What 265/70R18 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
265/70R18 is a factory Toyota Tacoma tire size: our fitment data records it on 4 trim rows across 2024-2026 — TRD Off-Road i-FORCE MAX (2026), Trailhunter (2026), TRD Pro (2026), and TRD Off-Road (2024).
At stock height our fitment model clears 265/70R18 on 4th gen Tacoma, and asks for a 3 in suspension lift on a 2nd gen Tacoma and a 3rd gen Tacoma.
265/70R18 measures 32.6 in tall and 10.4 in wide, with 7.3 in of sidewall on an 18-inch wheel and about 619 revolutions per mile.
Our per-size candidate table asks for Factory height with no trimming before fitting 265/70R18; the tiers on this page publish whichever of that and the generation ceiling is stricter.
Our fitment data holds 4 factory rows on 265/70R18, spanning 2024 to 2026, all of them on the 4th gen Tacoma: TRD Off-Road i-FORCE MAX (2026), Trailhunter (2026), TRD Pro (2026), and TRD Off-Road (2024). That is what makes 265/70R18 a replacement question for those trucks rather than an upgrade question.
The wheels under those 265/70R18 rows are 18-in TRD Off-Road alloy, 18-in Trailhunter bronze-finished alloy, and 18-in TRD Pro black alloy, and the tire itself is recorded as all-terrain and rugged-terrain, with Falken WildPeak and Goodyear Territory R/T named on some rows. 1 of the 4 rows is package- or configuration-dependent rather than a plain standard fitment, so two trucks wearing the same badge can leave the factory on different tires.
Will 265/70R18 fit a Tacoma?
265/70R18 is an 18-inch size, so the generations it can go on without new wheels are the ones our size families run on 18-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 265/70R18 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
265/70R18 at 32.6 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 265/70R18: it clears the size at Factory height with no trimming, 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 "Factory 33-inch-class size on the current Trailhunter and TRD Pro." — 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 265/70R18 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.
265/70R18 at 32.6 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 3 in suspension lift. At that tier the matrix models 285/70R17 (33s, about 32.7 in), and the clearance work it lists is fender liner trim / pushback, aftermarket UCAs recommended, and cab mount chop for rub-free off-road, with gearing flagged at 4.56-4.88.
The same disagreement as on the 2nd gen Tacoma applies to 265/70R18 here: the candidate table clears it at Factory height with no trimming, the 3rd gen Tacoma ceiling does not reach that far, and the tier above is the matrix's conservative one.
The 4th gen Tacoma ships 265/70R18 from the factory on TRD Off-Road i-FORCE MAX, Trailhunter, TRD Pro, and TRD Off-Road, so on this generation it is a stock fitment rather than an upgrade. Our matrix puts a stock-height 4th gen Tacoma at 285/70R17 (33s, about 32.7 in), and 265/70R18 at 32.6 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 265/70R18 on a 4th gen Tacoma: the candidate table files it as balanced 33 at Factory height with no trimming — the rule-set's own description of the size reads "Factory 33-inch-class size on the current Trailhunter and TRD Pro." — and the matrix agrees at stock height. The matrix note at that tier reads: The big 4th-gen win: a true 33 (285/70R17) clears at stock height with only the mud flaps off. Taller 33s like 275/70R18 are a leveling-kit size.
Every tier above is modeled output of our own fitment rule-set applied to 265/70R18, not an install anyone here measured: wheel offset, alignment, mud flaps, and the tire model's real moulded width all move where 265/70R18 starts rubbing. Where the two sources behind those tiers disagree, the number you see is the conservative one.
265/70R18 vs the nearest Tacoma sizes
These are the 4 sizes closest to 265/70R18 in overall diameter that also run 18-inch wheels, so every swap in the table is a tire change rather than a wheel change. The set runs from 265/65R18 at 31.6 in to 285/70R18 at 33.7 in, and 265/65R18 is a factory Tacoma size. Speedometer error is calculated against 265/70R18 at 32.6 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 285/70R18 in place of 265/70R18 puts true speed at 62.0 mph when the speedometer still reads 60. 265/65R18 and 285/70R18 sit outside the 3 percent window our speedometer calculator treats as the safe band against 265/70R18, so those are recalibration territory. Width moves on its own axis: the widest of them, 285/70R18, is 0.8 in wider than 265/70R18, and section width is what reaches the fender liner and the upper control arm first.
Top-ranked 265/70R18 tires for a Tacoma
Our tire research dataset lists 39 models offered in 265/70R18 — the size that 4 Tacoma factory rows in our data run, recorded as all-terrain and rugged-terrain fitments. 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 265/70R18 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 3 in suspension lift. Our candidate table and our generation matrix disagree about 265/70R18 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.
265/70R18 works out to 32.6 in of overall diameter and 10.4 in of section width, with 7.3 in of sidewall over an 18-inch wheel. The math is the standard one: 265 mm of section width at a 70 percent aspect ratio gives the sidewall, and overall diameter is the 18-inch rim plus twice that sidewall. At that diameter the tire turns about 619 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.
265/70R18 is 0.6 in shorter and 0.4 in narrower than 275/70R18: 32.6 in against 33.2 in of overall diameter, and 10.4 in against 10.8 in of section width. In revolutions per mile that is 619 against 608, so a speedometer calibrated for 265/70R18 would read 61.0 mph of true speed at an indicated 60 once 275/70R18 was fitted. Both sit on 18-inch wheels, so moving between them is a tire purchase rather than a wheel purchase.
Our fitment data records 265/70R18 on 4 Tacoma trim rows between 2024 and 2026: TRD Off-Road i-FORCE MAX (2026), Trailhunter (2026), TRD Pro (2026), and TRD Off-Road (2024). Every one of those model years is sourced from year-specific documentation in our dataset. Confirm the exact size on the driver's door placard or the tire sidewall before you buy.
