Whats the biggest size tire I can put on my Ford F-150?

The biggest size tire you can put on your Ford F-150 depends on several factors, including your vehicle's year, model, and trim level. Generally, you can fit tires up to 35 inches in diameter on a stock F-150, but the exact size may vary. Let's explore the details and guidelines for upgrading your F-150's tires.

Factors to Consider

When determining the maximum tire size for your Ford F-150, you'll need to take into account the following factors:

• Wheel Well Clearance: The amount of space between the tire and the wheel well is a critical consideration. Larger tires may rub against the fender or suspension components, causing damage or interference.


• Lift Kit: If your F-150 is equipped with a lift kit, it may allow for larger tires to be installed without rubbing issues.


• Trim Level: Different F-150 trim levels may have varying factory tire sizes and wheel well clearances, affecting the maximum tire size you can fit.


• Suspension Modifications: Upgrading your F-150's suspension components, such as shocks or control arms, can also impact the maximum tire size you can accommodate.

It's important to carefully measure your wheel well clearance and consult your vehicle's specifications to determine the largest tire size that will fit without causing any interference or rubbing issues.

Recommended Tire Sizes

According to the information gathered from various sources, here are some general guidelines for the maximum tire size you can install on a Ford F-150:

• Stock F-150: Up to 35-inch tires can typically be fitted on a stock F-150 without major modifications.


• F-150 with Lift Kit: With a 2-4 inch lift kit, you may be able to accommodate tires up to 37 inches in diameter. web>


• F-150 Raptor: The high-performance Raptor model can handle tires up to 37 inches in diameter without any modifications. web>

It's important to note that these are general guidelines, and the actual maximum tire size may vary depending on your specific F-150 model, year, and any modifications you've made. Always consult with a professional tire and wheel specialist to ensure the largest tire size that can be safely installed on your vehicle.

What are the biggest tires I can put on my truck without a lift?

Understanding proper wheel tire fitment is essential here, since it ensures your new tires match your rims and vehicle setup. On average, if your truck isn't lifted, you can fit tires up to 33”.

Will 33s fit on a stock F-150?

Yes, 33-inch tires will generally fit on a stock F-150, though some rubbing may occur, especially with more aggressive or wider tires, and it depends on the specific F-150 model and wheel offset. Many stock F-150s come with tires that are already very close to 33 inches in diameter. For the best fit without modifications, a 33x11.5 tire on an 18x9 wheel with a zero or slight positive offset is often recommended.

Things to consider

• Tire size and width: A 33-inch tire with a narrower width like 11.5 inches is more likely to fit without rubbing than a wider 33x12.50 tire. 
• Wheel offset: A positive or zero offset will keep the tire more tucked in and reduce the chance of rubbing. A negative offset will push the tire out further and increase the likelihood of rubbing, potentially requiring modifications like cutting crash bars. 
• Minor rubbing: Even with a good fit, you might experience some minor rubbing on the plastic part of the fender liner, particularly when turning sharply in reverse. 
• Vehicle model year: Modern F-150s (2015-present) have more clearance. Some 2021 models even come with 33-inch tires from the factory. 
• Potential for modifications: If you encounter rubbing, it's often easily resolved by trimming the plastic fender liner. For more significant rubbing, a 1.5-inch or 2-inch leveling kit may be needed.

How to choose

• For minimal effort: Opt for a 33x11.5 inch tire on a stock or slight positive offset wheel to minimize the need for modifications. 
• For a more aggressive look: If you want a wider tire like a 33x12.50, be prepared to trim the plastic fender liner. 
• To be safe: Consult with a tire professional who can confirm what will fit best on your specific F-150 year and trim level before making a purchase. 

Will 35 tires fit on a stock F-150?

No, 35-inch tires will not fit on a stock F-150 without rubbing, but they can fit with a leveling kit (around 2.52.52.5 inches) and some modifications. Fitting 35-inch tires on a stock F-150 is not possible without rubbing, as the stock suspension and wheel wells are too small. To fit 35-inch tires without rubbing, you typically need to lift the front of the truck with a 2.52.52.5-inch leveling kit and potentially make minor adjustments like trimming or adjusting crash bars.

Why they don't fit on a stock F-150

• Rubbing: Tires will rub against the crash bars (in newer models) and the upper control arm, especially when turning. 
• Limited clearance: The factory F-150 is designed for tires around 31-32 inches in diameter. 

How to make 35-inch tires fit

• Leveling kit: Install a 2.52.52.5-inch leveling kit to raise the front of the truck and provide the necessary clearance. 
• Tire width: Opt for a narrower 35-inch tire, such as a 295295295 width (11.511.511.5 inches) instead of a 12.512.512.5-inch width, to minimize rubbing on the control arm. 
• Crash bars: On newer F-150s, you may need to trim or modify the front crash bars to prevent rubbing. 
• Stock wheels: Using stock wheels with a positive offset (like the factory +44positive 44+44 offset) will help prevent rubbing compared to aftermarket wheels with a more aggressive or negative offset.

What is the biggest tire you can fit on a stock F-150?

The biggest tires you can fit on a stock F-150 without any modifications are typically around 33 inches in diameter, such as a 33x11.5 or 285/70R18, which can fit on 18" or 20" wheels. For some models, a larger 35-inch tire may fit on stock wheels with the factory offset, but larger tires will likely cause rubbing issues with suspension or the front bumper. Fitting 35-inch tires usually requires at least a 2.5-inch lift or leveling kit.
 
For stock F-150s with no modifications

• 33-inch tires: A popular and common fit is a 33x11.5 inch tire, like on an 18x9-inch wheel with a zero offset, which is unlikely to cause rubbing issues on the front bumper or suspension components. 
• Tire size examples:
  • 285/70R18 
  • 275/70R18 

For stock wheels (factory offset)

• Some 2021 F-150 models with stock wheels and factory offset can fit a 34.5x12.5 tire or a 285/75R20 (a 35x11.5 inch tire), but this is often a tight fit and depends on the wheel offset.
• Maintaining a stock offset is key to preventing rubbing. 

For stock F-150s with a lift or leveling kit 

• 35-inch tires: A 2.5-inch lift or leveling kit is often the minimum recommended modification to fit 35-inch tires without rubbing. 
• Other modifications: To fit larger tires (over 35 inches) and maintain proper function, you may need to adjust or replace other suspension components.
