275/45R21
Tire size lookup — every vehicle row in this catalog that lists 275/45R21 (25 references).
Use this page as a reverse index: jump to a make/model page for year-sorted context, or follow a bolt pattern link when you are also matching wheels. Trims and markets vary, so treat each row as a guide and confirm against your installed tires and manufacturer documentation.
From here you can open the tire sizes catalog or the bolt pattern catalog for broader browsing.
FAQ
- What does the 275/45R21 tire marking mean?
- 275/45R21 is a metric tire code: section width in millimeters, aspect ratio (sidewall height as a percent of width), construction (R = radial), and rim diameter in inches. Always match load/speed ratings and verify overall diameter effects on your speedometer.
- Why are several different vehicles listed for one tire size?
- Many OEM applications reuse the same tire marking across makes, model years, and trims. This page groups catalog rows that reference the marking so you can compare wheel references and follow links to model-specific pages.
- Is this official OEM documentation?
- No—treat this dataset as a practical reference compiled from public-style fitment rows. Markets, packages, and factory options differ; verify the exact row for your VIN or tire placard before ordering.
