2021 Tacoma SR5 tire size.
The factory tire and wheel package for the 2021 Toyota Tacoma SR5, with dimensions, upgrade sizes, and what fits without a lift.
This page covers the 2021 SR5 and SR together: they share the same factory tire and wheel package. It is the canonical page for that shared package.
Factory tire size
The 2021 Toyota Tacoma SR5 came from the factory with P245/75R16 tires on 16-in styled steel wheels.
- On the 2021 SR5, P245/75R16 measures 30.5 in tall and 9.6 in wide, with a 7.2 in sidewall and 662 revolutions per mile.
- The 2021 SR5 is listed as standard on 4-cylinder only, with the tire recorded as all-season.
- Modeled estimate: a stock-height 3rd gen Tacoma like the 2021 SR5 tops out near 265/70R17 (~31.6 in) on factory offset.

What P245/75R16 measures on a 2021 Tacoma SR5
P245/75R16 is 245 mm wide at a 75 percent sidewall ratio on a 16-inch wheel. Through standard tire math that is 30.5 in of overall diameter, 9.6 in of section width, a 7.2 in sidewall, and about 662 revolutions per mile — the figures behind the 2021 SR5's speedometer calibration. That package is standard on 4-cylinder only, riding 16-in styled steel wheels.
Note the P prefix on the 2021 SR5's factory size (P245/75R16): that is a P-metric passenger-rated tire, not an LT light-truck size. The same 245/75R16 in LT form runs a stiffer casing, a higher load rating, and more weight.
Our data carries 1 further factory configuration under the 2021 SR5: P245/75R16 on 16-in black or dark gray alloy (optional/package-dependent). The size holds across them — what changes is the wheel.
The 2021 SR5 Trail package is a trim of its own, with its own page, so its size is quoted there rather than folded into the SR5's here.
Bigger tires on a 2021 Tacoma SR5
Staying on the factory 16-inch wheel of a 2021 SR5, 2 sizes in our candidate set clear at stock height with no lift and no trimming, and inside the modeled stock ceiling of 31.6 in: 265/70R16 at 30.6 in and 265/75R16 at 31.6 in. Set against the 2021 SR5's P245/75R16, the closest of them comes out 0.1 in taller and 0.8 in wider. Common TRD Off-Road and TRD Pro third-gen factory-class size.
Past that, the 16-inch sizes our set offers a 2021 SR5 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) — 1.7 in taller than the 2021 SR5's P245/75R16. 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 SR5 sits in the 2021 Tacoma lineup
Sorted by factory tire diameter, the 2021 Tacoma trims we cover run from P245/75R16 at 30.5 in (SR and SR5) up to P265/70R16 at 30.6 in (TRD Off-Road, TRD Pro, and SR5 Trail package). The SR5's P245/75R16 is 1st of the 4 distinct sizes in that spread: 6 trims above it run a taller factory tire and nothing runs shorter.
Worth knowing before you shop for a 2021 SR5: The factory package is shared as well — SR5 and SR leave the factory on the same tire and wheel. Practically, a tire and wheel package that fits one of them fits the other, and what separates the trims is equipment rather than fitment.
Top-ranked 245/75R16 tires for a 2021 Tacoma SR5
Our tire dataset scores 17 models available in 245/75R16, the size the 2021 Tacoma SR5 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 245/75R16 for the 2021 SR5 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.

2021 Tacoma SR5 tire questions
Our two sources disagree here, so this page publishes the conservative one. On the 2021 SR5'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 2021 SR5 on 16-in styled steel and 16-in black or dark gray alloy — a 16-inch wheel. Across the whole 2021 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 2021 SR5, P245/75R16 works out to 30.5 in of overall diameter and 9.6 in of section width, on a 16-inch wheel with a 7.2 in sidewall. The math is the standard one: 245 mm of width at a 75 percent ratio gives the sidewall, and diameter is the 16-inch rim plus twice that sidewall. At that size the tire turns about 662 revolutions per mile.
On the 2021 SR5's factory wheel, 265/70R16 is the nearest step up in our candidate set at 30.6 in — common TRD Off-Road and TRD Pro third-gen factory-class size. Our rules rate its fitment risk low from stock height on factory offset, and it clears at stock height with no trimming, inside the modeled ceiling of 31.6 in.
