265/60R18 on a Toyota Tacoma.

On a 2nd gen Tacoma our matrix models stock height at 265/70R16 (~30.6 in). 265/60R18 measures 30.5 in, 0.1 in shorter than that ceiling, so the modeled read is that it clears with no suspension work and no trimming.

Both sources land in the same place for 265/60R18 on a 2nd gen Tacoma: the candidate table files it as factory-style at Factory height with no trimming — the rule-set's own generation-agnostic description of the size reads "Older Limited-style 18-inch factory-class size." — and the matrix agrees at stock height. The matrix note at that tier reads: Stock-class sizes only without trimming.

One sourcing caveat for the 2nd gen Tacoma: our per-year fitment rows start at 2017, so nothing in this repo assigns 265/60R18 to a 2005-2015 trim. The 18-inch family we list for that span is a long-running community-documented pattern, not a verified per-year spec, and the ceilings above are the estimator's rule-set for the generation rather than measurements from a 2005-2015 truck.

The 3rd gen Tacoma ships 265/60R18 from the factory on Limited and Limited Nightshade package, so on this generation it is a stock fitment rather than an upgrade. Our matrix puts a stock-height 3rd gen Tacoma at 265/70R17 (~31.6 in), and 265/60R18 at 30.5 in sits inside that ceiling — which is the agreement you would expect from a size Toyota fitted itself.

Both sources land in the same place for 265/60R18 on a 3rd gen Tacoma: the candidate table files it as factory-style at Factory height with no trimming — the rule-set's own description of the size reads "Older Limited-style 18-inch factory-class size." — and the matrix agrees at stock height. The matrix note at that tier reads: 265/75R16 is the no-rub 'holy grail' on 16s. True 33s do not fit stock.

On a 4th gen Tacoma our matrix models stock height at 285/70R17 (33s, about 32.7 in). 265/60R18 measures 30.5 in, 2.2 in shorter than that ceiling, so the modeled read is that it clears with no suspension work and no trimming.

Both sources land in the same place for 265/60R18 on a 4th gen Tacoma: the candidate table files it as factory-style at Factory height with no trimming — the rule-set's own description of the size reads "Older Limited-style 18-inch factory-class size." — and the matrix agrees at stock height.

Our two fitment sources disagree about one more thing on the 4th gen Tacoma. The matrix carries a note at that tier — "The big 4th-gen win: 33s (285/70R17 or 275/70R18) fit stock, no trimming." — and our per-size rules overrule it: 285/70R17 sits behind a leveling kit (1-2 in) with minor changes and 275/70R18 sits behind a leveling kit (1-2 in) with minor changes. This page publishes the conservative reading, so treat that note as the matrix's roomiest case rather than a settled bolt-on fit for 265/60R18.
