Toyota Tundra Tire Size Guide: OEM, Plus-One & Off-Road Options

You're standing in the tire shop parking lot, sticker in hand, and the guy behind the counter is asking what size you run. Your 2019 Tundra CrewMax came with 275/65R18s from the factory. But the lifted rig two bays over is wearing something much beefier, and now you're second-guessing yourself. Before you guess, or worse, buy the wrong set, here's every factory tire size Toyota put on the Tundra from 2000 through 2024. Plus a plain-English breakdown of when to go bigger and what actually fits without rubbing.

Most Tundras leave the factory on 275/65R18 or 265/70R17 tires depending on trim and year. The 2022-2024 Tundra SR5 runs 275/65R18, and the TRD Pro does too. A plus-one upgrade to 285/65R18 adds roughly half an inch of sidewall without a lift. Off-road builds commonly run 285/70R18 or 305/70R17 with a 2-inch leveling kit. Always verify load index before buying.

Factory Tundra Tire Sizes by Year and Trim

Toyota changed the Tundra's wheel and tire setup more times than most owners realize. The first-gen trucks rode on 16-inch wheels. The third-gen Limited rolls on 22-inch wheels. That's a big spread, and it matters when you start shopping replacements.

Here's the factory breakdown by generation and trim:

Generation	Years	Trim	Factory Tire Size	Wheel
1st Gen	2000-2006	Base / SR5	245/70R16	16x7
1st Gen	2003-2006	Limited	265/65R17	17x7.5
2nd Gen	2007-2013	SR5 / Limited	275/65R18	18x8
2nd Gen	2014-2021	SR	245/70R17	17x7.5
2nd Gen	2014-2021	SR5 / TRD	275/65R18	18x8
2nd Gen	2014-2021	1794 / Platinum	275/55R20	20x8
2nd Gen	2015-2021	TRD Pro	275/65R18	18x8
3rd Gen	2022-2024	SR / SR5 / TRD	265/70R18 or 275/65R18	18x8
3rd Gen	2022-2024	Limited / Platinum / 1794	265/60R20	20x8
3rd Gen	2022-2024	Capstone	265/55R22	22x9
3rd Gen	2022-2024	TRD Pro	285/65R18	18x8.5

A couple of things jump out. The TRD Pro is the only third-gen trim that ships with a 33-inch tire from the factory. The 285/65R18 measures right at 32.6 inches. The 1794 and Platinum trims got pushed onto low-profile 20s and 22s, which look great but ride firm.

Verify your exact size on the driver's door jamb sticker before ordering. Trim names get reshuffled mid-cycle, and the sticker doesn't lie. You can also cross-check on the Toyota spec page for your year.

If you're working on a first-gen and the interior is showing its age, the 2000 Toyota Tundra seat cover options cover that exact body style.

How to Read a Tundra Tire Size Code

Pull a tire sidewall and you'll see something like P275/65R18 116T. Each chunk tells you something specific.

• P = passenger-rated. LT means light truck, which carries higher load ratings.
• 275 = section width in millimeters (tread-to-sidewall measurement).
• 65 = aspect ratio. Sidewall height is 65% of the section width. A 275/65 has a sidewall of about 179mm, or 7 inches.
• R = radial construction. Pretty much every modern tire uses this.
• 18 = rim diameter in inches.
• 116 = load index. 116 carries 2,756 lbs per tire.
• T = speed rating (118 mph in this case).

Two tires with the same rim diameter can have wildly different overall heights. A 275/65R18 stands 32.1 inches tall. A 275/55R20 stands 31.9 inches tall, even on a bigger rim, because the sidewall shrank. That's why "20-inch wheels" doesn't automatically mean "taller truck."

Load index is the one most folks skip. A Tundra has a GVWR around 7,200 lbs. If you swap to a tire rated below the factory load index, you've technically downgraded the truck's hauling rating. Stick with the factory load number or go higher.

275 vs 285 Tundra Tires: What Actually Changes

This is the most common question on Tundra forums, and the answer isn't just "10mm wider."

A 285/65R18 is 10mm wider in section width and stands about 0.4 inches taller overall (32.6 vs 32.1 inches). That extra height bumps your speedometer reading low by roughly 1.3% at 70 mph. When your dash says 70, you're actually doing about 70.9. Not huge, but if you're chasing real mileage tracking, recalibrate.

Will a 285/65R18 fit a stock Tundra without rubbing? In most second-gen and third-gen cases, yes. The lower control arm and inner fender liner have enough room at ride height. Full-lock steering on a tight parking-lot turn can get close on some CrewMax configurations, especially with aftermarket wheels that have an aggressive offset.

