Tacoma Tire Size Guide: Stock Sizes by Year, Trim & Upgrade Options
Everything a Toyota Tacoma owner needs to find the right tire size, read the numbers, and choose a safe upgrade.
Finding the correct Tacoma tire size sounds simple until a few details get in the way. The truck has been sold for nearly three decades, across four generations, with more than a dozen trims. A 2005 Tacoma, a 2019 Tacoma, and a 2024 Tacoma do not all wear the same tires.
This guide lays out the stock Toyota Tacoma tire size by generation and trim, explains how to read a tire sidewall, shows how a tire size calculator works, and covers the popular 33-inch upgrade. It also points out the mistakes that cost owners money.
How to Find Your Tacoma Tire Size in 60 Seconds
Skip the guesswork. Three places give the right answer, and the first two are free.
1. Check the door jamb placard
Open the driver’s door and look for a white and yellow sticker on the frame. It lists the factory tire size and the recommended cold tire pressure. This is the most reliable source for the truck as it left the factory.
2. Read the sidewall of the tire itself
The size is molded into the rubber, for example 265/70R16. This matters because a previous owner may have changed the tires or wheels. The sidewall shows what is on the truck today, not what Toyota installed.
3. Look in the owner’s manual
The manual lists approved tire sizes and load requirements for each trim and wheel option.
How to Read a Tire Size (265/70R16 Explained)
Every number and letter on the sidewall has a meaning. Once these are clear, the rest of the guide gets easier.
| Part | Meaning | Example |
|---|---|---|
| 265 | Section width in millimeters (about 10.4 inches) | Wider number = wider contact patch |
| 70 | Aspect ratio: sidewall height as a percentage of width | 70% of 265 mm = 185.5 mm |
| R | Radial construction | Standard on modern passenger and light-truck tires |
| 16 | Wheel diameter in inches | Must match your wheel exactly |
| 112 | Load index (maximum weight per tire) | Higher = more capacity |
| T | Speed rating | T is rated to 118 mph |
The load index deserves extra attention on a truck that tows or hauls. A lower rating than stock can put the tire under stress. For a deeper explanation, read this guide to tire load rating before buying.
Stock Tacoma Tire Size by Generation and Year
Toyota has used different wheel diameters and tire sizes in each generation. The tables below show the most common factory sizes. Trim, cab, and package choices can change the exact fitment, so always confirm against the door placard.
Fourth Generation (2024 – Present)
The redesigned Tacoma moved to larger wheels and taller sidewalls across the lineup. Based on published fitment data for the 2024 and 2025 model years, these are the factory sizes:
| Trim | Stock Tire Size | Wheel |
|---|---|---|
| SR / SR5 | 245/70R17 | 17-inch |
| TRD PreRunner | 265/70R17 | 17-inch |
| TRD Off-Road | 265/70R17 | 17-inch |
| TRD Sport | 265/65R18 | 18-inch |
| Limited | 265/65R18 | 18-inch |
| TRD Pro | 265/70R18 | 18-inch |
| Trailhunter | 265/70R18 | 18-inch |
Owners searching for a 2023 Toyota Tacoma tire size should note the dividing line: the 2023 truck still belongs to the third generation, while the 2024 model is the first of the fourth.
Third Generation (2016 – 2023)
This is the generation behind many popular searches, including the 2017, 2018, 2019, 2020, 2021, 2022 and 2023 Tacoma tire size. The lineup stayed consistent for years:
| Trim | Typical Stock Tire Size | Wheel |
|---|---|---|
| SR | 245/75R16 | 16-inch |
| SR5 / TRD Sport (17-inch package) | 265/65R17 | 17-inch |
| TRD Off-Road | 265/70R16 (some packages 265/65R17) | 16 or 17-inch |
| Limited | 265/60R18 | 18-inch |
| TRD Pro | 265/70R16 | 16-inch |
Second Generation (2005 – 2015)
Owners of an older truck searching for a 2015 Toyota Tacoma tire size or a 2005 Toyota Tacoma tire size will find a wider spread. Common factory sizes across this generation include:
- 225/75R15 on some early base models
- 245/75R16 on many 4×4 and base models
- 265/70R16 on SR5 and TRD Off-Road setups
- 265/65R17 and 265/60R18 on sport and upper trims in later years
Because aftermarket wheels are so common on trucks this old, the sidewall check matters most here.
First Generation (1995 – 2004)
The original Tacoma used smaller wheels, commonly 15 or 16 inches, with tire sizes such as 205/75R15, 235/75R15, and 245/75R16. Replacement choices are more limited in some of these sizes, so shop early if the truck needs tires soon.
Tacoma Tire Size Calculator: The Math Behind It
A tire size calculator compares two sizes and tells you how much taller, wider, or faster-reading the new one is. It is useful before buying, because a tire that looks close on paper can rub or throw off the speedometer.
