by 20 mm. This swap moves rolling diameter well outside the usual OEM tolerance. The speedometer error is noticeable and may warrant a recalibration if you rely on indicated speed. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakeUseful when extra dry grip and stance matter more than a small fuel-economy hit.
Quick math: 235/65 R16 is 26.0 mm taller than 215/65 R16, shifting the speedometer by +3.79%.
