Brownfield Tire Plant Auditing - From Raw Material to Finished Product

At Black Donuts, we help tire manufacturers upgrade and expand their existing plants through modular improvements or complete transformations.

With over a decade of hands-on experience designing and improving tire factories worldwide, our experts understand every process, machine, and challenge, because we’ve been there ourselves. We specialize in brownfield auditing and modernization, not general consulting, delivering practical, measurable results.


We work side by side with you to turn insights into real improvements, whether your goal is to increase output, speed up curing, cut waste, or increase automation. Every audit concludes with a phased, risk-free roadmap aligned with your production goals and budget, ensuring upgrades are implemented smoothly, safely, and without unnecessary downtime.


Auditing Objectives
  • Assess current production performance and detect bottlenecks
  • Evaluate automation readiness and modernization potential
  • Determine the current capability from a tire technological point of view and what is needed to improve to answer future requirements
  • Identify opportunities for measurable cost and cycle-time reductions
  • Create a clear roadmap for continuous improvement

OUR APPROACH

Why Us

At Black Donuts, we combine deep technical know-how with real factory experience. Our in-house team of tire designers, material scientists, layout specialists, and automation engineers ensures every recommendation is grounded in practical, hands-on expertise, not theory.

We deliver immediate value through short-term process optimizations that can often be implemented right away, with little or no additional investment.

Our smart data auditing approach goes beyond manual inspections. Using Digital Twin, MES Ontire®, and simulation data analysis, we detect inefficiencies and bottlenecks that are otherwise invisible, turning data into clear, actionable insights.

With strong sustainability expertise through InTire Labs, we integrate bio-based and recycled material insights into every audit, helping manufacturers align with evolving ESG requirements.

We don’t just advise, we execute. Our turnkey approach ensures that identified improvements are transformed into upgraded factory capabilities, safely and efficiently.

Our auditing & process optimization services uncover hidden inefficiencies across the entire tire production chain, from material flow to final tire dispatch, and convert these insights into actionable data.

Auditing Process

Check 1. Audit Preparation

We start by collecting production data, KPIs, layout drawings, and historical performance records to define clear focus areas and measurable targets. Together with your team, we agree on the audit scope—layout, machinery, automation, processes, energy use, or all combined—and set KPIs and success criteria aligned with your goals in capacity, efficiency, or sustainability.

Check 2. On-Site Audit

Our experts conduct floor walks, staff interviews, machinery inspections,
and process flow observations to get a full picture of current operations. We assess:

  • Production areas, utilities, material flow, and bottlenecks.
  • Machinery specifications, maintenance logs, and factory layout.
  • Energy use and process efficiency figures.
  • Product platforms, tire constructions, component libraries.
  • Staff assessment, structure, and skill alignment.

Check 3. Independent Data Analysis & Identification

We analyze collected data to identify bottlenecks, quantify losses, and benchmark your performance against best-in-class standards.

  • Detect bottlenecks, safety or compliance risks, outdated equipment, and quality issues.
  • Assess sustainability performance (emissions, waste, recycling opportunities).

Check 4. Recommendations

We propose prioritized improvement actions and a clear assessment of upgrade options, risks, and ROI:

  • Evaluate the technical and financial feasibility of potential upgrades.
  • Identify risks of downtime, integration issues, and hidden costs.
  • Prioritize quick wins vs. long-term strategic improvements.

Check 5. Reporting, Upgrade Scenarios & Presentation

You receive a detailed report including before-and-after performance metrics. We present:

  • Modular and phased solutions tailored to your needs and budget.
  • Present scenarios with investment estimates, ROI, and implementation roadmaps.
  • Engage in Q&A to address client concerns and refine options.

Check 6. Roadmap & Implementation Plan

We deliver a step-by-step, phased implementation plan designed to minimize or eliminate production downtime.
Our plan aligns with your internal teams and external suppliers, ensuring smooth execution.


Check 7. Ongoing Support & Monitoring

We stay involved after implementation by tracking KPIs, providing technical guidance during execution,
validating improvements, and offering continuous support for further optimization.
