Commercial motor vehicle tires experience rapid heat buildup and increased internal pressure during high-temperature highway operations. To prevent catastrophic tire failure, drivers must follow a systematic procedure during en-route stops. In what chronological sequence should a driver execute this hot-weather tire inspection procedure?
- 1Pull the commercial vehicle into a safe parking location upon reaching the required driving interval of every 2 hours or 100 miles.
- 2Conduct a visual examination of all tire treads and sidewalls to check for cuts, bulges, or signs of tread separation.
- 3Check tire inflation pressure with an accurate gauge, ensuring no air pressure is bled off to reduce hot pressure readings.
- 4Remain stationary in the parking area to let any excessively hot tire cool down naturally before resuming the trip.
Answer
The driver should first stop safely at the 2-hour or 100-mile interval, visually inspect all tires for physical defects, check tire pressures without bleeding air, and finally remain parked to allow any overheated tire to cool down completely before continuing travel.
The correct sequence starts with stopping at the designated 2-hour or 100-mile interval, followed by visual inspection of tire casings, verifying pressures without bleeding air, and waiting for overheated tires to cool down naturally prior to resuming travel.
