# 2nd Gen Tacoma Tire Sizes (2005-2015)

Tire sizes for the 2005-2015 second-generation Toyota Tacoma: the documented factory size family, computed dimensions for each size, and how big a tire the fitment model puts on stock, leveled, and lifted trucks.

## Short Answer
The 2005-2015 Tacoma's sizes are a long-running community-documented pattern, not a verified per-year spec in our data: 215/70R15, 245/75R16, 265/70R16, 265/65R17, 265/60R18, and 255/45R18. 4 of them land within 0.14 in of each other around 30.5 in. Our model puts the stock ceiling at 30.6 in, 31.6 in on a level, and 33s at a 3-inch lift.

## What tire sizes did the 2nd gen Tacoma come with?
The second generation covers 2005-2015 — eleven model years, and every one of them falls before our OEM fitment dataset begins in 2017. This page can therefore tell you which sizes belong to the generation, but not which trim or which year each one came on, because nothing in the repo records that mapping.

That distinction is worth being blunt about, because plenty of pages elsewhere are not. A 2005 base model and a 2014 off-road trim are nine model years and several packages apart, and the family below covers both without separating them. If you need the answer for one specific truck, the door placard is the source; this page is for understanding the range and planning a change.

> **No 2nd-gen model year is in our fitment dataset:** The OEM fitment data behind this site covers 2017-2026 only, so all 11 2005-2015 model years fall outside it. The sizes on this page are a long-running community-documented pattern, not a verified per-year spec. No trim, cab, drivetrain, or model year is claimed for any of them, and nothing here reflects a Toyota document we have read. Confirm your own size on the driver's door placard or the tire sidewall.

| Size | Wheel | Overall diameter | Sizing format |
| --- | --- | --- | --- |
| 215/70R15 | 15 in | 26.9 in | Metric — height calculated |
| 255/45R18 | 18 in | 27.0 in | Metric — height calculated |
| 245/75R16 | 16 in | 30.5 in | Metric — height calculated |
| 265/60R18 | 18 in | 30.5 in | Metric — height calculated |
| 265/65R17 | 17 in | 30.6 in | Metric — height calculated |
| 265/70R16 | 16 in | 30.6 in | Metric — height calculated |

*The 2005-2015 size family exactly as our data records it, ordered by computed height. The family itself is a long-running community-documented pattern, not a verified per-year spec; the wheel, height, and format columns are calculated from each size string.*

## How big are the 2nd-gen factory sizes in inches?
Run the 6 second-gen sizes through the size parser and the family splits cleanly in two. 4 of them — 245/75R16, 265/70R16, 265/65R17, and 265/60R18 — land between 30.5 in and 30.6 in, a spread of only 0.14 in across three different wheel diameters. The other 2 sit far below: 215/70R15 at 26.9 in and 255/45R18 at 27.0 in.

| Size | Wheel | Overall diameter | Section width | Sidewall | Revs per mile |
| --- | --- | --- | --- | --- | --- |
| 215/70R15 | 15 in | 26.9 in | 8.5 in | 5.9 in | 751 |
| 245/75R16 | 16 in | 30.5 in | 9.6 in | 7.2 in | 662 |
| 265/70R16 | 16 in | 30.6 in | 10.4 in | 7.3 in | 659 |
| 265/65R17 | 17 in | 30.6 in | 10.4 in | 6.8 in | 660 |
| 265/60R18 | 18 in | 30.5 in | 10.4 in | 6.3 in | 661 |
| 255/45R18 | 18 in | 27.0 in | 10.0 in | 4.5 in | 746 |

*Computed geometry for the 2005-2015 size family. Every figure is calculated from the size string itself; the family it is calculated from is a long-running community-documented pattern, not a verified per-year spec, so no year, trim, or wheel package is claimed for any row.*

The tight cluster is the interesting half. 245/75R16 on a 16-inch wheel, 265/70R16 on a 16-inch wheel, 265/65R17 on a 17-inch wheel, and 265/60R18 on a 18-inch wheel all arrive at essentially the same rolling height by trading sidewall for rim: sidewall falls from 7.3 in on the 16-inch entry to 6.3 in on the 18-inch one, and the wheel grows by just enough to cancel it out. Revolutions per mile barely move — 662 down to 659 — which is why swapping between them leaves the speedometer alone.

The two short entries are a different animal. At 27.0 in and below they sit roughly 3.4 in shorter than the truck cluster, and one of them pairs a 4.5 in sidewall with an 18-inch wheel. Fitting one in place of a cluster size would shorten the truck by more than three inches of rolling diameter and throw the speedometer out badly in the other direction.

