What is the biggest tire I can put on my 2017 F350?

The biggest tire you can put on your 2017 Ford F350 depends on several factors, including the vehicle's suspension, wheel well clearance, and overall dimensions. While there are no one-size-fits-all solutions, we'll explore the key considerations to help you determine the largest tire size that will safely and effectively fit your truck.


Factors to Consider


When upgrading the tires on your 2017 F350, you'll need to take the following into account:



  • Wheel Well Clearance: The amount of space between the tire and the wheel well is crucial. You'll need to ensure the larger tires don't rub against the fenders or suspension components, which could cause damage.

  • Suspension Modifications: Lifting the suspension or using a leveling kit can provide additional clearance for larger tires. However, these modifications may also affect the vehicle's handling and performance.

  • Tire Width: Wider tires can provide better traction and off-road capability, but they may also require fender flares or other modifications to prevent rubbing.

  • Tire Diameter: Increasing the tire diameter can improve ground clearance, but it can also affect the speedometer and odometer readings, as well as the vehicle's gearing and fuel efficiency.


It's important to carefully research and consider these factors to ensure the largest tire size you choose is compatible with your 2017 F350 and won't compromise its safety or performance.


Recommended Tire Sizes


Based on the typical specifications of a 2017 Ford F350, the largest tire size you can safely install without major modifications is typically a 37-inch tire. This size provides a good balance of off-road capability, ground clearance, and minimal impact on the vehicle's handling and performance.


However, it's important to note that the specific tire size that will fit your F350 may vary depending on the exact model, trim level, and any existing modifications. It's always best to consult with a professional tire and wheel specialist or your local Ford dealer to determine the maximum tire size that will work for your vehicle.


Remember, safety should be your top priority when upgrading the tires on your 2017 F350. Carefully consider the recommendations and ensure the larger tires you choose will not compromise the vehicle's handling, stability, or braking performance.
