What 275/70R17 measures, which Tacoma trims ship it from the factory, and what our fitment model says it takes to run it by generation.
Will it fit
No Tacoma ships 275/70R17 from the factory in our 2017-2026 fitment data — it is an upgrade size, filed in our candidate set as mild upgrade: adds a little height and width without jumping straight to 285s.
At stock height our fitment model clears 275/70R17 on 4th gen Tacoma (with minor changes, so not a pure bolt-on), and asks for a 3 in suspension lift on a 2nd gen Tacoma; a leveling kit (1-2 in) on a 3rd gen Tacoma.
275/70R17 measures 32.2 in tall and 10.8 in wide, with 7.6 in of sidewall on a 17-inch wheel and about 627 revolutions per mile.
Our per-size candidate table asks for Factory height with minor changes before fitting 275/70R17; the tiers on this page publish whichever of that and the generation ceiling is stricter.
No Tacoma in our 2017-2026 fitment data leaves the factory on 275/70R17. It reaches Tacomas as an aftermarket choice, which is why this page leads with what it takes to fit rather than with which trim wears it. Our candidate set files 275/70R17 as mild upgrade: adds a little height and width without jumping straight to 285s.
The nearest factory size on the same 17-inch wheel is 265/70R17 at 31.6 in, which our data records on 5 Tacoma rows (TRD PreRunner (2024-2026), TRD Off-Road (2024-2026), and TRD PreRunner / TRD Off-Road gas (2025)). Against it 275/70R17 is 0.6 in taller and 0.4 in wider — the gap the fit tiers below are really about.
Will 275/70R17 fit a Tacoma?
275/70R17 is a 17-inch size, so the generations it can go on without new wheels are the ones our size families run on 17-inch rims: 2nd gen Tacoma (2005-2015), 3rd gen Tacoma (2016-2023), and 4th gen Tacoma (2024-2026). Two sources in this repo have an opinion about 275/70R17 on each of them — the per-generation clearance matrix behind our max-tire estimator, and the per-size candidate table behind the recommender — and where they disagree, the stricter of the two is what you read below.

Inside the ceiling · published tier
275/70R17 at 32.2 in is past the modeled stock-height ceiling for a 2nd gen Tacoma (265/70R16 (~30.6 in)), so the conservative read this page publishes is a 3 in suspension lift. At that tier the matrix models 285/75R16 (33s, about 32.8 in), and the clearance work it lists is fender liner trim and cab mount chop for full articulation, with gearing flagged at 4.56-4.88.
The candidate table is the looser of the two for 275/70R17: it clears the size at Factory height with minor changes, which the 2nd gen Tacoma ceiling above does not support. That table rates a size on its own terms — the rule-set's own generation-agnostic description of the size reads "Adds a little height and width without jumping straight to 285s." — with no generation column to narrow it, so where the two disagree this page publishes the matrix tier.
One sourcing caveat for the 2nd gen Tacoma: our per-year fitment rows start at 2017, so nothing in this repo assigns 275/70R17 to a 2005-2015 trim. The 17-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.
275/70R17 at 32.2 in is past the modeled stock-height ceiling for a 3rd gen Tacoma (265/70R17 (~31.6 in)), so the conservative read this page publishes is a leveling kit (1-2 in). At that tier the matrix models 275/70R17 (~32.2 in), and the clearance work it lists is remove mud flaps.
The same disagreement as on the 2nd gen Tacoma applies to 275/70R17 here: the candidate table clears it at Factory height with minor changes, the 3rd gen Tacoma ceiling does not reach that far, and the tier above is the matrix's conservative one.
On a 4th gen Tacoma our matrix models stock height at 285/70R17 (33s, about 32.7 in). 275/70R17 measures 32.2 in, 0.5 in shorter than that ceiling, so the modeled read is that it clears with no suspension work — though the candidate table still asks for minor changes, so it is not a pure bolt-on.
Both sources land in the same place for 275/70R17 on a 4th gen Tacoma: the candidate table files it as mild upgrade at Factory height with minor changes — the rule-set's own description of the size reads "Adds a little height and width without jumping straight to 285s." — 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 275/70R17.
