2020 Tacoma TRD Sport tire size.
The factory tire and wheel package for the 2020 Toyota Tacoma TRD Sport, with dimensions, upgrade sizes, and what fits without a lift.
Factory tire size
Our fitment data puts the 2020 Toyota Tacoma TRD Sport on P265/65R17 tires with 17-in machined 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 2020 TRD Sport, P265/65R17 measures 30.6 in tall and 10.4 in wide, with a 6.8 in sidewall and 660 revolutions per mile.
- The 2020 TRD Sport is listed as likely standard on Access Cab or Double Cab, typical 3rd-gen pattern, with the tire recorded as all-season.
- Modeled estimate: a stock-height 3rd gen Tacoma like the 2020 TRD Sport tops out near 265/70R17 (~31.6 in) on factory offset.
- Common factory pattern — not verified against a year-specific Toyota document.

What P265/65R17 measures on a 2020 Tacoma TRD Sport
P265/65R17 is 265 mm wide at a 65 percent sidewall ratio on a 17-inch wheel. Through standard tire math that is 30.6 in of overall diameter, 10.4 in of section width, a 6.8 in sidewall, and about 660 revolutions per mile — the figures behind the 2020 TRD Sport's speedometer calibration. That package is likely standard on Access Cab or Double Cab, typical 3rd-gen pattern, riding 17-in machined alloy wheels.
Note the P prefix on the 2020 TRD Sport's factory size (P265/65R17): that is a P-metric passenger-rated tire, not an LT light-truck size. The same 265/65R17 in LT form runs a stiffer casing, a higher load rating, and more weight.
No other 2020 Tacoma trim in our data runs P265/65R17. The nearest neighbours on the 2020 chart are Limited on P265/60R18 (the same height) and TRD Off-Road on P265/70R16 (the same height) — the comparison to make if you are cross-shopping trims on tire size.
Bigger tires on a 2020 Tacoma TRD Sport
Staying on the factory 17-inch wheel of a 2020 TRD Sport, 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: 265/70R17 at 31.6 in. Set against the 2020 TRD Sport's P265/65R17, the closest of them comes out 1.0 in taller and the same width. A common 17-inch all-terrain baseline on fourth-gen off-road trims.
Past that, the 17-inch sizes our set offers a 2020 TRD Sport need suspension or clearance work: 275/70R17 (32.2 in) clears at factory height but is rated for minor changes, 285/70R17 (32.7 in) sits behind a level / 1-2 in setup with minor changes, and 33x10.5R17 (33.0 in) sits behind a level / 1-2 in 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 2020 TRD Sport's P265/65R17. 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 Sport sits in the 2020 Tacoma lineup
Sorted by factory tire diameter, the 2020 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 Sport's P265/65R17 is 3rd of the 4 distinct sizes in that spread: nothing else in the 2020 range we cover leaves the factory on a taller tire.
A caution for 2020: this model year is not proven against a year-specific Toyota document, so read the size above as the common factory pattern for a 2020 TRD Sport, not a verified trim-level spec. 2017 through 2020 share the same factory tire lineup, and 2020 sits inside that span. The door-jamb placard and the sidewall on the truck settle it.
Top-ranked 265/65R17 tires for a 2020 Tacoma TRD Sport
Our tire dataset scores 18 models available in 265/65R17, the size the 2020 Tacoma TRD Sport runs from the factory on all-season. Below are the 3 best-ranked highway / all-season 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.

Scores are a 0-10 editorial synthesis of published reviews, manufacturer specifications, and retailer fitment data — not tires we tested ourselves. Availability in 265/65R17 for the 2020 TRD Sport 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.

2020 Tacoma TRD Sport tire questions
Our two sources disagree here, so this page publishes the conservative one. On the 2020 TRD Sport's factory wheel the nearest 33-class size in our candidate set is 285/70R17 at 32.7 in, and our per-size rules put it behind a level / 1-2 in 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 2020 TRD Sport on 17-in machined alloy — a 17-inch wheel. Across the whole 2020 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 2020 TRD Sport, P265/65R17 works out to 30.6 in of overall diameter and 10.4 in of section width, on a 17-inch wheel with a 6.8 in sidewall. The math is the standard one: 265 mm of width at a 65 percent ratio gives the sidewall, and diameter is the 17-inch rim plus twice that sidewall. At that size the tire turns about 660 revolutions per mile.
Open the driver's door of the TRD Sport 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 2020 we treat the TRD Sport mapping as the common factory pattern rather than a sourced trim-level spec, so the placard outranks any table, including this one.