The trade-off is real-world MPG. Wider tread plus heavier construction usually costs 0.5 to 1 MPG. Owners who swapped 275s for 285 all-terrain tires saw 14.5 turn into 13.8 on the same commute.

If you tow heavy or run hot Texas asphalt in July, the wider footprint is worth the gas penalty. If you mostly highway-cruise, the 275 stays the smarter buy.

Plus-One Upgrades: Going Bigger Without a Lift

Plus-one sizing means jumping one inch in rim diameter while dropping the sidewall to keep the overall tire height roughly the same. The goal is a sharper look without messing with speedometer accuracy or suspension geometry.

On a Tundra, the common plus-one moves are:

• 275/65R18 → 275/60R20: Same overall height, lower profile, more rim showing. Looks good, rides a bit firmer.
• 275/65R18 → 285/65R18: Same rim, bigger tire. Easiest swap, no wheel cost.
• 265/70R17 → 285/65R18: Real upgrade if you're moving up trim level wheels.

For stock-suspension trucks, you can usually clear a 285/65R18 or a 285/70R17 without any modifications. Push past that, and you start running into the front bumper valance, the inner fender liner near full lock, or the upper control arm at full droop.

A 1.5-inch to 2-inch leveling kit changes the math. With the front end lifted to match the rear, you can clear a 285/70R18 (33.1 inches tall) cleanly. That's the sweet spot a lot of second-gen owners settle on, and it's what most TRD Pro builds chase.

Off-Road Tire Options for the Tundra

If you actually use your Tundra off pavement, the tire choice changes more than the size does. Tread pattern is half the story.

All-Terrain (AT) Tires

All-terrain tires are the daily-driver compromise. They handle dirt roads, light mud, gravel, and snow without screaming on the highway. Common Tundra setups:

• 285/70R18 (33 inches), needs a 1.5 to 2-inch level on stock suspension.
• 285/75R17 (33.8 inches), needs a 2-inch level minimum.
• 305/70R17 (33.8 inches), wider stance, same height, needs trimming on some second-gens.

The factory TRD Pro tire (285/65R18) is a good baseline reference. Toyota engineered the truck around that size, so it's the safest aggressive choice if you want a real 33 with no surprises.

Mud-Terrain (MT) Tires

Mud-terrain tires trade highway manners for traction in wet clay, deep mud, and rocky climbs. They're louder, wear faster, and drop fuel economy another 1 to 2 MPG over all-terrain options. Sizes are the same as all-terrain options, but the tread is chunkier and the sidewalls are usually stiffer.

For pure trail rigs, owners run 35x12.50R17 on a 4-inch lift with aftermarket upper control arms. That's a real 35-inch tire, and getting there on a Tundra requires geometry corrections, not just spacers.

For a daily-driver that sees weekend trails, stick with a 33-inch all-terrain. You'll thank yourself on the highway home.

Tundra Wheel and Bolt Pattern Specs

The Tundra has the same bolt pattern across every generation, and it's not shared with any other Toyota.

Spec	Measurement
Bolt Pattern	5x150mm
Center Bore	110.1mm
Stock Offset Range	+30 to +60mm
Lug Nut Size	M14x1.5
Stock Wheel Widths	7.0" to 9.0"

That 5x150 pattern is the same as the Land Cruiser and Lexus LX, but not the Tacoma (5x114.3) or 4Runner (6x139.7). Cross-shopping aftermarket wheels means filtering specifically for 5x150 fitment, or you'll waste a week of shipping.

Center bore matters too. The Tundra's hub is 110.1mm. If you buy wheels with a larger center bore, you need hub-centric rings to keep the wheel centered. Skip them and you'll feel a steering wheel vibration around 55 mph.

Offset controls how far the wheel pokes out. Stock is roughly +30 to +60mm depending on year and trim. Going to a lower offset (like 0mm or -12mm) pushes the wheel outward, which looks aggressive but adds stress to wheel bearings and ball joints over time.

While you're sizing accessories, the right steering wheel cover size for your truck follows the same fit-first logic.

What Happens to Your Tundra When Tires Don't Fit Right

Buying the wrong size doesn't always show up in the parking lot. Sometimes it shows up at 65 mph on the freeway.

Rubbing at full lock is the classic one. On second-gen Tundras, the inner fender liner is the first thing that catches a 35. On third-gens, the upper control arm and steering knuckle clearance is tighter than the second-gen. You'll hear it as a thunk when you crank the wheel hard in a parking lot.

