Comparison
215/55 R16 vs 225/55 R16
Stepping from 215/55 R16 to 225/55 R16 keeps the 16-inch wheel but widens the section by 10 mm. This alternative fitment shifts overall diameter slightly from OEM.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting. Diameter change stays inside the conservative ±3% safety window — an OEM-safe fitment on most vehicles.
TakeReasonable performance-leaning swap as long as fender and suspension clearance check out.
Quick math: 225/55 R16 is 11.0 mm taller than 215/55 R16, shifting the speedometer by +1.71%.
