A tire size like 225/65R17 packs three key dimensions into one string: 225 mm section width, a 65% aspect ratio (sidewall height relative to width), and a 17-inch rim. Together they set the tire's overall diameter, ride height, and handling character.
Base trims typically ship with smaller wheels and taller sidewalls — better ride comfort and cheaper to replace. Sport or premium trims get bigger wheels and lower-profile tires for sharper handling, but the overall diameter stays roughly the same.
OEM sizes reflect factory fitments; verify against your door-jamb placard.
The easiest place is the door-jamb placard on the driver's side door frame — it lists the OEM tire size, recommended pressure, and load capacity. It's also in your owner's manual and printed on the tire sidewall itself.
225 is the section width in millimetres, 65 is the aspect ratio (sidewall height is 65% of the width), R means radial construction, and 17 is the rim diameter in inches. Together they define the tire's physical dimensions.
You can, within limits. The overall diameter should stay within about 3% of the OEM size to keep your speedometer accurate and avoid rubbing. A wider tire may improve grip but can affect fuel economy and clearance. Always match the load and speed ratings your vehicle requires.
Often not. Base trims usually ship with smaller wheels and taller-sidewall tires, while sport or premium trims get larger wheels with lower-profile tires. The overall diameter is typically kept close, but the ride characteristics differ.
Tire sizes shown are OEM factory fitments compiled from well-documented sources. Always confirm your exact tire size, load rating, and speed rating against the door-jamb placard or owner's manual before buying tires.
