The data plate on your telehandler specifies a tire pressure of 90 psi (620 kPa). You are operating in a cold Canadian winter environment where temperatures can significantly drop. How does temperature affect tire pressure, and what adjustment, if any, should you consider during your pre-operation check?

Question: The data plate on your telehandler specifies a tire pressure of 90 psi (620 kPa). You are operating in a cold Canadian winter environment where temperatures can significantly drop. How does temperature affect tire pressure, and what adjustment, if any, should you consider during your pre-operation check?

Answer options:

• Cold temperatures cause tire pressure to increase, so you should slightly decrease the pressure. ✅ Cold temperatures cause tire pressure to decrease; ensure tires are inflated to the recommended 620 kPa when cold.
• Temperature has no significant effect on tire pressure; maintain 620 kPa regardless of ambient conditions.
• Cold temperatures cause tire pressure to decrease; overinflate by 10% to compensate.

Correct answer: Cold temperatures cause tire pressure to decrease; ensure tires are inflated to the recommended 620 kPa when cold.

Explanation: Tire pressure drops approximately 1 psi (7 kPa) for every 5.5°C decrease in temperature. Therefore, in cold weather, it's crucial to inflate tires to the recommended pressure when they are cold to ensure adequate pressure during operation, as per tire manufacturer guidance.
