2026 Tacoma SR5 tire size.
The factory tire and wheel package for the 2026 Toyota Tacoma SR5, with dimensions, upgrade sizes, and what fits without a lift.
Factory tire size
The 2026 Toyota Tacoma SR5 came from the factory with 245/70R17 tires on 17-in styled alloy wheels.
- On the 2026 SR5, 245/70R17 measures 30.5 in tall and 9.6 in wide, with a 6.8 in sidewall and 661 revolutions per mile.
- The 2026 SR5 is listed as standard on all listed 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 2026 SR5 page publishes the conservative tier.

What 245/70R17 measures on a 2026 Tacoma SR5
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 2026 SR5's speedometer calibration. That package is standard on all listed configurations, riding 17-in styled alloy wheels.
245/70R17 is not exclusive to the SR5 in 2026: SR 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 2026 Tacoma SR5
Staying on the factory 17-inch wheel of a 2026 SR5, 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 2026 SR5'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 2026 SR5 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 2026 SR5'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 SR5 sits in the 2026 Tacoma lineup
Sorted by factory tire diameter, the 2026 Tacoma trims we cover run from 245/70R17 at 30.5 in (SR and SR5) up to 265/70R18 at 32.6 in (TRD Off-Road i-FORCE MAX, Trailhunter, and TRD Pro). The SR5'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.
Top-ranked 245/70R17 tires for a 2026 Tacoma SR5
Our tire dataset scores 14 models available in 245/70R17, the size the 2026 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 245/70R17 for the 2026 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.

2026 Tacoma SR5 tire questions
Our two sources disagree here, so this page publishes the conservative one. On the 2026 SR5'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 2026 SR5 on 17-in styled alloy — a 17-inch wheel. Across the whole 2026 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 2026 SR5, 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.
On the 2026 SR5's factory wheel, 265/65R17 is the nearest step up in our candidate set at 30.6 in — stock-like 17-inch size for earlier TRD Sport-style setups. 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 32.7 in.
