Toyota Tacoma OEM tire sizes: the complete dataset

Every Tacoma tire size chart on the internet gives you a table. This one gives you the table and the evidence behind each of its rows, because those are not the same thing and the difference decides whether a size is safe to act on.

The dataset below has two tiers and they are not interchangeable. The first is 48 trim rows covering 2017 through 2026: a trim, a configuration, a factory tire size, a wheel, and the availability wording the source used, graded on a three-point scale and — where the grade allows it — attributed to a named Toyota document. The second is the size families for 1995-2016, which exist here as community-documented generation patterns and nothing more. No Toyota document in our source set assigns sizes to trims for those years, so no row claims one.

We are not aware of another Tacoma size reference that grades anything. That is the whole reason this page exists: a chart that cannot tell you which of its rows are sourced is asking you to trust all of them equally, and 11 of these 48 rows do not deserve that.

48 rows in 6 year groups. Several groups span more than one model year because the sources never separated them at the trim level — 2017-2020 and 2021-2022 each hold one row set shared across their years, which expands to 71 year-level rows across the 10 covered model years.

The availability column is quoted from the source rather than normalised: "likely standard" and "standard" mean different things and the hedge is the honest one where the source hedged. The grade column is the row's own grade, never the group's — a package-dependent fitment inside an otherwise well-sourced year is graded on its own merits.

The table below is the other tier, and it is weaker on purpose. 1st gen Tacoma (1995-2004) and 2nd gen Tacoma (2005-2015) are each a long-running community-documented pattern, not a verified per-year spec — the sizes are widely reported and consistent across owner communities, but this dataset holds no Toyota document that assigns any of them to a trim, and no per-trim row exists for those years at all.

Read the coverage column before you read the sizes. It states, per generation, which model years actually have graded per-trim rows above and which have none.

Treat every 1995-2016 size as a family the generation used somewhere in its run, not as your truck's factory fitment. Confirm the exact size on the driver's door placard or the tire sidewall before you buy.

Three grades, defined by the dataset itself. The definitions below are quoted verbatim from its quality scale — they are the criteria the rows were graded against, not a summary of them written afterwards.

• A grade is not a citationA row may name a Toyota document only when its model year was proven at the trim level. The 2017-2020 and 2025 groups do carry Toyota document references, but those documents were read for "this size exists in this year" rather than "this size belongs to this trim". The exception is 3 rows in the 2025 group, whose notes record a Toyota pressroom statement that does name the trim — but states the tire in inches with no metric size, and the 2026-08-15 retrieval could not re-check it. Naming a document beside any of these rows would publish a provenance that either does not exist or that we could not confirm, so they cite nothing and are framed as the pattern instead.
• The row's grade wins, not the group'sA medium row inside a high group says medium, and in this dataset that is not a hypothetical: 10 of the 37 rows sitting inside groups the dataset stamps "high" are themselves graded lower. Package-dependent fitments and rows where the source gives only a nominal size are marked down individually, which is why 16 of the 48 rows are graded medium. Read the row, not the group.
• A nominal size is never convertedWhere a source states a "33 in" tire on an 18-inch wheel and gives no metric equivalent, this dataset reproduces that wording and publishes no metric size for the row. 5 rows are in that position. A metric size invented to fill the column would be indistinguishable, to a reader, from one Toyota published.
• Verification is dated, and so are its failuresThe dataset was last reviewed against sources on 2026-06-24. A re-verification pass on 2026-08-15 targeted flagged year groups 2017-2020 and 2025 and retrieved 0 of 10 documents, so no row was upgraded and the review date was deliberately left where it was. A freshness date that moves when nothing was verified is worth less than no date.

What the review said about each year group

Each year group also carries the dataset's own internal publish verdict — the note the review left about how far that group may be trusted in public. They are quoted here verbatim, including the unflattering ones.

2026

Best-quality year in this set because Toyota.com current specs expose trim-level tire and wheel rows.

2025

Useful, but not complete enough to headline as an exact trim table unless we backfill 2025 Toyota.com trim rows or a brochure/spec sheet. The 2026-08-15 re-verification pass could not retrieve toyota_2025_manual or toyota_2025_pressroom (both blocked by session egress policy), and no 2025 brochure has been located for this source set, so the trim mapping is still unproven and every row stays 'medium'.

2024

High quality. The feature matrix and wheels page should be read together because the matrix has wheel-diameter wording that conflicts with the tire rim size on two TRD rows.

2023

Good enough for a public trim table. Trail Special Edition has its own exact row.

2021-2022

Good enough for a public trim table. Mark SR and SR5 rows as engine/package dependent.

2017-2020

Use as a legacy pattern table only. A prior review recorded that Toyota owner manuals confirm the available tire sizes, but the source set has never proven the trim mapping. The 2026-08-15 re-verification pass could not retrieve any of the four manuals listed below (all assets.sia.toyota.com URLs blocked by session egress policy), so nothing here was re-checked against a document and every row stays 'low'.

Every document the dataset references, numbered as the tables above reference them. A number beside a year group means that group's trim rows were verified against that document. The 2017-2020 and 2025 groups reference documents that list sizes for those years without assigning them to trims, the one exception being 3 rows whose notes record an unverified Toyota pressroom statement naming the trim in inches — which is why none of their rows carries a reference number.
