What this is
What is a tyre "compliant" against on this record?
What is a tyre "compliant" against on this record?
Compliant means the tyre meets both the legal tread depth minimum for its category and any tighter company minimum set in policy, has no cuts, bulges or cord exposure, and is correctly rated, pressured and matched for its axle position. All of those conditions have to hold together; meeting the legal figure alone is not enough to mark a tyre compliant here.
What is the difference between the legal minimum and the company minimum tread depth?
The legal minimum is the statutory tread depth below which the vehicle cannot lawfully be on the road. The company minimum is a tighter operational threshold, usually set to allow tyres to be scheduled for replacement before they reach the legal limit, so a tyre can fail the company standard while still being technically legal.
What does "matched tyres on axles" mean and why does it matter?
It means tyres fitted to the same axle, or across a twin-steer or drive pair, are the same size, construction and broadly the same tread depth. Mismatched tyres on one axle affect braking balance and handling and can themselves constitute a roadside defect independent of any single tyre's own condition.
Scope
When is a tyre management record required?
This record is the periodic tyre management review. Using it for a driver's daily walk-round check, or for the vehicle's broader safety inspection, spreads the same evidence across templates that are each meant to answer a different question.
Use this template when
- A tyre check is due at the set interval, or has been triggered by a wear complaint or reported defect
- The vehicle register is being set up and this template needs installing against it
- You are running the Fleet and Driver Compliance programme and this is one of its steps
- A linked record, such as the vehicle inspection or a defect report, needs this tyre history to exist
- Tyre work was carried out under a scheduled service and needs cross-referencing back to that service
Do not use it for
- Tyre Condition Record, which is the driver's pre-use walk-round check completed before the vehicle moves, not the periodic management review recorded here.
- Vehicle Service Record, which records a scheduled vehicle service, what was done, parts used and the next due point.
- Vehicle Safety Inspection, which records the periodic safety inspection of a commercial vehicle to the required standard, with defects classified.
- Refrigeration Unit Service Record, which records service and performance testing of a transport refrigeration unit, including temperature pull down and refrigerant.
- Anything outside KnowFleet, which belongs in the workspace that owns that process
Compliance mapping
Which ISO 55001 cl.8.1 requirements does this satisfy?
ISO 55001 cl.8.1 requires operational control of activities that keep the asset fit for use; on a tyre, that control is exercised through measurement, not observation.
| Clause | Requirement | Where it lands |
|---|---|---|
| ISO 55001 cl.8.1 | Tyres are checked at the set interval against defined condition criteria, not on an ad hoc basis | Condition |
| ISO 55001 cl.8.1 | Tread depth is verified against both the legal minimum and any tighter company minimum | Condition |
| ISO 55001 cl.7.1 | Pressures are set and checked cold, to the tyre's correct load and speed rating | Pressure and fitment |
| ISO 55001 cl.8.1 | Retreads are fitted only where policy and axle position permit | Pressure and fitment |
| ISO 55001 cl.10.1 | Uneven wear is investigated for a root cause, such as alignment, rather than logged and left | Management |
| ISO 55001 cl.7.5 | The record is retained and cross-referenced to the service it relates to | Related records |
| ISO 55001 cl.9.1 | The compliance outcome per vehicle is measured and recorded at the point of decision | Outcome |
What it does not cover
- Tread Depth Above Legal Minimum marked Yes with no measurement recorded anywhere on the file, which leaves the check unverifiable against the figure it depends on.
- Uneven Wear Investigated marked Partly with Alignment Checked Where Indicated marked N/A, which lets a wear pattern that usually points to a geometry fault go untraced.
- Matched Tyres On Axles marked Fail while All Tyres Compliant reads Yes, which contradicts the individual finding it is supposed to summarise.
- Tyres Replaced left blank when Immediate Defect Found reads Yes, which hides whether the defect was actually resolved on the day it was found.
- Service Record ID left blank when the tyre work followed a scheduled service, which breaks the link back to the job the work was carried out under.
Global
Tyre Management Record requirements by country
Tyre condition sits at the intersection of vehicle construction rules and roadside enforcement, and the specific threshold that matters shifts depending on where the vehicle runs.
FMCSA 49 CFR 393.75
Sets minimum tread depth requirements by tyre position and prohibits tyres with exposed cord, cuts extending to the ply, or mismatched sizes on the same axle.
Enforcement checks the tyre itself against the regulation's figures directly; a fleet record that only says 'Yes' with no depth logged gives the driver nothing to point to at a roadside stop.
Road Vehicles (Construction and Use) Regulations 1986, reg. 27
Sets the legal tread depth minimum and prohibits defects such as cuts, bulges and exposed cord across the tyre's structure.
A vehicle can be prohibited from further use immediately at the roadside for a single non-compliant tyre, independent of anything else on the vehicle's maintenance file.
Directive 2014/45/EU, periodic roadworthiness testing
Requires tyre condition, including tread depth and structural integrity, to be assessed as part of the periodic test regime member states must run.
A management record showing a consistent internal tyre check programme supports the vehicle at its periodic test rather than leaving that check to happen for the first time at the test itself.
How to complete it
How to complete a tyre management record, step by step
The single-choice fields are quick to complete. The judgement calls below decide whether a compliant tyre answer here would actually survive a roadside check.
