When to inflate to max load psi

For a heavy-duty vehicle like the Ram ProMaster, understanding when to inflate your tires to the maximum recommended PSI (often listed on the tire's sidewall) is critical for safety and tire longevity. The door placard provides the recommended cold tire pressure for typical operating conditions and loads.

However, if you are consistently carrying maximum or near-maximum payloads, or towing heavy loads, you may need to increase your tire pressure closer to the maximum cold inflation pressure indicated on the tire's sidewall. This ensures the tire can safely support the additional weight without overheating or experiencing premature wear on the shoulders.

Always follow these guidelines:

• Refer to your vehicle's door placard first for standard operating pressures.
• Consult your owner's manual for specific recommendations on tire pressure adjustments for heavy loads.
• Never exceed the maximum cold inflation pressure stamped on the tire's sidewall, regardless of the load.
• Check tire pressures when tires are cold (driven less than a mile).

Under-inflation with heavy loads can lead to tire failure, poor handling, and reduced fuel economy.

Lug nut torque & pattern

Proper lug nut torque is essential for preventing wheels from coming loose and ensuring even clamping force. For the 2025 Ram ProMaster, the recommended lug nut torque specification is typically 130-140 ft-lbs (176-190 Nm).

Always use a torque wrench to ensure accurate tightening. The lug nuts should be tightened in a star pattern (also known as a criss-cross pattern) to ensure the wheel is seated properly and evenly against the hub. After driving for about 50-100 miles after a wheel removal or rotation, it
