What Tire Size Does the 2020 Ram Rebel Use?
The standard factory tire size for the 2020 Ram Rebel is 275/70R18. This specification is designed to balance off-road capability with on-road comfort and efficiency for the specific Rebel trim level.
- Standard factory size: 275/70R18.
- Common upgrade: 33-inch tires.
- Consider suspension for larger sizes.
- Tire width affects handling.
Understanding your truck's tire size is fundamental to maximizing its performance and ensuring safe operation. For the 2020 Ram Rebel, the factory-fitted 275/70R18 tires provide a solid foundation. This designation breaks down as follows: 275 millimeters is the tire's width, 70 is the aspect ratio (sidewall height as a percentage of width), R signifies radial construction, and 18 is the wheel diameter in inches.
This specific dimension is crucial because it dictates ground clearance, load-carrying capacity, and how the vehicle's speedometer and odometer register distance. Deviating significantly from the factory size without proper calibration can lead to inaccuracies and potential mechanical stress.
Factory Tire Specifications
The 2020 Ram Rebel typically comes equipped with all-terrain (AT) tires in the 275/70R18 size. These tires feature a tread pattern optimized for grip on varied surfaces, from paved roads to light trails and gravel. Their construction offers a good compromise for daily driving, offering reasonable noise levels and fuel economy while providing the durability needed for off-pavement excursions.
It is imperative to acknowledge that tire manufacturers may offer slightly different tread designs or load ratings within the same size specification. Always verify the load index and speed rating on the tire sidewall to ensure it meets or exceeds your vehicle's requirements.
The 275/70R18 size offers an excellent blend of factory performance and everyday usability.
Why Tire Size Matters for Your 2020 Ram Rebel
Why should you pay close attention to the 275/70R18 dimension or potential changes?
The tire size directly influences your 2020 Ram Rebel's ground clearance, which is paramount for tackling obstacles off-road. A larger diameter tire lifts the vehicle, allowing it to clear rocks, logs, and uneven terrain more easily. This increased height also improves the approach, departure, and breakover angles, crucial for challenging trails.
Beyond off-road prowess, tire size impacts your truck's on-road behavior. Wider tires, often chosen during upgrades, can improve cornering stability and traction on dry pavement. However, they may also increase rolling resistance, potentially reducing fuel economy and introducing more road noise. Understanding this mechanism is fundamental.
Choosing the right tire size is a strategic decision impacting your Ram Rebel's performance across all terrains.
Furthermore, the overall diameter of the tire affects the gearing. Larger tires effectively make your final drive ratio taller, meaning the engine works less to turn them at a given speed. While this can improve highway MPG, it reduces acceleration and towing capability. Conversely, smaller tires can enhance acceleration but may reduce highway efficiency.
Ensure any tire upgrade is compatible with your Ram Rebel's anti-lock braking system (ABS) and electronic stability control (ESC) sensors. Incorrect tire sizes can interfere with these safety systems.
The right tire size directly translates to enhanced off-road capability and optimized on-road handling.
Choosing and Upgrading Your Ram Rebel Tires
When considering upgrades beyond the factory 275/70R18, several popular alternatives emerge for the 2020 Ram Rebel. The most common path involves increasing tire diameter, often to 33-inch or 35-inch tires.
Common Upgrade Paths
A popular upgrade is moving to a 33-inch tire, such as 285/70R17 or 285/75R17 if you switch to 17-inch wheels, or a 295/65R18 on 18-inch wheels. These sizes offer a noticeable increase in ground clearance and a more aggressive stance without typically requiring extensive modifications. They provide a significant boost in off-road capability while remaining manageable for daily driving.
For more extreme off-road use, 35-inch tires like 315/70R17 or 325/65R18 become an option. However, fitting 35-inch tires on a 2020 Ram Rebel often necessitates a lift kit (typically 2-3 inches) and potentially fender trimming or aftermarket fender flares to prevent rubbing during articulation.
When upgrading tire size, always factor in the weight difference. Heavier tires can strain suspension components and affect braking performance. Select tires that balance size with appropriate weight for your intended use.
Considerations for Larger Tires
Switching to a significantly larger tire size, like those approaching 33 inches or more, requires careful consideration. You need to ensure adequate clearance not just at static ride height but also when the suspension compresses or turns. A suspension lift kit is often necessary to accommodate these larger diameters. Additionally, recalibrating your speedometer and odometer is essential; many modern trucks allow this through onboard computer systems or diagnostic tools.
It is crucial to verify tire compatibility and potential rubbing issues before committing to a new size.
