    Recommended Replacement Tires

    When it comes to a heavy-duty truck like the 2024 Ram 3500, choosing the right replacement tires is crucial for safety, performance, and longevity. Here are a few popular options across different price tiers, known for their durability and towing/hauling capabilities:

    • Premium Option: Michelin Defender LTX M/S (Around $300-$400 per tire)
      • Renowned for excellent all-season traction, long tread life, and a comfortable/quiet ride. A top choice for those who prioritize reliability and performance.
    • Mid-Range Option: Cooper Discoverer AT3 XLT (Around $250-$350 per tire)
      • A versatile all-terrain tire offering a good balance of off-road capability and on-road manners. Features a durable tread compound and a stout construction, ideal for trucks that see a mix of highway and light-duty off-road use.
    • Value Option: Firestone Transforce HT2 (Around $200-$300 per tire)
      • A workhorse highway-terrain tire designed for year-round performance and heavy-duty hauling. Offers good wet and dry traction and robust construction for enduring heavy loads.

    When to Inflate to Max Load PSI

    For heavy-duty trucks like the 2024 Ram 3500, understanding tire pressure is critical, especially when hauling or towing. The "recommended cold tire pressure" listed on your door jamb placard is generally for an unloaded or lightly loaded vehicle.

    You should inflate your tires to the maximum load psi (which can often be found on the tire’s sidewall) only when:

    • You are consistently carrying or towing near the maximum Gross Vehicle Weight Rating (GVWR) or Gross Combined Weight Rating (GCWR) of your truck. This ensures the tires can safely support the increased load, prevent excessive heat buildup, and maintain stable handling.
    • You are preparing for a long trip with a heavy load. Increased pressure helps distribute the weight more effectively across the tire
