What size tires are on a 2015 Toyota Tundra?
There isn’t a single tire size for the 2015 Toyota Tundra; it depends on trim, cab configuration and wheel choice. The lineup commonly uses 17-, 18-, or 20-inch wheels, with representative OEM sizes including P265/70R17, P275/65R18, and P275/55R20.
This article explains the typical sizes by wheel diameter, how to verify your vehicle’s exact spec, and what to know if you’re replacing tires or upgrading wheels.
Common stock tire sizes by wheel diameter
Before listing the typical sizes, note that trim levels and factory packages determine the exact tire that ships with a Tundra. The sizes below reflect common factory configurations for the 2015 model year.
Trim-level variations that affect tire size
- P265/70R17 — frequently found on base and mid-range 17-inch configurations (SR/SR5 with 17-inch wheels).
- P275/65R18 — common on many 18-inch setups in higher trims or optional packages.
- P275/55R20 — typical for higher-end trims with 20-inch wheels (Limited/Platinum and certain premium packages).
These are representative examples; some models may use similar-but-not-identical sizes depending on options and bed configuration. Always verify the exact spec for your vehicle.
How to verify the exact tire size on your vehicle
The precise OEM size can be confirmed in several ways. The tire sidewall shows the size, for example P265/70R17. The driver’s-side door jamb placard lists the recommended tire size and inflation pressures. The owner’s manual also documents the correct OEM tire size for each trim. If you’re replacing tires and want to match factory performance, use the exact size listed on these sources, or consult a tire professional for alternatives.
Why tire size matters
Tyre sizes affect speedometer accuracy, clearance, ride quality, and overall performance. Going significantly larger or smaller can alter gearing, fuel economy, and safety-system operation. When changing sizes, aim for a similar overall diameter or consult a professional about adjustments to speedometer calibration and vehicle dynamics.
Summary
The 2015 Toyota Tundra offered multiple tire sizes based on trim and wheel choices. Common OEM sizes include P265/70R17, P275/65R18, and P275/55R20, though exact specs vary. Check the door placard or owner's manual to confirm the correct size for your specific vehicle, especially before purchasing replacements or wheels.
