What should a driver watch for regarding the rearmost trailer's tires when operating in hot weather over long distances?

Pick an answer

1. Rear trailer tires never overheat regardless of conditions
2. Tire temperature is irrelevant to a trailer's position anywhere in the combination since tire temperature is assumed to depend only on the weather, not on load or position
3. Only the tractor's tires need monitoring in hot weather
4. Signs of overheating, since rear trailer tires can be harder to monitor and may go unnoticed longer than the lead trailer's
