What 285/75R17 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 285/75R17 from the factory in our 2017-2026 fitment data — it is an upgrade size, filed in our candidate set as aggressive: taller than a typical 285/70R17 and more likely to need trimming.
No generation on 17-inch wheels clears 285/75R17 at stock height in our model — it needs more than any tier our matrix models on a 2nd gen Tacoma; a 4-6 in lift on a 3rd gen Tacoma; a leveling kit (1-2 in) on a 4th gen Tacoma.
285/75R17 measures 33.8 in tall and 11.2 in wide, with 8.4 in of sidewall on a 17-inch wheel and about 596 revolutions per mile.
Our per-size candidate table asks for 2-3 in lift with trim as needed before fitting 285/75R17; 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 285/75R17. 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 285/75R17 as aggressive: taller than a typical 285/70R17 and more likely to need trimming.
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 285/75R17 is 2.2 in taller and 0.8 in wider — the gap the fit tiers below are really about.
Will 285/75R17 fit a Tacoma?
285/75R17 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 285/75R17 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.

Our fitment matrix does not model a 2nd gen Tacoma that clears 285/75R17. Even at 3 in suspension lift it tops out at 285/75R16 (33s, about 32.8 in), and 285/75R17 stands 33.8 in — 1.0 in taller than that tier's ceiling. Read it as out of range for this generation rather than a build with a longer parts list.
The candidate table is the looser of the two for 285/75R17: it clears the size at 2-3 in lift with trim as needed, 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 "Taller than a typical 285/70R17 and more likely to need trimming." — 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 285/75R17 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.
285/75R17 at 33.8 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 4-6 in lift. At that tier the matrix models 35x12.50R17 (35s, about 35.0 in), and the clearance work it lists is cab mount chop / relocation, pinch weld, high fender-liner trim, and firewall and front-bumper trimming, with gearing flagged at 4.88-5.29.
Both sources land in the same place for 285/75R17 on a 3rd gen Tacoma: the candidate table files it as aggressive at 3+ in lift with trim as needed — the rule-set's own description of the size reads "Taller than a typical 285/70R17 and more likely to need trimming." — and the matrix agrees at 4-6 in lift. The matrix note at that tier reads: Budget for a spare-tire relocation and speedometer recalibration.
285/75R17 at 33.8 in is past the modeled stock-height ceiling for a 4th gen Tacoma (285/70R17 (33s, about 32.7 in)), so the conservative read this page publishes is a leveling kit (1-2 in). At that tier the matrix models 285/75R17 (skinny 34s, about 34.0 in), and the clearance work it lists is crash-plate removal (2 bolts, reversible) and light fender-liner trim at full lock, with gearing flagged at 4.88 if sluggish.
Both sources land in the same place for 285/75R17 on a 4th gen Tacoma: the candidate table files it as aggressive at Level / 1-2 in with trim as needed — the rule-set's own description of the size reads "Taller than a typical 285/70R17 and more likely to need trimming." — and the matrix agrees at leveling kit (1-2 in). The matrix note at that tier reads: Crash-plate removal replaces the permanent 3rd-gen cab mount chop.
Every tier above is modeled output of our own fitment rule-set applied to 285/75R17, not an install anyone here measured: wheel offset, alignment, mud flaps, and the tire model's real moulded width all move where 285/75R17 starts rubbing. Where the two sources behind those tiers disagree, the number you see is the conservative one.
285/75R17 vs the nearest Tacoma sizes
These are the 4 sizes closest to 285/75R17 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 33x10.5R17 at 33.0 in to 285/75R17 at 33.8 in, and none of them is a factory Tacoma size. Speedometer error is calculated against 285/75R17 at 33.8 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 295/70R17 in place of 285/75R17 puts true speed at 59.0 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 285/75R17. Width moves on its own axis: the widest of them, 33x12.5R17, is 1.3 in wider than 285/75R17, and section width is what reaches the fender liner and the upper control arm first.
Top-ranked 285/75R17 tires for a Tacoma
Our tire research dataset lists 25 models offered in 285/75R17. No Tacoma ships the size, so the shortlist leads with the category our candidate table's aggressive rating points at rather than with a factory fitment. Below are the 3 best-ranked rugged-terrain (hybrid) 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 285/75R17 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.
Not in our fitment model: a 2nd gen Tacoma needs more than any tier our matrix models, a 3rd gen Tacoma needs a 4-6 in lift, and a 4th gen Tacoma needs a leveling kit (1-2 in). Our candidate table and our generation matrix disagree about 285/75R17 on a 2nd 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.
285/75R17 works out to 33.8 in of overall diameter and 11.2 in of section width, with 8.4 in of sidewall over a 17-inch wheel. The math is the standard one: 285 mm of section width at a 75 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 596 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.
285/75R17 is 0.6 in taller and 0.4 in narrower than 295/70R17: 33.8 in against 33.3 in of overall diameter, and 11.2 in against 11.6 in of section width. In revolutions per mile that is 596 against 606, so a speedometer calibrated for 285/75R17 would read 59.0 mph of true speed at an indicated 60 once 295/70R17 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 285/75R17; our candidate set carries it as aggressive instead. That matters for two practical reasons: there is no door-placard pressure figure written for 285/75R17 on a Tacoma, and the speedometer in any truck you fit it to was calibrated for a different diameter than 33.8 in.
