A loader operator is checking the tire pressures as part of their weekly preventive maintenance schedule. They find that one of the drive tires on a large wheel loader is 70 kPa (10 psi) below the manufacturer's recommended cold inflation pressure, while the other three tires are within specification. What steps should the operator take?

Question: A loader operator is checking the tire pressures as part of their weekly preventive maintenance schedule. They find that one of the drive tires on a large wheel loader is 70 kPa (10 psi) below the manufacturer's recommended cold inflation pressure, while the other three tires are within specification. What steps should the operator take?

Answer options:

• Inflate the low tire to the specified pressure and continue with normal operations, rechecking pressure in a few days. ✅ Inflate the low tire to the specified pressure, closely inspect the tire for any punctures or damage, and report any findings to maintenance.
• Inflate the low tire to approximately 35 kPa (5 psi) above the specified pressure to account for potential slow leaks.
• Immediately remove the loader from service and notify maintenance to replace the tire, as low pressure indicates a critical failure.

Correct answer: Inflate the low tire to the specified pressure, closely inspect the tire for any punctures or damage, and report any findings to maintenance.

Explanation: While it's important to inflate the tire to the correct pressure, a significant unexplainable pressure drop warrants further investigation for damage or leaks. Simply topping up without inspection might lead to repeated pressure loss and potential tire failure, while immediately removing the loader from service without inspection might be an overreaction. Over-inflating the tire is also incorrect and can lead to uneven wear and potential safety hazards.
