Tire Sizes by Trim

The 2019 Chevrolet Silverado 2500HD was offered with several tire and wheel combinations across its various trims. Always check your vehicle's door jamb placard for the most accurate information for your specific truck.

Note: Specific pressures can vary based on the exact tire and configuration. Always refer to your vehicle's door placard.

Recommended Replacement Tires

When it comes to replacing tires on your 2019 Chevrolet Silverado 2500HD, you'll want to prioritize tires designed for heavy-duty truck use, offering excellent load-carrying capacity, durability, and traction. Look for tires with an E-load range (10-ply equivalent) and appropriate load index.

• BFGoodrich All-Terrain T/A KO2 (Premium Price Tier): A favorite among truck owners for its aggressive all-terrain capability, long tread life, and strong sidewalls. Excellent for those who frequent off-road conditions or tow heavy loads.
• Michelin Defender LTX M/S (Premium Price Tier): Known for its exceptional highway comfort, quiet ride, long-lasting tread, and all-season traction. A great choice for trucks that spend most of their time on pavement but still need robust performance.
• Cooper Discoverer AT3 XLT (Mid Price Tier): This tire offers a good balance of aggressive all-terrain looks, comfortable on-road manners, and strong durability. It's a solid option for mixed use and towing.
• Firestone Transforce AT2 (Mid Price Tier): Often an OEM choice, the Transforce AT2 is a reliable commercial-grade tire designed for durability and stability under heavy loads. Good for work trucks.

When to Inflate to Max Load PSI

For heavy-duty trucks like the 2019 Chevrolet Silverado 2500HD, tire pressure is critical and often needs to be adjusted based on the load carried. Your door placard will list the recommended cold tire pressure for light-load conditions and sometimes a higher pressure for maximum load.

Always maintain the tire pressure recommended on your door placard. However, when you are towing or hauling heavy loads approaching your truck's Gross Vehicle Weight Rating (GVWR) or Gross Combined Weight Rating (GCWR), it is often necessary and recommended to inflate your tires to the maximum cold inflation pressure embossed on the tire's sidewall (or as specified for maximum load on your door placard, if present). This ensures the tires can safely support the increased weight, prevents excessive sidewall flex, and reduces heat buildup, which can lead to tire failure. Driving with underinflated tires under heavy load is extremely dangerous.

It's also crucial to remember to reduce the tire pressure back to the recommended light-load pressure (from the door placard) when the truck is unloaded for everyday driving. Over-inflation when not carrying a load can lead to a harsher ride, uneven tire wear, and reduced traction.

Lug Nut Torque & Pattern

Properly torquing your lug nuts is essential for wheel retention and safety. For the 2019 Chevrolet Silverado 2500HD, the recommended lug nut torque is typically 140-150 lb-ft (190-203 Nm). Always use a torque wrench to ensure accurate tightening.

When tightening, follow a star pattern to ensure the wheel is seated evenly against the hub. This helps prevent warping of the rotor or wheel. For an 8-lug wheel:

1. Start with one lug nut.
2. Move directly across to the opposite lug nut.
3. Continue this pattern, skipping lug nuts to create a star or crisscross pattern until all nuts are snug.
4. Once all are snug, go around again in the star pattern to torque each lug nut to the full specification.

Common Tire Issues for This Vehicle

Owners of 2019 Chevrolet Silverado 2500HDs, like many heavy-duty truck owners, may encounter specific tire-related issues:

• Rapid/Uneven Tire Wear: This can often be attributed to improper tire inflation (under or over-inflation), misaligned suspension, or an imbalanced tire. Given the truck's heavy-duty nature, maintaining correct pressures for the load is crucial.
• Cupping or Feathering: Often a symptom of worn suspension components (shocks, ball joints), imbalance, or improper rotation. This appears as uneven wear patterns across the tread.
• TPMS Sensor Issues: While generally reliable, TPMS sensors can occasionally malfunction due to battery depletion (they typically last 5-10 years), physical damage, or interference. The 2019 Silverado 2500HD uses 315 MHz sensors.
• Hydroplaning with Worn Tires: As with any vehicle, worn tire tread significantly reduces a tire's ability to channel water, increasing the risk of hydroplaning in wet conditions. Heavy trucks can be particularly susceptible due to their weight.

Regular tire rotations (every 5,000-7,500 miles), proper inflation maintenance based on load, and periodic alignment checks are the best ways to prevent most of these issues.