## What is the max tire size on a 2nd gen Tacoma?
The second-gen entry in our fitment matrix starts tight and stays modest. It defines 3 tiers and, like the first gen, has no 4-6 inch tier at all. Its top modeled size, 285/75R16 at about 32.8 in, is a 33 by name rather than by measured height — the matrix is explicit that the number on the box and the number on the tape do not match here.

| Suspension | Modeled max size | Commonly called | Diameter | Clearance work the model expects | Regear |
| --- | --- | --- | --- | --- | --- |
| Stock height | 265/70R16 | ~30.6 in | 30.6 in | None | Not called for |
| Leveling kit (1-2 in) | 265/75R16 | ~31.6 in | 31.6 in | Remove mud flaps | Not called for |
| 3 in suspension lift | 285/75R16 | 33s | 32.8 in | Fender liner trim; Cab mount chop for full articulation | 4.56-4.88 |

*Modeled ceilings for the 2nd gen Tacoma on stock-style offset, from the rule-set behind our max tire size estimator. These are estimates read out of a reviewed fitment matrix, not tires anyone here fitted or measured — confirm at full lock and full compression before buying. Diameters are calculated from the size itself; where the matrix's own rounded ceiling differs it is shown beside it.*

Leveling versus lifting, side by side. On the 2nd gen Tacoma's independent front suspension a spacer buys fender gap at ride height and trades away down-travel, while a lift replaces springs and shocks at both ends and can restore the travel it uses. Schematic, not to scale, and no lift height is implied.

- Stock-class sizes only without trimming.
- 285/75R16 possible with liner trim on a level.
- 0 to negative offset helps clear the UCAs.

Notice how little the leveling tier buys on this generation. The model moves the ceiling from 30.6 in to 31.6 in — one inch — and asks only that the mud flaps come off. The jump to the 3-inch tier is where the real work starts: the matrix names a cab mount chop for full articulation at that point, which is permanent metal work rather than a bolt-on part.

> **Every ceiling above assumes stock-style offset:** Offset moves these numbers before anything else does. Ask the estimator for the same 2nd-gen tier with an aggressive offset and it adds one line to the verdict: Negative offset / spacers add outer poke — expect more fender, liner, and full-lock rub.

## Which upgrade sizes fit a 2nd gen Tacoma?
Of the 21 upgrade sizes on our size pages that fit a second-gen wheel diameter, 13 land somewhere on this generation's modeled ladder and 8 sit past its top tier entirely. That 8-size overhang is the clearest single measure of how much tighter this generation is than a current truck.

| Size | Overall diameter | Section width | vs 265/70R16 | Fits from (modeled) | Intent | Minimum clearance work |
| --- | --- | --- | --- | --- | --- | --- |
| 245/75R16 | 30.5 in | 9.6 in | -0.1 in | Stock height | Factory-style | No trimming |
| 265/70R16 | 30.6 in | 10.4 in | 0.0 in | Stock height | Factory-style | No trimming |
| 265/75R16 | 31.6 in | 10.4 in | +1.0 in | Leveling kit (1-2 in) | Mild upgrade | No trimming |
| 285/75R16 | 32.8 in | 11.2 in | +2.2 in | 3 in suspension lift | Balanced 33 | Minor changes |
| 245/70R17 | 30.5 in | 9.6 in | -0.1 in | Stock height | Factory-style | No trimming |
| 265/65R17 | 30.6 in | 10.4 in | -0.0 in | Stock height | Factory-style | No trimming |
| 265/70R17 | 31.6 in | 10.4 in | +1.0 in | Leveling kit (1-2 in) | Mild upgrade | No trimming |
| 275/70R17 | 32.2 in | 10.8 in | +1.6 in | 3 in suspension lift | Mild upgrade | Minor changes |
| 285/70R17 | 32.7 in | 11.2 in | +2.1 in | 3 in suspension lift | Balanced 33 | Minor changes |
| 265/60R18 | 30.5 in | 10.4 in | -0.1 in | Stock height | Factory-style | No trimming |
| 265/65R18 | 31.6 in | 10.4 in | +1.0 in | Leveling kit (1-2 in) | Factory-style | No trimming |
| 285/65R18 | 32.6 in | 11.2 in | +2.0 in | 3 in suspension lift | Balanced 33 | Minor changes |
| 265/70R18 | 32.6 in | 10.4 in | +2.0 in | 3 in suspension lift | Balanced 33 | No trimming |

*Every upgrade size on our size pages that fits a 15-inch wheel, a 16-inch wheel, a 17-inch wheel, and a 18-inch wheel, placed on the 2nd gen Tacoma ladder above. The "vs" column compares against the tallest size in the 2005-2015 family. "Fits from" is the lowest modeled tier whose ceiling covers the size, matched to a tenth of an inch with a 0.1 in allowance. Intent and clearance work come from the recommender's rule-set and are not generation-specific.*

The sizes the model puts beyond this generation's ladder are 33x10.5R17, 33x12.5R17, 255/80R17, 295/70R17, 285/75R17, 35x12.5R17, 275/70R18, and 285/70R18. Every one of them is at or above 33.0 in, against a top second-gen ceiling of 32.8 in. Fitting them is not impossible — people fabricate — but it sits outside anything this site's rule-set will model for you.