The overall diameter formula
Overall diameter in inches equals the wheel diameter plus two sidewalls:
Diameter = wheel size + 2 × (width × aspect ratio ÷ 100 ÷ 25.4)
Worked example: 265/70R17
- Sidewall height = 265 × 0.70 = 185.5 mm
- Convert to inches = 185.5 ÷ 25.4 = 7.30 inches
- Two sidewalls = 14.61 inches
- Add the 17-inch wheel = about 31.6 inches tall
| Tire Size | Approx. Diameter | Change vs. 265/70R17 |
|---|---|---|
| 245/75R16 | 30.5 in | -1.1 in |
| 265/65R17 | 30.6 in | -1.1 in |
| 265/60R18 | 30.5 in | -1.1 in |
| 265/70R17 (stock) | 31.6 in | 0 |
| 265/65R18 | 31.6 in | 0 |
| 275/70R17 | 32.2 in | +0.6 in |
| 265/70R18 | 32.6 in | +1.0 in |
| 285/70R17 | 32.7 in | +1.1 in |
Why speedometer error matters
A taller tire covers more ground per rotation, so the speedometer reads lower than your true speed. Moving from a 30.5-inch tire to a 32.7-inch tire is about a 7% change. At a true 70 mph, the dash would show roughly 65 mph. That affects speeding risk, odometer accuracy, and fuel economy calculations.
Upgrading Your Tacoma Tire Size: 31, 32 and 33-Inch Options
Many Tacoma owners eventually ask the same question: can bigger tires fit? Often the answer is yes, with a few trade-offs.
Stay near stock
Choose a plus-sized or equivalent tire. This keeps handling, braking, and fuel economy close to factory levels and avoids rubbing.
Modest step up
Sizes around 31.5 to 32 inches often fit with little or no modification, depending on wheel offset and suspension height.
The 33-inch jump
Sizes like 285/70R17 look great and add traction off-road, but usually call for a lift, trimming, or both.
What a 33-inch tire usually requires
- Suspension lift: commonly a 2 to 3 inch lift for proper clearance
- Possible trimming of the front bumper cover or inner fender liners
- Wheel offset check to prevent rubbing at full steering lock
- Speedometer recalibration to correct the reading
- Possible regearing if the truck feels sluggish, especially when towing
Wheel specs that stay the same
Tacomas use a 6×139.7 mm (6×5.5 inch) bolt pattern. Aftermarket wheels must match it, along with correct offset and center bore.
Choosing the Right Tire Type for Your Tacoma
Size is only half the decision. The tread style decides how the truck behaves in rain, sand, mud, and snow.
| Type | Best For | Pros | Cons |
|---|---|---|---|
| Highway-terrain (H/T) | Commuting, long highway miles | Quiet, efficient, long tread life | Limited off-road grip |
| All-terrain (A/T) | Mixed daily driving and trails | Balanced traction and comfort | Slightly louder, a bit less efficient |
| Mud-terrain (M/T) | Serious off-roading | Maximum grip in mud and rock | Noisy, wears faster, weaker on wet pavement |
For most owners, an all-terrain tire is the sweet spot. Popular choices include the Falken Wildpeak A/T3W, its newer sibling the Falken Wildpeak A/T4W, and the Nitto Ridge Grappler, which blends aggressive looks with road manners. You can also browse more options on our tire brands page.
Common Mistakes When Choosing a Tacoma Tire Size
- Copying a friend’s size. A different trim or wheel can need something else.
- Ignoring load range. A tire that fits can still be wrong for towing or payload.
- Mixing sizes. Uneven tires strain a 4×4 drivetrain. Replace in sets or follow a professional’s advice.
- Forgetting the TPMS. Changing wheels can mean moving or reprogramming sensors. Learn how tire pressure sensors work so the dash light does not surprise you.
- Skipping rotation. Even wear protects your investment. Four-wheel-drive owners should read about AWD and 4×4 tire rotation.
- Ignoring installation cost. Budget for mounting and balancing, and see typical tire balancing prices before you shop.
Where to Buy and Install Tacoma Tires
Once the size is settled, compare price, warranty, and installation. National retailers often run seasonal promotions, so check offers like the Costco Michelin tire sale or a Discount Tire coupon code before paying full price. If convenience matters, review Walmart tire installation details too.

Frequently Asked Questions About Tacoma Tire Size
What is the stock tire size for a Toyota Tacoma?
It depends on year and trim. Many 2016–2023 trucks use 245/75R16, 265/70R16, 265/65R17, or 265/60R18, while 2024 and newer trucks commonly use 245/70R17, 265/70R17, 265/65R18, or 265/70R18. Check the driver’s door placard for your exact size.
What size tires fit a Tacoma without a lift?
Most Tacomas can take tires up to about 31 to 32 inches tall without a lift, depending on wheel offset and trim. A 33-inch tire, such as 285/70R17, usually needs a 2 to 3 inch lift or trimming to avoid rubbing.
Is 265/70R17 a 33-inch tire?
No. A 265/70R17 is about 31.6 inches tall. A true 33-inch tire is closer to 285/70R17, which measures about 32.7 inches, or a 33×10.50R17.
How do I use a Tacoma tire size calculator?
Enter your current tire size and the size you want to compare. The calculator returns the new overall diameter, width, and the speedometer difference. Try to stay within about 3% of stock diameter for the closest factory behavior.
Can I put different size tires on my Tacoma?
Running mismatched sizes is not recommended, especially on a four-wheel-drive Tacoma. Different rolling diameters strain the drivetrain and can cause uneven wear. Replace all four tires together or ask a tire professional for guidance.
Conclusion: Get Your Tacoma Tire Size Right the First Time
The right Tacoma tire size comes down to three steps: confirm what your truck wears now, understand the stock size for your generation and trim, and check any change with a tire size calculator before you buy.
Stay near factory size for the best daily comfort and efficiency. Move to a 31 to 32 inch tire for a modest boost. Choose a 33-inch setup only if you are ready for the lift, clearance, and gearing that come with it. Whatever you pick, match the load rating, rotate regularly, and keep pressure correct.
