Comparison
215/60 R17 vs 225/65 R17
On the same 17-inch wheel, 225/65 R17 grows the section width by 10 mm versus 215/60 R17. This tire combination moves rolling diameter well outside the usual OEM tolerance. The taller sidewall adds cushioning over potholes and rougher roads, with a softer overall ride.
Speedometer error is large enough that recalibration is effectively required for accurate readings. A diameter change beyond 5% is aggressive enough to influence ABS, traction control and gearing; treat it as a serious modification.
TakeTreat as a serious modification — verify clearance, recalibrate the speedometer and reassess load capacity.
Quick math: 225/65 R17 is 34.5 mm taller than 215/60 R17, shifting the speedometer by +5.00%.

Over 5% diameter difference — likely to affect speedometer accuracy, ABS calibration and gearing. Not recommended without professional review.
Speedometer impact
At a true 100 km/h, your dashboard will read 105.0 km/h after switching to 225/65 R17 — a +5.00% offset. Use the speedometer error calculator to recheck for other indicated speeds, and the speedometer error guide for the full background.
Ground clearance change
The new tire's half-diameter changes ride height by +17.3 mm. Small differences are absorbed by suspension travel, but anything beyond ±10 mm can affect headlight aim, fender clearance and bump-stop margin. See the plus-sizing guide before committing.
