A tire log must be able to track the same tire across different wheel positions. Writing only "front tire worn more" cannot separate the effects of rotation, pressure deviation, road conditions or mechanical problems.
Fix the Recording Method before Comparing
Check the tire specification and cold pressure requirements against the manual corresponding to the Wuling Yangguang passenger version, and record the inspection conditions and the tire identity. NHTSA material can serve as a general maintenance reference; it is not directly Paraguay's legal wear limit and does not provide measured conclusions for this vehicle.
| Finding | Supplementary record | Direction for handling |
|---|---|---|
| Uneven wear between sides | Position, measured location and usage records | Refer to a tire professional |
| Repeated abnormal pressure | Measuring conditions, inflation and re-checks | Find the cause, not just keep inflating |
| Cuts or bulges | Photograph location under safe conditions | Stop normal use and assess |
The observation sheet can reserve separate columns for the tire identity and the current wheel position; the inspector confirms that the physical item corresponds to the records before filling in the result per the applicable method. If the material only has a vehicle number and cannot be traced to a tire, look up installation and rotation records first. Historical data without a clear identity keeps its question mark and is not forcibly stitched into one continuous wear curve.
The technical lead is advised to define the inspection location and conditions, and the executor keeps the actual measurement information and the method used. Locations that cannot be viewed safely are noted as not inspected; tires with obvious anomalies are referred for professional assessment. Do not keep using a vehicle under judgment just because continuous records are needed.
Update Identity after Rotation without Erasing History
Record the original position, the new position and the operation date. After replacement, alignment or repair, re-check under the applicable arrangements; without an inspection, "uneven wear resolved" must not be written.
For uneven wear, attach position photos, usage tasks and recent job records and ask a professional which items need checking. The driver describes the observed symptoms, dispatch provides task changes, and recording staff do not turn these descriptions directly into liability attribution. After inflation or adjustment, keep recording the real results; reasons for not inspecting stay pending.
When arranging rotation, record the actual removed-from and moved-to positions, then have a reviewer confirm against the physical item and note the inspector. When tires are replaced, keep where the old tire went and where the new one came from; the vehicle record continues, but tire identities stay separate. Follow-up conditions after repair or alignment are set by the responsible technician; do not set a uniform limit on your own.
Re-Checking Uneven Wear after a Gap in Position Records
Example only; the contract and the physical vehicle prevail. Uneven wear is found again on a given VIN, but the previous rotation did not record where the tires went. First look up the real records from the work orders and the executor; parts still undetermined are honestly noted, and a current physical inspection is arranged. Do not guess a tire's original position from which one wore more.
After the professional confirms the follow-up handling, record the authorized actions and what was actually done. Later comparisons use only data with a clear identity and inspection conditions; historical gaps are explained separately. In purchasing or operations discussions, unverified changes are not written as established conclusions about tire quality, driving habits or route problems.
FAQ
Is watching the tire pressure warning enough?
Required checks cannot be skipped just because there is no warning.
Does uneven wear always come from driving habits?
Check the tires, the vehicle and usage conditions first; do not attribute blame directly.
Can every vehicle use the same pressure?
Follow the applicable requirements for the corresponding vehicle and tire.
Should old data be deleted after a tire replacement?
Keep the old records and create a new identity entry for the new tire.
When discussing fleet vehicle maintenance material, state the tire specification, the usage tasks and the anomalies already observed, via the Starvia contact page or WhatsApp.
