Comparison
205/60 R16 vs 225/55 R17
Going from 205/60 R16 to 225/55 R17 steps up to a 17-inch rim while trimming sidewall to stay near OEM rolling diameter. This wheel and tire pairing noticeably changes overall diameter compared to OEM. The shorter sidewall gives the tire a firmer, more responsive feel and sharpens steering input.
The speedometer error is noticeable and may warrant a recalibration if you rely on indicated speed. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeCommon upgrade for sportier handling and a tighter wheel-gap look on the same vehicle.
Quick math: 225/55 R17 is 26.9 mm taller than 205/60 R16, shifting the speedometer by +4.12%.
