What is the condition that must be verified between the tires?

The requirement for verifying the condition between the tires is that they must not be touching and have no debris. This ensures that there is sufficient clearance between the tires to prevent any potential friction or damage during vehicle operation. Having a space between the tires allows for proper air circulation, which can help maintain optimal tire temperature and performance.

In addition, ensuring that there is no debris between the tires is crucial for safety. Debris can cause interference, which might lead to uneven tire wear or even a blowout, ultimately risking the safety of the vehicle and its occupants. Therefore, confirming that there is neither contact nor debris between the tires is essential as part of a thorough pre-trip inspection.
