When performing a tire pressure check on a wheel dozer, you find one tire is at 300 kPa, while the recommended pressure is 450 kPa. The other tires are within 10 kPa of the recommended pressure. What is the most appropriate action?

Question: When performing a tire pressure check on a wheel dozer, you find one tire is at 300 kPa, while the recommended pressure is 450 kPa. The other tires are within 10 kPa of the recommended pressure. What is the most appropriate action?

Answer options: ✅ Inflate the underinflated tire to the recommended 450 kPa before operation.

• Adjust all other tires to 300 kPa for uniform traction.
• Operate the equipment, but avoid heavy loads and sharp turns.
• Report the discrepancy and continue operating; the difference is not critical.

Correct answer: Inflate the underinflated tire to the recommended 450 kPa before operation.

Explanation: Underinflated tires lead to increased rolling resistance, excessive heat buildup, premature wear, and instability, and can negatively affect steering and braking. CSA B335 and OPSWA guidelines require tires to be at the manufacturer's recommended pressure for safe operation and optimal performance.
