What size tires can I fit on my stock RAM 1500?

The stock tires on your RAM 1500 can typically be upgraded to larger sizes, providing a more aggressive look and improved off-road capabilities. However, the maximum tire size you can fit will depend on various factors, including your specific model year, trim level, and any modifications made to the vehicle.


Determining the Maximum Tire Size


To determine the maximum tire size you can fit on your RAM 1500, you'll need to consider the following factors:



  • Wheel Well Clearance: The available space in the wheel well is a critical factor, as larger tires need to fit without rubbing against the fender or suspension components. Measure the clearance between the existing tires and the wheel well to estimate the maximum size you can accommodate.

  • Lift Kit or Suspension Modifications: If your RAM 1500 has a lift kit or other suspension modifications, it may allow for larger tires to be installed without rubbing. Consult with the manufacturer or a professional installer to determine the maximum tire size for your specific setup.

  • Speedometer and Odometer Accuracy: Larger tires can affect the accuracy of your vehicle's speedometer and odometer. You may need to recalibrate these systems or install a tire size correction module to ensure accurate readings.


Generally, most stock RAM 1500 models can accommodate tires up to 35 inches in diameter without major modifications. However, it's always best to consult with a professional or refer to your vehicle's owner's manual for the specific recommendations.


Tire Installation Considerations


Once you've determined the maximum tire size, there are a few additional factors to consider when installing larger tires on your RAM 1500:



  • Wheel Compatibility: Ensure that the new tires are compatible with your existing wheels or that you purchase new wheels that are the correct size and offset for your vehicle.

  • Brake Clearance: Larger tires may require modifications to the brake system to ensure adequate clearance and proper functioning.

  • Fender Trimming: Depending on the tire size, you may need to trim the fenders or install fender flares to accommodate the larger tires without rubbing.

  • Gearing and Drivetrain Modifications: Larger tires can affect the gearing and performance of your RAM 1500. You may need to consider gear ratio changes or other drivetrain modifications to maintain optimal performance.


It's important to have any tire upgrades installed by a qualified professional to ensure the safety and proper functioning of your vehicle.
