Tire Sizes by Trim

Note: The Power Wagon trim typically uses a smaller 17-inch wheel with a larger aspect ratio tire for off-road capability. Always verify your specific vehicle's door placard for accurate information.

Recommended Replacement Tires

When it's time to replace the tires on your 2019 Ram 2500, especially being a heavy-duty truck, selecting the right tire is crucial for safety, performance, and longevity. You'll want to focus on Light Truck (LT) tires with an appropriate load range (typically E for these trucks) to handle the vehicle's weight and towing/hauling capabilities.

• BFGoodrich All-Terrain T/A KO2: (Premium Price Tier) A highly popular all-terrain tire known for its durability, excellent off-road traction, and respectable on-road manners. Great for owners who frequently venture off paved roads or experience varying weather conditions.
• Michelin Defender LTX M/S: (Premium Price Tier) This highway-terrain tire offers exceptional longevity, a comfortable and quiet ride, and excellent wet and dry traction. An ideal choice for truck owners who spend most of their time on highways and want a reliable, long-lasting tire.
• Falken Wildpeak A/T3W: (Mid-Range Price Tier) A fantastic all-around tire that balances aggressive off-road capability with good on-road performance. It offers strong wear resistance and a competitive price, making it a popular choice for many heavy-duty truck owners.
• Goodyear Wrangler Duratrac: (Premium Price Tier) This tire is a hybrid between an all-terrain and mud-terrain, offering aggressive traction for demanding conditions while still being serviceable on the highway. Ideal for those who need serious off-road capability.

When to Inflate to Max Load PSI

For heavy-duty trucks like the 2019 Ram 2500, understanding tire pressure beyond the door placard recommendation is important, especially when towing or hauling. Your door placard provides the minimum recommended cold tire pressure for various loading conditions up to the vehicle's Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR).

You should consider inflating your tires to the maximum PSI indicated on the tire's sidewall (the "Max. Press." value) only when your truck is loaded to or near its maximum payload or towing capacity.

This higher pressure helps the tire maintain its proper shape and contact patch under extreme loads, preventing excessive sidewall flex, reducing heat buildup, and distributing the weight more evenly. Running max load PSI when lightly loaded, however, will result in a harsher ride, increased tire wear in the center of the tread, and can negatively affect handling.