Speedometer error stacks up fast. A 1-inch taller tire reads about 3% slow on the speedo. Cops calibrate radar against the real ground speed, not yours. If you tell the shop you have 33s, they should recalibrate at the same visit.

TPMS sensors stay valid across most rim swaps as long as the sensor's frequency matches. Going from a stock 18 to an aftermarket 18 is usually a non-issue. Going from a TPMS-equipped wheel to one without a sensor mount means you'll see the dashboard light forever.

Load index downgrades can void your truck's GVWR rating. If you tow 9,000 lbs and run P-rated tires under the factory load index, you're outside the truck's design envelope and your insurance knows it.

Keeping the Rest of Your Tundra in Shape

Tire swap day is messy. You're climbing in and out of the cab with wet boots, dropping wrenches on the floor mat, and tracking trail dust onto the driver's seat. After three or four of those days, the factory cloth starts to look like a job site.

Most folks who use their Tundra hard end up protecting the interior the same way they protect the underside, with the right gear sized to the truck. Made-to-fit seat covers for the Toyota Tundra wrap the seats in eco-leather or heavy fabric that wipes clean. They're airbag-safe, install in under an hour with the seat in place, and run around half of what a dealership reupholstery quote costs.

If you're shopping across multiple work trucks, truck seat covers built for work and trail use cover the broader lineup. The Luxury Seat Covers product page has the material breakdowns and color options. Same attention to fitment you just put into your tires, applied to the interior.

And if you've ever wondered whether steering wheel covers are one-size-fits-all, the short answer is no, and the long answer is on that page.

Frequently Asked Questions

Q: What is the difference between 275 and 285 Tundra tires?

The 285 is 10mm wider and stands about 0.4 inches taller in overall diameter. On an 18-inch rim with a 65-series sidewall, the 285/65R18 clears a stock Tundra without rubbing in most cases. Full-lock steering can be tight on CrewMax cabs with aggressive wheel offsets. The 275 gives slightly better MPG and quieter highway cruising. The 285 gives better traction, more sidewall, and a fuller stance under the fender.

Q: What size tires come stock on a 2022 Toyota Tundra?

The 2022 Tundra SR5 ships on 275/65R18 tires. The TRD Off-Road and TRD Pro also run an 18-inch wheel, but the TRD Pro steps up to a 285/65R18 from the factory. The Limited, Platinum, and 1794 trims move to 20-inch wheels with 265/60R20 tires. The Capstone runs 22-inch wheels with 265/55R22. Always check the door jamb sticker on your specific truck to confirm.

Q: Will 33-inch tires fit a stock Toyota Tundra?

A true 33-inch tire like a 285/70R17 fits a stock second-gen Tundra with minor trimming or a 1.5-inch leveling kit. On the third-gen (2022 and newer), the front suspension geometry is different and a 2-inch level is the safer starting point before running 33s. The TRD Pro already runs a 33 from the factory (285/65R18), so that exact size is a known-good fit on any 3rd-gen with stock geometry.

Q: What is the bolt pattern on a Toyota Tundra?

All Toyota Tundra trucks from 2000 through 2024 use a 5x150mm bolt pattern. The center bore is 110.1mm and the lug nuts are M14x1.5. This pattern is unique to the Tundra in the Toyota truck lineup. It does not share fitment with the Tacoma (5x114.3mm) or the 4Runner (6x139.7mm). When shopping aftermarket wheels, filter specifically for 5x150 or you'll waste shipping.

Q: Do bigger tires affect Toyota Tundra fuel economy?

Yes. Moving from a 275/65R18 to a 285/70R18 adds rotational mass and rolling resistance. Real-world Tundra owners typically report a drop of 0.5 to 1.5 MPG depending on tire weight, tread pattern, and driving habits. Mud-terrain tires hit MPG harder than all-terrain tires because of the deeper voids and stiffer sidewalls. Highway-driven trucks feel it more than mixed-use trucks, since rolling resistance matters most at sustained speed.

Q: What is the largest tire I can fit on a Tundra without a lift?

On a second-gen Tundra (2007-2021), most owners fit 285/65R18 or 285/70R17 without any lift, and some squeeze in 285/70R18 with minor fender liner trimming. A 1.5-inch leveling kit cleanly opens the door to 285/70R18 (33 inches). Third-gen owners generally need at least a 2-inch level to clear 285/70R18 without rubbing at full lock or full droop. The factory TRD Pro 285/65R18 is the safest no-mod 33.
