Buying Bigger Tires For Your Toyota Tacoma? Follow This Tire Size Guide
Toyota has used a variety of tire sizes for the Tacoma over the years. Each generation has had factory wheels that just kept getting bigger and bigger. 14 and 15 inch wheels were common on the first gen Tacomas, but the latest fourth generation models start at 17 inches and go up from there.
Yet, for many enthusiasts, factory specifications are just the beginning. This article explores the maximum safe tire sizes, the key fitment rules, and the trade-offs and benefits of deviating from stock dimensions.

Decoding Your Tires: What Do The Numbers Mean?
Before browsing for new sets, you need to understand the alphanumeric string on your tire’s sidewall. Let’s break down a common Gen 4 Tacoma size - 265/70 R17 - into plain English:
265 (Width): This represents the width of the tire in millimeters from one sidewall to the other. A higher number means a wider tire and a larger "footprint" on the road.
70 (Aspect Ratio): This number tells you the height of the sidewall. It is a percentage of the width. Here, the height of the tire wall is 70% of 265mm. A higher sidewall is better for off-roading and ride quality, but worse for on-road handling.
R (Construction): This stands for "Radial," which is the standard design for nearly every modern highway and off-road tire.
17 (Rim Diameter): This is the size of the wheel (in inches) that the tire is built to fit. Larger diameter rims are more eye-catching, but they limit the size of the sidewall height.
Mastering tire measurements is essential for Tacoma owners who want to maximize ground clearance without sacrificing safety.
The Big Question: How Large Of A Tire Will Fit?
One of the simplest mods for your Tacoma is to install larger tires. It's a quick way to improve both the look and capability of your truck. Luckily, the Toyota Tacoma wheel wells have a good amount of room to play with, so you can go up a few sizes without major problems.
But what's the biggest tire a Tacoma can fit? Here are some general guidelines to get you started.
Before you size up, consider these three factors:
Speedometer Accuracy: Your truck’s speedometer and odometer will read lower than reality when the tire size increases. There are software kits to reprogram these systems, and it is recommended you look into them.
Torque Loss: Larger tires look cool, but you will lose low-end torque. You are essentially adding to the overall diameter of your drive wheel, which effectively raises your rear axle gearing. This translates into slower acceleration.
Ride and Handling: Increasing the width and height of your tires will affect ride, handling, and steering feel. Wide tires will make the steering heavy at parking speeds. Larger tires weigh more, so the ride will be slightly worse.
While massive tires offer an aggressive aesthetic, they also increase the rotating mass, which can make your truck feel less responsive during acceleration.

Rules For Fitment
- The 3% Height and Width Rule
Generally, you can increase your tire's height and width by 3% each without having to install a lift or leveling kit. Most tire dealers call this the “plus 1” tire size increase. It is an affordable and reasonable option for a modification without a large expense.
- 1″ Lift Equals 1″ Tire Height
The general rule for lift kits is that you can increase tire height by 1″ for each inch of lift. If you decide to add a 2″ lift, you can increase tire height by 2″. Keep in mind, this DOESN’T apply to width. Adding width is all about buying wider rims with different backspacing.
Oversized Tires Without Requiring A Lift Kit
The recommendations below are based on standard Toyota factory wheel specifications. If you upgrade to aftermarket wheels with custom backspacing, this will allow you to use even wider tires. However, going too wide can strain the suspension, and cause other issues such as rubbing which may require further modifications.
Using the 3% Rule (increasing tire height/width by roughly 3% or ~1 inch), here are the max recommended tire sizes for stock Toyota Tacoma wheels without requiring a lift kit.
Below are the oversized tire recommendations for the 2nd-generation+ Tacomas. First-gen Tacos are still popular with many off-roaders, but most owners prefer aftermarket mods for these trucks, since OEM upgrades were much milder back then.
| Toyota Tacoma Tire Size Upgrades (Gen 2 - Gen 4) | ||||
|---|---|---|---|---|
| Generation | Trim Level | Stock Tire Size | Max Recommended Size | Height Increase (%) |
| Gen 2 (2005-2015) | Base / SR5 (15") | 215/70 R15 | 225/70 R15 | +2.0% |
| Base / SR5 (16") | 245/75 R16 | 255/75 R16 | +2.5% | |

