The number moved, and both sides could audit it
Every engagement starts with a written baseline captured in shadow mode. These are the outcomes design partners are working toward, with the wedge, the method and the measurement stated plainly.
Programs running across these segments
Six engagements, six wedges
Each one started on a single cell with one metric.
Passenger radial plant cuts splice defects at the drum
A high-volume passenger line moved splice verification from audit sampling to per-component measurement and corrected drum tension in the loop.
-38% splice defect rate over 12 weeks [ASPIRATIONAL]
Read the summaryTruck and bus plant recovers cure energy without touching quality
Adaptive dwell against per-tire cure-state estimation replaced a fixed recipe carrying a decade-old safety pad.
-6.1% cure energy, zero cure escapes [ASPIRATIONAL]
Read the summaryOTR plant localizes cord shift to a single drum
Fusing X-ray and shearography with build evidence traced a recurring cord-shift signature to one drum servo calibration.
4 escapes prevented in the first month [ASPIRATIONAL]
Read the summaryGrade mix improved by predicting force variation upstream
Predicting radial force variation from build and cure evidence turned downstream sorting into upstream correction.
+1.4 pts grade A rate [ASPIRATIONAL]
Read the summaryAudit preparation collapses from weeks to an afternoon
Linked genealogy and an immutable action log turned an IATF evidence request into an export.
NCR closure 11.4 → 3.1 days [ASPIRATIONAL]
Read the summaryPress bank rebalanced without new equipment
Mold allocation and cure sequencing solved together moved the constraint off the press bank.
Takt 66 s → 61 s [ASPIRATIONAL]
Read the summarySplice defects at a passenger radial plant
The most common first wedge, and the clearest illustration of why station-level measurement beats downstream sorting.
Audit sampling and a four-hour feedback loop
Splice quality was verified by periodic audit and confirmed at final inspection. By the time a drift was visible, hours of production carried the same fault, and root cause was reconstructed from memory and paperwork.
- Sampled verification, not per-component
- Feedback measured in hours, not seconds
- Root cause reconstructed manually after the fact
Per-component measurement with correction in the loop
Treadum measured overlap and gap on every component, scored open-splice risk before the tire left the station, and corrected drum tension and placement offset inside the signed envelope. Faults that remained were held at the drum with evidence attached.
- Every component measured, none sampled
- Correction applied within the same build cycle
- Findings localized to builder, drum, roll and batch
- Overrides captured as structured training data
How the measurement was done
The method matters more than the number, because the method is what makes the number believable.
Baseline
Thirty days of production captured across all shifts, constructions and compounds, with no Treadum writes and no process changes.
Shadow
Predictions compared against engineer judgement and downstream inspection results; accuracy and false-hold gates measured.
Assist
Engineers committed every proposal. The wedge metric began moving and override reasons were coded.
Bounded
Low-risk corrections executed automatically inside the signed envelope, with weekly gate review.
Attribution
Effects attributed per agent and per action class from the same immutable log both parties read.
Wedge outcomes at a glance
| Engagement | Wedge metric | Baseline | After 12 weeks | Status |
|---|---|---|---|---|
| Passenger radial · line B | Splice defect rate | 0.50% | 0.31% | [ASPIRATIONAL] |
| Truck & bus · press bank 3 | Cure energy per tire | Index 100 | Index 93.9 | [ASPIRATIONAL] |
| OTR · X-ray station | Escapes prevented | — | 4 in month 1 | [ASPIRATIONAL] |
| Passenger radial · grading | Grade A rate | 94.8% | 96.2% | [ASPIRATIONAL] |
| Group · quality systems | NCR closure time | 11.4 days | 3.1 days | [ASPIRATIONAL] |
| Passenger radial · press bank | Takt | 66 s | 61 s | [ASPIRATIONAL] |
All figures are design-partner targets or in-flight pilot results and are marked [ASPIRATIONAL] until published with partner permission.
What the teams said afterwards
“We had three people watching X-ray images and still shipped uniformity rejects. Treadum flagged the cord shift at the building drum, not four hours later at final inspection.”
“The cure agent found 40 seconds of margin on a construction we had run the same way for eleven years. It proved it in shadow mode before it touched a press.”
“Genealogy is the part I did not expect to care about. Every tire now has a linked record from batch to grade, and audit prep went from weeks to an afternoon.”
[PLACEHOLDER] Design-partner quotes are illustrative until pilot references are published.
Why the second line is faster than the first
- Connectors reused: The integration pattern for your PLCs, historian and inspection machines is already written and tested.
- Envelope templated: Action classes, limits and approver roles carry over; only thresholds are re-tuned locally.
- Models transfer: Perception models transfer well across similar constructions; process models are re-fit on local data.
- Gates known: Everyone already knows what shadow, assist and bounded mean and what has to be true to pass.
- Baseline discipline: The team has done a rigorous baseline once, so the second one takes days rather than weeks.
Consistent patterns so far
How to read these results
Because Treadum is early and we would rather be trusted than impressive. Figures marked [ASPIRATIONAL] are targets or in-flight pilot results that have not yet been published with partner permission and third-party verification.
Once a partner has agreed to reference calls, yes. Ask during the plant walk and we will tell you honestly who is available and who is not.
Baselines cover a full production cycle across shifts, constructions and compounds, are captured before any writes, and are agreed in writing by both sides before autonomy is activated.
Legacy inspection machines with no usable output remain read-only, and sites without linked historian data take longer to reach useful cure and rheology models. We will tell you which category you are in during the plant walk.
Put one cell on autonomy in 90 days
Pick one wedge — splice inspection, X-ray defect detection, cure-state optimization or uniformity prediction. We baseline it, run shadow mode, then graduate to bounded autonomy under a signed control envelope.
Pilots start in shadow mode. No line changes until accuracy and safety gates pass.
