2025 Tacoma SR tire size.
The factory tire and wheel package for the 2025 Toyota Tacoma SR, with dimensions, upgrade sizes, and what fits without a lift.
This page covers the 2025 SR and SR5 together: they share the same factory tire and wheel package. The 2025 SR5 page is the canonical one for that shared package.
Factory tire size
Our fitment data puts the 2025 Toyota Tacoma SR on 245/70R17 tires with 17-in steel or styled 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 2025 SR, 245/70R17 measures 30.5 in tall and 9.6 in wide, with a 6.8 in sidewall and 661 revolutions per mile.
- The 2025 SR is listed as likely standard by trim/configuration on base 17-in tire configurations, with the tire recorded as all-season.
- Modeled estimate: the generation matrix puts a stock-height 4th gen Tacoma near 285/70R17 (33s), but our per-size rules put 285/70R17 behind a level / 1-2 in setup — this 2025 SR page publishes the conservative tier.
- Common factory pattern — not verified against a year-specific Toyota document.

What 245/70R17 measures on a 2025 Tacoma SR
245/70R17 is 245 mm wide at a 70 percent sidewall ratio on a 17-inch wheel. Through standard tire math that is 30.5 in of overall diameter, 9.6 in of section width, a 6.8 in sidewall, and about 661 revolutions per mile — the figures behind the 2025 SR's speedometer calibration. That package is likely standard by trim/configuration on base 17-in tire configurations, riding 17-in steel or styled alloy wheels.
Bigger tires on a 2025 Tacoma SR
Staying on the factory 17-inch wheel of a 2025 SR, 2 sizes in our candidate set clear at stock height with no lift and no trimming, and inside the modeled stock ceiling of 32.7 in: 265/65R17 at 30.6 in and 265/70R17 at 31.6 in. Set against the 2025 SR's 245/70R17, the closest of them comes out 0.1 in taller and 0.8 in wider. Stock-like 17-inch size for earlier TRD Sport-style setups.
Past that, the 17-inch sizes our set offers a 2025 SR 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 4th gen Tacoma at 285/75R17 (skinny 34s, about 34.0 in) — 3.5 in taller than the 2025 SR's 245/70R17. Clearance work it lists: Crash-plate removal (2 bolts, reversible); gearing flagged at 4.88 if sluggish. Crash-plate removal replaces the permanent 3rd-gen cab mount chop. These are modeled estimates, not measured installs: offset, alignment, and the tire's real moulded size all move the answer.
Where the SR sits in the 2025 Tacoma lineup
Sorted by factory tire diameter, the 2025 Tacoma trims we cover run from 245/70R17 at 30.5 in (SR and SR5) up to a nominal 33 in tire (TRD Off-Road i-FORCE MAX, Trailhunter, and TRD Pro). The SR's 245/70R17 is 1st of the 4 distinct sizes in that spread: 7 trims above it run a taller factory tire and nothing runs shorter.
A caution for 2025: this model year is not proven against a year-specific Toyota document, so read the size above as the common factory pattern for a 2025 SR, not a verified trim-level spec. The factory package is shared as well — SR and SR5 leave the factory on the same tire and wheel. The door-jamb placard and the sidewall on the truck settle it.
Top-ranked 245/70R17 tires for a 2025 Tacoma SR
Our tire dataset scores 14 models available in 245/70R17, the size the 2025 Tacoma SR 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 245/70R17 for the 2025 SR 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.

2025 Tacoma SR tire questions
Our two sources disagree here, so this page publishes the conservative one. On the 2025 SR'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 4th gen Tacoma at 285/70R17 (33s, about 32.7 in). Plan for the leveling kit, and treat both as modeled estimates rather than installs we measured.
Our data lists the 2025 SR on 17-in steel or styled alloy — a 17-inch wheel. Across the whole 2025 range we cover 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 2025 SR, 245/70R17 works out to 30.5 in of overall diameter and 9.6 in of section width, on a 17-inch wheel with a 6.8 in sidewall. The math is the standard one: 245 mm of width at a 70 percent ratio gives the sidewall, and diameter is the 17-inch rim plus twice that sidewall. At that size the tire turns about 661 revolutions per mile.
Open the driver's door of the SR 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 2025 we treat the SR mapping as the common factory pattern rather than a sourced trim-level spec, so the placard outranks any table, including this one.
