What does 225/60R17 mean?
In 225/60R17, 225 is the nominal section width in millimeters, 60 is the aspect ratio, R means radial construction and 17 is the wheel diameter in inches.
Where should you verify the correct size?
Check the driver-door placard and vehicle owner guidance, then compare the complete designation with the current tire. A similar diameter does not guarantee correct load capacity, speed rating or clearance.
Can you change tire size?
A size change should be evaluated for wheel width, overall diameter, load rating, speed rating, clearance, drivetrain behavior and manufacturer guidance. Confirm the application before purchase.