| TRD Pro | 265/70 R18 | 275/70 R18 | +1.8% | |
Leveling Kit Tire Sizes (up to 2" Lift)
Installing a 2-inch lift kit (or a leveling kit) significantly increases wheel-well clearance, allowing you to bypass the strict 3% rule. This modification typically allows for tires in the 32 to 33-inch range, depending on the generation.
| Toyota Tacoma 2" Lift Tire Upgrades (Gen 2 - Gen 4) | ||||
|---|---|---|---|---|
| Generation | Trim Level | Stock Tire Size | Max Size w/ 2" Lift | Height Increase (%) |
| Gen 2 (2005-2015) | Base / SR5 (16") | 245/75 R16 | 265/75 R16 | +3.6% |
| TRD Sport | 265/65 R17 | 275/70 R17 | +5.2% | |
| TRD Off-Road | 265/70 R16 | 265/75 R16 | +3.3% | |
| Limited | 265/60 R18 | 275/65 R18 | +5.2% | |
| Gen 3 (2016-2023) | SR / SR5 | 245/75 R16 | 265/75 R16 | +3.6% |
| TRD Sport | 265/65 R17 | 275/70 R17 | +5.2% | |
| TRD Off-Road | 265/70 R16 | 265/75 R16 | +3.3% | |
| Limited | 265/60 R18 | 275/65 R18 | +5.2% | |
| TRD Pro | 265/70 R16 | 285/75 R16* | +7.2% | |
| Gen 4 (2024+) | SR / SR5 | 245/70 R17 | 285/70 R17 | +7.2% |
| TRD Off-Road | 265/70 R17 | 285/70 R17 | +3.5% | |
| Sport / Limited | 265/65 R18 | 285/65 R18 | +3.2% | |
| TRD Pro | 265/70 R18 | 285/75 R18 | +6.7% | |
Note: While a 2" lift provides vertical clearance, widths over 275mm on Gen 2 and Gen 3 Tacomas often require aftermarket wheels with different offsets or wheel spacers to clear the Upper Control Arms (UCA).
Because the 4th Gen Tacoma has better fender clearance than previous generations, a 2-inch lift allows for 33-inch or even some 34-inch tires with minimal to no trimming.
3" Lifts
If you are wondering why there are a lot of 2" lift options for Tacomas, but very few taller lifts available, there are a lot of good reasons: The downsides of 3" lifts:
Premature Wheel Bearing Failure: The combination of heavy tires and the aggressive offset required to fit them puts immense leverage on the front wheel bearings, leading to frequent and expensive replacements.
Permanent Modification: To clear 35-inch (315mm) tires, you often need to trim the front cab mount. This can lead to corrosion issues, and the truck may not pass a safety inspection.
Drivetrain Strain: Your stock CV axles will operate at the extremes of their intended angle range, causing them to wear out faster. Additionally, the needle bearing in the front differential that supports the inner CV shaft can cause vibrations because the axle is running at angles it wasn't designed for.
Compromised Ride Quality: 3" lifts max out the angles of your control arms, making it impossible to get a correct alignment with stock control arms, resulting in vague steering feel on the highway, and uneven tire wear.
Choose Genuine TRD Wheels
If you’re ready to upgrade your Tacoma with a set of new tires, give it an even sharper look with a set of OEM TRD or TRD Pro wheels. Generic aftermarket rims don’t undergo the rigorous testing that TRD wheels do, so there is no telling how they will fit and perform over time.
Buying genuine Toyota wheels online is far more affordable than you might think, and not only do you get the best quality and performance, every OEM part we sell is backed by a comprehensive warranty. Check out our TRD Pro Wheels FAQs for more information and contact us to order your wheels today.