Every tier above is modeled output of our own fitment rule-set applied to 275/70R17, not an install anyone here measured: wheel offset, alignment, mud flaps, and the tire model's real moulded width all move where 275/70R17 starts rubbing. Where the two sources behind those tiers disagree, the number you see is the conservative one.
275/70R17 vs the nearest Tacoma sizes
These are the 4 sizes closest to 275/70R17 in overall diameter that also run 17-inch wheels, so every swap in the table is a tire change rather than a wheel change. The set runs from 265/70R17 at 31.6 in to 33x12.5R17 at 33.0 in, and 265/70R17 is a factory Tacoma size. Speedometer error is calculated against 275/70R17 at 32.2 in — the size the truck would be calibrated for if it wore this page's tire.
That last column is the error you would carry after the swap, before any recalibration: fitting 33x10.5R17 in place of 275/70R17 puts true speed at 61.6 mph when the speedometer still reads 60. Every alternative here stays inside the 3 percent window our speedometer calculator treats as the safe band against 275/70R17. Width moves on its own axis: the widest of them, 33x12.5R17, is 1.7 in wider than 275/70R17, and section width is what reaches the fender liner and the upper control arm first.
Top-ranked 275/70R17 tires for a Tacoma
Our tire research dataset lists 32 models offered in 275/70R17. No Tacoma ships the size, so the shortlist leads with the category our candidate table's mild upgrade rating points at rather than with a factory fitment. Below are the 3 best-ranked mild all-terrain models offered in it, plus the all-terrain BFGoodrich All-Terrain T/A KO3 for contrast — built for a different job, so it scores on different axes.
Scores are a 0-10 editorial synthesis of published reviews, manufacturer specifications, and retailer fitment data — not tires we tested ourselves. Which models are offered in 275/70R17 is the research dataset's own size catalog, which is why a thinly-catalogued size returns a short list here rather than a padded one. The order above is that dataset's editorial rank; the 0-10 badge is the blended score behind it, so a higher badge on a lower-ranked model is the two measures disagreeing rather than a mistake. How we source and score.
It depends which Tacoma. In our fitment model a 4th gen Tacoma clears it at stock height (modeled ceiling 32.7 in), while a 2nd gen Tacoma needs a 3 in suspension lift and a 3rd gen Tacoma needs a leveling kit (1-2 in). Stock height is not the same as bolt-on here: our per-size rules rate 275/70R17 for minor changes whatever the suspension is doing. Our candidate table and our generation matrix disagree about 275/70R17 on a 2nd gen Tacoma and a 3rd gen Tacoma, and the answer above is the conservative side of that disagreement. Both are modeled estimates rather than installs we measured, and lower-offset wheels or spacers can undo any of them.
275/70R17 works out to 32.2 in of overall diameter and 10.8 in of section width, with 7.6 in of sidewall over a 17-inch wheel. The math is the standard one: 275 mm of section width at a 70 percent aspect ratio gives the sidewall, and overall diameter is the 17-inch rim plus twice that sidewall. At that diameter the tire turns about 627 revolutions per mile, and a mounted tire can measure a little off these numbers depending on the model and the rim width it is fitted to.
275/70R17 is 0.6 in taller and 0.4 in wider than 265/70R17: 32.2 in against 31.6 in of overall diameter, and 10.8 in against 10.4 in of section width. In revolutions per mile that is 627 against 638, so a speedometer calibrated for 275/70R17 would read 59.0 mph of true speed at an indicated 60 once 265/70R17 was fitted. Both sit on 17-inch wheels, so moving between them is a tire purchase rather than a wheel purchase.
No. Across the 2017-2026 model years our fitment data covers, no Tacoma trim row leaves the factory on 275/70R17; our candidate set carries it as mild upgrade instead. That matters for two practical reasons: there is no door-placard pressure figure written for 275/70R17 on a Tacoma, and the speedometer in any truck you fit it to was calibrated for a different diameter than 32.2 in.
