Question: In extreme cold weather conditions (e.g., below -25°C), what is a key operational hazard specific to the wheel loader's tires that requires particular attention?

Answer options:

• Increased tire pressure due to thermal expansion of air. ✅ Reduced tire flexibility and potential for cracking or sudden deflation, especially if under-inflated or damaged.
• Enhanced traction on icy surfaces due to changes in rubber compound properties.
• Faster wear and tear of tire tread from colder asphalt.

Correct answer: Reduced tire flexibility and potential for cracking or sudden deflation, especially if under-inflated or damaged.

Explanation: Rubber compounds in tires become significantly stiffer and lose flexibility in extremely cold temperatures. This makes tires more susceptible to cracking, especially in the sidewalls or tread, and increases the risk of punctures or sudden deflation if they hit obstacles or are damaged, a critical consideration in cold weather operations.
