Practical Guidance

A 9.0% diameter difference is significantly outside the safe replacement range. Switching from 215/60R16 to 225/65R17 can cause dangerous speedometer inaccuracy, ABS/traction control malfunctions, and potential clearance issues. This change is not recommended without professional verification and possible ECU recalibration.

The 3% diameter tolerance is a widely accepted industry guideline referenced by the ETRTO and most vehicle manufacturers. When in doubt, consult your vehicle's owner's manual or a qualified tire professional. For U.S. tire safety standards and recalls, see the NHTSA Tire Safety page.
