What changes between 215/60R16 and 225/60R16
Switching from 215/60R16 to 225/60R16 changes overall diameter by +1.81%, a taller tire by 0.47 inches. This lands inside the ±3% fitment safe zone, so most vehicles will accept the swap without rubbing, speedometer recalibration, or ABS/TPMS complications. Section width moves by +0.40″ (215mm → 225mm), which affects contact patch and fender-well clearance. Sidewall height shifts by +0.23″: a taller sidewall softens ride quality and adds off-road bump protection, with some loss of steering crispness. Revs per mile moves by -14, which translates directly to speedometer error — at an indicated 65 mph, actual speed becomes 66.2 mph. Both sizes share the same 16″ rim, so no wheel change is required — this is a pure tire-only swap.
