Factory tire sizes by wheel diameter

How to verify your exact tire size

Use these steps to confirm the tire size on your Ram 1500, especially if you’re shopping for replacements or considering wheel changes.

1. Check the driver-side door jamb placard for the "Original Equipment" tire size and inflation pressures; it lists the recommended size for your truck’s configuration.


2. Inspect the sidewall of your current tires; the size is printed in a format such as P245/70R17, which you can match when shopping for replacements.


3. If you don’t have the placard or manual, consult the owner's manual or a dealership or Mopar parts catalog to confirm compatible sizes and load/speed ratings for your trim.

Note: If you plan to use aftermarket wheels or change sizes, you may need to consider clearance, suspension, and load requirements. A tire professional can help ensure proper fitment.