The practical upside of this generation is availability. 4 of its sizes — 245/75R16, 265/70R16, 265/65R17, and 265/60R18 — carry on into the dataset's own rows, appearing on 44 year-and-trim rows across 2017-2023, every one of them a 3rd gen Tacoma row. None of them reaches 2026: the fourth generation moved to a different size set entirely. A second-gen owner replacing like for like is still shopping a size a 2023 truck shipped on, which is not true of the generation before it.

Split the same catalogue by wheel diameter and the second generation's position becomes obvious: three of its four rim sizes are well covered, and only the 15-inch entry has nothing modern behind it. That is the practical difference between this generation and the one before it — a second-gen on its factory wheels is shopping a live catalogue, not a legacy one.

| Wheel | Sizes in the family | Family height range | Catalogued sizes on this wheel |
| --- | --- | --- | --- |
| 15 in | 215/70R15 | 26.9 in to 26.9 in | None in our catalogue |
| 16 in | 245/75R16, 265/70R16 | 30.5 in to 30.6 in | 245/75R16, 265/70R16, 265/75R16, 285/75R16 |
| 17 in | 265/65R17 | 30.6 in to 30.6 in | 245/70R17, 265/65R17, 265/70R17, 275/70R17, 285/70R17 |
| 18 in | 265/60R18, 255/45R18 | 27.0 in to 30.5 in | 265/60R18, 265/65R18, 285/65R18, 265/70R18 |

*The 2005-2015 size family broken out by wheel diameter, against the upgrade sizes this site catalogues on the same wheel and inside this generation's modeled ladder. A wheel with nothing in the last column is one the modern aftermarket has largely left behind, not one that stops working.*

## What does a size change do to a 2nd-gen speedometer?
Four of the six sizes above share a rolling height, so this is the one Tacoma generation where a factory-size swap barely touches the instruments. The table runs every family size and every modeled ceiling against 265/70R16 to show how little moves — and where that stops being true.

| Size | Where it comes from | Overall diameter | Revs per mile | An indicated 60 mph is really | Error vs 265/70R16 |
| --- | --- | --- | --- | --- | --- |
| 215/70R15 | Factory size | 26.9 in | 751 | 53 mph | -12.3% |
| 255/45R18 | Factory size | 27.0 in | 746 | 53 mph | -11.7% |
| 245/75R16 | Factory size | 30.5 in | 662 | 60 mph | -0.5% |
| 265/60R18 | Factory size | 30.5 in | 661 | 60 mph | -0.3% |
| 265/65R17 | Factory size | 30.6 in | 660 | 60 mph | -0.1% |
| 265/70R16 | Factory size, and the modeled stock height ceiling | 30.6 in | 659 | 60 mph | 0.0% |
| 265/75R16 | Modeled leveling kit (1-2 in) ceiling | 31.6 in | 637 | 62 mph | +3.4% |
| 285/75R16 | Modeled 3 in suspension lift ceiling | 32.8 in | 614 | 64 mph | +7.3% |

*Every 2nd-gen factory size plus each modeled ceiling from the ladder above, measured against the tallest size in the 2005-2015 family — 265/70R16 at 30.6 in. The last two columns are what a speedometer and odometer calibrated for that size get wrong on each of the others; the geometry is exact, the calibration assumption is the model.*

Inside the truck cluster the error never leaves a few tenths of a percent, which is inside the tolerance of the gauge itself: those four sizes are genuinely interchangeable as far as the instruments are concerned. Step outside it and the picture changes twice over. The two short entries land 11.7% and more below the baseline, and the 285/75R16 at the top of the ladder sits 7.3% above it. Either of those moves is worth correcting for; swapping between the four cluster sizes is not.

## 2nd gen Tacoma fitment quirks the data actually shows
These are the things the repo's own data says about the second generation. Each one is checkable against the tables above rather than borrowed from forum lore.

