Selecting the correct 2017 Ram 2500 tire size is fundamental to ensuring the truck performs as intended, whether the task involves towing a heavy fifth wheel across the country or navigating daily commutes on suburban streets. The 2017 model year offered a versatile range of wheel and tire combinations, primarily utilizing a 20-inch diameter setup that balanced on-road comfort with off-road durability. Understanding the specific load index, speed rating, and overall diameter for your configuration is crucial for maintaining the vehicle's factory safety standards and ride characteristics.
Factory Specifications and Common Fitments
The baseline 2017 Ram 2500, often equipped with standard all-season tires, typically rolled on 20-inch diameter wheels with a size such as P275/65R20. This measurement indicates a tire with a cross-section width of 275 millimeters, an aspect ratio of 65% (the sidewall height is 65% of the width), mounted on a 20-inch rim. For drivers who opted for the RamBox cargo management system or higher trims, the tire package frequently upgraded to a P285/55R20 configuration, which offers a wider footprint for improved traction while slightly reducing the sidewall height for a more responsive handling feel.
Decoding the Tire Sidewall Information
Reading the information molded into the sidewall of your existing tires is the fastest way to determine the correct 2017 Ram 2500 tire size replacement. Look for a sequence beginning with a "P" for passenger car tires, followed by the width, aspect ratio, and construction type denoted by an "R" for radial. The final number indicates the wheel diameter in inches. It is essential to match these specifications exactly; installing a tire that is too wide or has an incorrect diameter can trigger warning lights, affect the accuracy of the speedometer, and place undue stress on the wheel bearings and suspension components.
Performance Tires vs. All-Season Tires
When comparing performance tires to all-season tires for the 2017 Ram 2500, the choice largely depends on driving habits and climate. Performance tires often feature a wider tread pattern and softer rubber compound, providing superior grip during spirited driving or in warm weather conditions. However, they tend to wear more quickly and generate more road noise. All-season tires, conversely, offer a quieter ride and longer tread life, making them a practical choice for daily drivers who encounter snow, rain, and dry pavement throughout the year.
The Importance of Load Range and Rating
Because the Ram 2500 is a heavy-duty truck, the load range of the tire is a critical specification that should never be overlooked. Tires designed for this truck often feature a "D" or "E" load range, which corresponds to the number of plies used in the construction and directly correlates to the tire's ability to handle heavy payloads and towing stress. Installing a lower load range tire than specified can lead to excessive flexing, overheating, and a significantly reduced tire life, particularly when the truck is fully loaded with cargo or towing a trailer.
Adjusting for Larger Diameter Wheels
Enlarging the wheel diameter beyond the factory standard is a popular modification for owners seeking an aggressive stance or improved off-road capability. If you choose to install 22-inch or 24-inch wheels, selecting the correct 2017 Ram 2500 tire size becomes a matter of calculating the overall diameter to avoid issues with the vehicle's computer system. Increasing the diameter by more than 3% can cause the vehicle stability control and anti-lock braking system to misinterpret wheel speed, potentially triggering traction control malfunctions or inaccurate odometer readings.
