Tire inspections

A useful tire observation identifies the physical tire and where it was fitted when the reading was taken. Tire Inspector records its serial, inspection date, position and tread depth in thirty-seconds of an inch. The observation stays with its organization and parent load so the maintenance discussion has an operating context. Use the load assignment to confirm the vehicle actually inspected, especially when dispatch has substituted equipment.

An earlier reading remains useful after a rotation. Keep the previous observation and add the later dated observation for the same serial. A changed position should be explainable from the maintenance evidence. Do not replace yesterday’s position merely to make every historical entry show where the tire is today.

• Identify the tire. Use the serial visible on the tire and the agreed position vocabulary. Resolve an unreadable or disputed identity with Fleet Coordinator before requesting a decision about that tire.
• Record the observation. Enter the measured depth and actual inspection date while the inspection is Draft. An absent reading should stay absent until the inspector can obtain it; entering zero would communicate a different condition.
• Submit the reviewed record. Check the parent load, organization and supporting files before moving to Submitted. Maintenance Reviewer needs the exact observation being considered for rotation or replacement.

Agree how the team writes axle and wheel positions, how serials are checked and which measurement practice the workshop uses. Maintenance Reviewer supplies the operating criteria for a decision. A numerical reading by itself should never be presented as a universal replacement rule. Keep the measurement unit visible during imports and daily entry.

Choose a load whose assignment can be checked with the inspector. Agree how staff identify the relevant vehicle if that load has several assignments. Decide who corrects a mistaken serial before submission and how the team preserves an already reviewed observation when later evidence differs. Use the organization’s time zone consistently when comparing inspection dates.

During a rehearsal, Tire Inspector records tire TM-214 at the left rear position with a depth of 7 thirty-seconds. An earlier observation shows the same serial at another position. Maintenance Reviewer follows the dated observations and the supporting attachment before deciding whether the current request concerns rotation or replacement. The fleet’s maintenance policy governs the decision in this rehearsal.

Next, substitute the vehicle on the parent load. The inspector must still be able to explain which assignment belonged to the inspection. If the new assignment makes that unclear, stop the decision and resolve the evidence. A load reference alone should not cause the team to attribute the old reading to the replacement vehicle.

• Custody Board by Status — Follow tire inspection work from Draft through review and completion.
• Loading Handoffs Default List — Read the submitted tire observations and supporting context before the maintenance decision.

Prepare and submit an inspection, then review rotation or replacement. Use the data model to prepare import mappings.