- Wheel diameters in the family run 15 in, 16 in, 17 in, and 18 in — the first Tacoma generation here to reach 17- and 18-inch wheels, and the last to still list a 15.
- 4 of these sizes (245/75R16, 265/70R16, 265/65R17, and 265/60R18) appear again, unchanged, in the third-generation family and on 44 of our 2017-2023 trim rows. The size set survived the 2016 generation change intact even though the truck did not — and then did not survive the 2024 one.
- The family holds two size philosophies at once: a 4-size truck cluster around 30.5 in and 2 short low-sidewall entries roughly three inches below it. No later Tacoma generation in this repo mixes the two.
- 3 of the 4 truck-cluster sizes share an identical 10.4 in section width. Across the whole family width spans 8.5 in to 10.4 in — a 2.0 in range, against 3.8 in of height.
- Nothing in the repo attaches any of these sizes to a 2005-2015 model year, trim, cab, or drivetrain, so no page here will tell you what a specific 2011 Tacoma left the factory wearing. Four of them do appear on later rows — that is the 2017-2023 data, not this generation's.

## Why there is no year-by-year 2nd-gen chart
Like the first generation, the second gets no per-year URLs on this site — the year pages begin at 2017, one model year into the third generation. The sizes themselves do have pages, with dimensions, comparisons, and the modern Tacoma trims that still ship them.

4 of the 2nd-gen factory sizes have their own size pages — 245/75R16, 265/70R16, 265/65R17, and 265/60R18 — with full dimensions, revolutions per mile, and every Tacoma trim in our data that ships them.

## Working out your own 2nd-gen tire size
The 4 cluster sizes are close enough in height that choosing between them is mostly a wheel decision, so compare what each one does to width and sidewall before you commit. If you are planning a lift instead, the estimator is the faster route.

- Read the tire and loading placard in the driver's door jamb — on a 2005-2015 truck that is the only per-vehicle source, and it outranks every table on this page.
- Check the sidewall of the tire actually fitted: on a 2005-2015 truck it is often not the size the charts above predict, because previous owners change sizes and rarely update anything else.
- Put your 2nd-gen factory size and whatever you are considering into the tire calculator together — diameter, section width, revolutions per mile, and speedometer error all move as one.
- Run the 2nd-gen generation, your lift, and your wheel offset through the max tire size estimator before you buy rather than after, and compare its answer to the 3-tier ladder above.

## FAQ
### What tire size is a 2nd gen Tacoma?
The sizes documented for the 2005-2015 Tacoma are 215/70R15, 245/75R16, 265/70R16, 265/65R17, 265/60R18, and 255/45R18. Our data holds this as a long-running community-documented pattern, not a verified per-year spec, with no trim or model year attached to any single size, so confirm yours on the driver's door placard or the tire sidewall.

### What is the stock tire size on a 2nd gen Tacoma TRD Off-Road?
We cannot answer that from our data. The second-generation size family is not broken out by trim anywhere in the repo, so any trim-specific claim for these years would be inference dressed up as a spec. The 4 common truck sizes for the generation are 245/75R16, 265/70R16, 265/65R17, and 265/60R18; the placard tells you which one is yours.

### Will 33s fit a 2nd gen Tacoma?
Our fitment model puts 285/75R16 — this generation's 33, about 32.8 in in real height — at the 3-inch lift tier, expecting fender liner trim and cab mount chop for full articulation and a 4.56-4.88 gear set. That is a modeled ceiling from a reviewed matrix, not a measurement taken on a truck.

### What is the biggest tire on a stock 2nd gen Tacoma?
The model's stock-height ceiling for this generation is 265/70R16, about 30.6 in, with no trimming expected. Add a leveling kit and it lists 265/75R16 at 31.6 in with the mud flaps removed. Wheel offset moves both answers before anything else does.

### Do 2nd gen and 3rd gen Tacomas use the same tire sizes?
On paper, largely yes. 4 of the second-generation sizes — 245/75R16, 265/70R16, 265/65R17, and 265/60R18 — are exactly the sizes the third-generation family lists, and the 2017-2023 trim rows in our dataset ship those same four. What changes across the generation break is the clearance around the tire, not the tire.

### Why do two of the 2nd gen sizes look so much smaller?
Because they are. 215/70R15 measures 26.9 in and 255/45R18 measures 27.0 in, against roughly 30.5 in for the four truck sizes. They pair short sidewalls with their wheels, so they belong to a very different setup — and swapping one for a cluster size is a three-inch change in rolling height, not a cosmetic one.

### Which 2nd gen tire size has the most modern choice behind it?
The ones that carried into the generation after this one. 4 second-gen sizes — 245/75R16 on 10 rows, 265/70R16 on 17 rows, 265/65R17 on 7 rows, and 265/60R18 on 10 rows — appear on factory rows in our data across 2017-2023, all of them 3rd gen Tacoma rows; 265/70R16 carries the most. None appears on a 2026 row, so treat "current" as "current through 2023" rather than as a size on the showroom floor today. The two short entries in the family have no rows behind them at all in the years we hold.