A tyre above the legal minimum but below the company minimum is not a roadside defect, but a defensible fleet still treats it as an action item: schedule replacement before the next interval rather than waiting for the legal threshold to be reached, since that is the entire point of setting a tighter company figure.
Even Wear Pattern or Uneven Wear Investigated marked Partly should not leave Alignment Checked Where Indicated on N/A. A defensible position treats any Partly on wear as "indicated" by definition, meaning the alignment field must resolve to Yes or No, never N/A, before the record closes.
For twin or dual-wheel positions, matched means the same size, construction and a comparable tread depth across the pair, not just the same brand. A mismatch in depth alone, even with identical tyres, is enough to fail Matched Tyres On Axles, because the smaller-diameter tyre carries a disproportionate share of the load.
Most fleets restrict retreads from steer axles regardless of what the record's policy field says, because steering-axle failure has a materially different consequence than a trailer or drive-axle failure. Where written policy doesn't specify, the safer default is steer-axle exclusion, not permission by omission.
What auditors find
Most common tyre management record findings
These are the patterns that surface most often when a tyre history is reviewed after a roadside prohibition or a wear complaint.
| Finding | Clause | What fixes it |
|---|---|---|
| Tread depth answered Yes against both thresholds with no measured figure logged elsewhere on the vehicle file | ISO 55001 cl.8.1 | Require a numeric depth reading per position to be captured alongside the pass/fail answer, not instead of it. |
| Company minimum failed while legal minimum passes, with no action raised | ISO 55001 cl.8.1 | Route any company-minimum failure to Action Required automatically, even when the legal threshold is still satisfied. |
| Retreads recorded as used with no axle position noted | ISO 55001 cl.8.1 | Capture axle position on every retread entry so a steer-axle restriction is actually enforceable, not just declared. |
| Alignment left on N/A despite an uneven wear finding on the same record | ISO 55001 cl.10.1 | Block N/A on the alignment field whenever wear investigation reads anything other than clean. |
| Old Tyres Disposed Correctly marked Fail with no linked waste transfer evidence | ISO 55001 cl.7.5 | Require a disposal reference or note whenever this item fails, so the gap is visible rather than closed silently. |
| Tyre Contract Performance Reviewed answered No across several consecutive cycles | ISO 55001 cl.9.1 | Escalate persistent non-review to the maintenance programme owner rather than letting it repeat unaddressed. |
Case in point
Case in point: the matched-axle failure that passed on paper
A trailer's tyre record showed Tread Depth Above Legal Minimum as Yes on every position and Matched Tyres On Axles as Pass, completed from a visual walk-round rather than a gauge and a tape measure across the pair.
A roadside inspection found one tyre on a dual fitment measurably shallower than its pair, enough to be classed as mismatched under the applicable construction and use rules. The prior record had nothing to contradict: no depth figures, no note on the pairing, just two boxes both ticked Pass on the same visit.

From a document you fill in to a programme that runs itself
The form is the easy part. Measuring rather than eyeballing, chasing the wear pattern back to a cause, and keeping the contract under review is the work that actually slips.
Holds the tyre history against the vehicle register, flags recurring wear patterns across the fleet, and keeps the check linked to the service it was carried out under.
Schedules the next tyre check against the set interval and surfaces vehicles overdue before they miss a cycle entirely.
Checks completed tyre records against roadworthiness thresholds and flags where legal and company minimums have been treated as the same figure.
Coordinates the crew across tyre, service and inspection records, rolling exceptions into one view and holding every write for your approval before it touches a record.

Tyre Management Record definitions and key terms
- Legal minimum tread depth
- The statutory tread depth threshold below which a tyre cannot lawfully remain in service, set by the applicable construction and use or federal motor carrier regulation.
- Company minimum
- A tighter internal tread depth threshold set to schedule replacement ahead of the legal limit, distinct from and stricter than the statutory figure.
- Retread
- A tyre casing that has been re-manufactured with new tread, subject to fleet policy on which axle positions may carry them.
- Matched tyres
- Tyres on the same axle or dual fitment that share size, construction and a comparable tread depth, checked because mismatches affect braking and load distribution.
- Cold pressure check
- A tyre pressure reading taken before the vehicle has been driven, since pressure rises with heat and a warm reading understates a genuine underinflation.
FAQ
Frequently asked questions about tyre management record
How often should a tyre management record be completed?+
It runs at the interval set in the maintenance plan, with additional targeted checks triggered by a reported wear complaint, a defect, or a change in loading pattern.
Does this record replace the driver's daily tyre check?+
No. The driver's pre-use walk-round is a separate, more frequent check; this is the periodic management review that measures condition, pressure and fitment in more depth.
What happens if a tyre fails the company minimum but not the legal minimum?+
The vehicle can remain on the road, but a defensible fleet schedules replacement before the next interval rather than waiting for the legal threshold to be reached.
Why does the record ask about tyre contract performance?+
Because recurring wear or compliance failures often trace back to the supply or fitment contract rather than any single vehicle, and that pattern only becomes visible if it is reviewed on a cycle.
Who signs off a tyre management record?+
Fleet maintenance completes the technical checks, with a second signature from the transport function confirming the outcome before the vehicle is returned to service.
Does replacing a tyre close the record automatically?+
No. Tyres Replaced records the count, but the outcome fields, including All Tyres Compliant and Result Band, still need to reflect the vehicle's condition after replacement, not before it.
