Compare this sizeHow does the Tacoma OEM tire size lookup work?
The lookup turns a Toyota Tacoma model year and trim into the tire size, wheel, and tire type the truck left the factory on. That stock size is the starting point for any upgrade on this midsize pickup, so the lookup feeds straight into the tire size calculator.
What do I enter?
- Model year, 2017-2026, including the 2024-2026 4th gen.
- Trim level for that year (SR, SR5, TRD Sport, TRD Off-Road, TRD Pro, and so on).
What does it show?
- The factory tire size for each configuration of that trim, with its overall diameter.
- Factory wheel size and type, and the tire type the truck shipped on.
- Whether a size is standard or package-dependent, and package alternatives where a trim offers more than one.
- The Toyota document behind the year, or a plain note when the year follows the generation's factory pattern.
What does the lookup return for a 2026 SR5?
Pick 2026 and SR5 and the lookup returns 245/70R17 (about 30.5 in tall) on 17-in styled alloy wheels, listed as standard. That size is the baseline to enter as "current" in the tire calculator before comparing an upgrade.

How is it different from a generic tire size lookup?
- Year- and trim-specific Tacoma data instead of a generic make-and-model menu, through the current 4th gen.
- Sourced, with the limits stated: years read from a Toyota document cite it, and the rest say they follow the generation pattern. The door-jamb placard always outranks the table.
- Linked to the next step: every stock size feeds the tire calculator and the Tacoma size pages, so you can go straight from your factory baseline to a comparison and a clearance check.
Where do these sizes come from?
Model years read from a year-specific Toyota document cite that document below. The rest follow the common factory pattern for the generation, and say so instead of naming a document they were never proven against. On any year, the door-jamb placard outranks this table.
| Model years | Configurations | Source |
|---|---|---|
| 20264th gen Tacoma | 11 | |
| 20254th gen Tacoma | 6 | Sizes for 2025 follow the common factory pattern for the 4th gen Tacoma — confirm yours on the door placard or the tire sidewall. Toyota pressroom statements named three of them in inches, with no metric size. |
| 20244th gen Tacoma | 10 | |
| 20233rd gen Tacoma | 8 | |
| 2021–20223rd gen Tacoma | 8 | |
| 2017–20203rd gen Tacoma | 5 | Sizes for 2017–2020 follow the common factory pattern for the 3rd gen Tacoma — confirm yours on the door placard or the tire sidewall. |
The dataset was last reviewed on 2026-06-24. The 5 model years still published as a pattern (2017, 2018, 2019, 2020, and 2025) are the ones whose trim mapping we have never been able to prove against a document, and we would rather say that than round it up. How we read and rate the sources is on our sourcing page, and every individual listing is published in the OEM tire size dataset study with the document and the verbatim dataset note where those exist.

No. It shows the likely factory tire size from year and trim data. Actual trucks can vary by wheel package, production configuration, dealer-installed parts, or previous owner changes, so confirm against the door placard and the tire sidewall before buying.

Use the tire calculator to compare the OEM size against replacement or upgrade sizes, then confirm load rating, actual tire dimensions, wheel offset, and physical clearance before ordering tires.
Read the tire and loading information placard on the driver's door jamb, which lists the size and cold pressure the truck was built with. The sidewall of the tires on the truck shows what is fitted now. If the two disagree, a previous owner changed sizes, and the placard is the baseline for speedometer and gearing comparisons.
