2018 Tacoma TRD Off-Road tire size.
The factory tire and wheel package for the 2018 Toyota Tacoma TRD Off-Road, with dimensions, upgrade sizes, and what fits without a lift.
Factory tire size
Our fitment data puts the 2018 Toyota Tacoma TRD Off-Road on P265/70R16 tires with 16-in machined contrast alloy wheels — the common factory pattern for this model year rather than a trim mapping we can source. Confirm the exact size on the driver's door placard or the tire sidewall before you buy.
- On the 2018 TRD Off-Road, P265/70R16 measures 30.6 in tall and 10.4 in wide, with a 7.3 in sidewall and 659 revolutions per mile.
- The 2018 TRD Off-Road is listed as likely standard on Access Cab or Double Cab, typical 3rd-gen pattern, with the tire recorded as all-terrain or all-season by package/year.
- Modeled estimate: a stock-height 3rd gen Tacoma like the 2018 TRD Off-Road tops out near 265/70R17 (~31.6 in) on factory offset.
- Common factory pattern — not verified against a year-specific Toyota document.

What P265/70R16 measures on a 2018 Tacoma TRD Off-Road
P265/70R16 is 265 mm wide at a 70 percent sidewall ratio on a 16-inch wheel. Through standard tire math that is 30.6 in of overall diameter, 10.4 in of section width, a 7.3 in sidewall, and about 659 revolutions per mile — the figures behind the 2018 TRD Off-Road's speedometer calibration. That package is likely standard on Access Cab or Double Cab, typical 3rd-gen pattern, riding 16-in machined contrast alloy wheels.
Note the P prefix on the 2018 TRD Off-Road's factory size (P265/70R16): that is a P-metric passenger-rated tire, not an LT light-truck size. The same 265/70R16 in LT form runs a stiffer casing, a higher load rating, and more weight.
P265/70R16 is not exclusive to the TRD Off-Road in 2018: TRD Pro runs it too. Wheel finish, package content, and drivetrain separate those trims rather than tire size, so a tire that fits one fits the others.
Bigger tires on a 2018 Tacoma TRD Off-Road
Staying on the factory 16-inch wheel of a 2018 TRD Off-Road, 1 size in our candidate set clears at stock height with no lift and no trimming, and inside the modeled stock ceiling of 31.6 in: 265/75R16 at 31.6 in. Set against the 2018 TRD Off-Road's P265/70R16, the closest of them comes out 1.0 in taller and the same width. A small 16-inch step up that keeps width close to stock.
Past that, the 16-inch sizes our set offers a 2018 TRD Off-Road need suspension or clearance work: 285/75R16 (32.8 in) sits behind a 2-3 in lift setup with minor changes. Those tiers come from our fitment rule-set, not a truck we measured; lower-offset wheels push each one harder into the fender.
Add a leveling kit and our generation fitment matrix estimates a 3rd gen Tacoma at 275/70R17 (~32.2 in) — 1.6 in taller than the 2018 TRD Off-Road's P265/70R16. Clearance work it lists: Remove mud flaps. 285/70R17 (33s) fits street-only with fender-liner trim + heat gun, but rubs off-road at full lock. These are modeled estimates, not measured installs: offset, alignment, and the tire's real moulded size all move the answer.
Where the TRD Off-Road sits in the 2018 Tacoma lineup
Sorted by factory tire diameter, the 2018 Tacoma trims we cover run from P245/75R16 at 30.5 in (SR and SR5 4-cylinder) up to P265/70R16 at 30.6 in (TRD Off-Road and TRD Pro). The TRD Off-Road's P265/70R16 is 4th of the 4 distinct sizes in that spread: nothing else in the 2018 range we cover leaves the factory on a taller tire.
A caution for 2018: this model year is not proven against a year-specific Toyota document, so read the size above as the common factory pattern for a 2018 TRD Off-Road, not a verified trim-level spec. 2017 through 2020 share the same factory tire lineup, and 2018 sits inside that span. The door-jamb placard and the sidewall on the truck settle it.
Top-ranked 265/70R16 tires for a 2018 Tacoma TRD Off-Road
Our tire dataset scores 19 models available in 265/70R16, the size the 2018 Tacoma TRD Off-Road runs from the factory on all-terrain or all-season by package/year. Below are the 3 best-ranked all-terrain models in that size, plus mild all-terrain pick Destination A/T2 as a deliberate contrast — it scores differently because it is built for a different job.
All-Terrain
Best for daily all weather, moderate trail, snow.
All-Terrain
Best for value, daily all weather, light trail.
Mild All-Terrain

Scores are a 0-10 editorial synthesis of published reviews, manufacturer specifications, and retailer fitment data — not tires we tested ourselves. Availability in 265/70R16 for the 2018 TRD Off-Road comes from that dataset's own size catalog, and the shortlist follows the dataset's editorial rank — the 0-10 figure beside each pick is the blended score, one input to that rank rather than the thing it sorts on, so a model further down the rank can carry a higher number.

2018 Tacoma TRD Off-Road tire questions
Our two sources disagree here, so this page publishes the conservative one. On the 2018 TRD Off-Road's factory wheel the nearest 33-class size in our candidate set is 285/75R16 at 32.8 in, and our per-size rules put it behind a 2-3 in lift setup with minor changes; the generation matrix is looser, putting a stock-height 3rd gen Tacoma at 265/70R17 (~31.6 in). Plan for the leveling kit, and treat both as modeled estimates rather than installs we measured.
Our data lists the 2018 TRD Off-Road on 16-in machined contrast alloy — a 16-inch wheel. Across the whole 2018 range we cover 16-inch, 17-inch, and 18-inch wheels, so wheel diameter is one of the things that changes between trims. Keeping the factory diameter keeps the sidewall the truck was tuned for, and it keeps the tire choices in our size data open to you.
On a 2018 TRD Off-Road, P265/70R16 works out to 30.6 in of overall diameter and 10.4 in of section width, on a 16-inch wheel with a 7.3 in sidewall. The math is the standard one: 265 mm of width at a 70 percent ratio gives the sidewall, and diameter is the 16-inch rim plus twice that sidewall. At that size the tire turns about 659 revolutions per mile.
Open the driver's door of the TRD Off-Road and read the tire and loading information placard on the door jamb: it carries the original tire size and the cold inflation pressures set for it. Then read the sidewall of the tire actually fitted, since a previous owner may have changed sizes. For 2018 we treat the TRD Off-Road mapping as the common factory pattern rather than a sourced trim-level spec, so the placard outranks any table, including this one.
