Comparison
215/65 R16 vs 225/55 R16
Going from 215/65 R16 to 225/55 R16 keeps the rim but tightens the sidewall for a sportier look. This wheel and tire pairing 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. Expect a more planted steering feel, at the cost of some of the cushioning a taller sidewall provides. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
