Comparison
215/65 R15 vs 215/65 R16
215/65 R16 is a plus-1 alternative to 215/65 R15 — the bigger wheel shows through a thinner sidewall. This alternative fitment swings rolling diameter far enough to feel on the road. Many drivers pick this direction primarily for appearance — the bigger rim simply looks more aggressive.
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.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.
Quick math: 215/65 R16 is 25.4 mm taller than 215/65 R15, shifting the speedometer by +3.85%.
