What is the stock tire size on a RAM 1500?
The standard tire size for a Ram 1500 pickup truck is 275/65R18. This tire size provides a balance of performance, comfort, and fuel efficiency for the Ram 1500's intended use as a versatile, full-size truck.
Understanding the Ram 1500 Tire Size Specification
The tire size specification for the Ram 1500 is broken down as follows:
- 275 - This is the tire's width in millimeters.
- 65 - This is the aspect ratio, which is the ratio of the tire's sidewall height to the tread width. A 65 aspect ratio means the sidewall height is 65% of the tread width.
- R - This indicates the tire has a radial construction, which is the most common type of tire construction today.
- 18 - This is the wheel diameter in inches that the tire is designed to fit.
The 275/65R18 tire size is the standard configuration for the base model Ram 1500, though higher trim levels may come equipped with larger 20-inch or 22-inch wheels and tires.
Factors Influencing Ram 1500 Tire Size
The 275/65R18 tire size was chosen by Ram engineers to provide a good balance of attributes for the Ram 1500:
- Ride Comfort: The 65 aspect ratio provides a taller sidewall that helps absorb bumps and provide a smooth, comfortable ride.
- Traction and Capability: The 275 mm width gives the tires good grip and off-road capability, important for a full-size truck.
- Fuel Efficiency: The 18-inch wheel diameter is smaller than optional 20-inch or 22-inch wheels, which helps reduce rolling resistance and improve fuel economy.
Ultimately, the standard 275/65R18 tire size is well-suited for the Ram 1500's intended use as a versatile, capable, and efficient full-size pickup truck.
