Preventive maintenance in the tyre industry refers to a structured, schedule-driven approach to servicing equipment — curing presses, internal mixers, calenders, tyre building machines, and more — before failures occur rather than after them. In a sector where a single unplanned breakdown on a curing line can cost upwards of $15,000 per hour in lost production, shifting from reactive to preventive maintenance is one of the highest-ROI decisions a plant manager can make.
According to a Reliable Plant industry study, manufacturers that operate mature preventive maintenance programs reduce unplanned downtime by up to 45% and cut overall maintenance costs by 25–30%. Yet many tyre plants still rely on paper-based job cards, manual inspection rounds, and tribal knowledge to maintain equipment that runs 24 hours a day, six or seven days a week.
This guide covers how to build a solid preventive maintenance programme specifically for tyre manufacturing — the key equipment to prioritise, the right PM intervals, and how a modern preventive maintenance software like Cryotos CMMS automates the entire process so nothing slips through the cracks.
Tyre plants operate in one of the most demanding production environments in manufacturing. Equipment runs continuously under extreme heat, pressure, and mechanical stress. Curing presses cycle at temperatures above 170°C. Internal mixers process highly abrasive rubber compounds that tear through seals and blades. Calender rolls handle materials at precise tension settings that drift the moment a bearing wears beyond tolerance.
In this environment, breakdown maintenance isn’t just expensive — it’s dangerous. The OSHA lockout/tagout standard (29 CFR 1910.147) requires strict energy isolation procedures any time maintenance is performed on energised equipment.
Beyond safety, the financial case for preventive maintenance in tyre manufacturing is overwhelming:
Preventive maintenance breaks this cycle by replacing random, unpredictable failures with planned, controllable maintenance events that happen on your schedule — not the equipment’s.
Tyre manufacturing involves a complex sequence of production stages, each with specialised equipment that requires its own maintenance approach. Prioritise your PM programme around these asset categories:
The internal mixer is where rubber compounding happens — raw rubber, carbon black, and chemical agents are blended under heat and pressure. Key PM tasks: rotor tip clearance checks, drop door seal replacements, hydraulic ram inspection, temperature sensor calibration, gearbox oil analysis.
Calenders apply rubber compound to textile or steel cord fabrics at precise thicknesses. Key PM tasks: bearing lubrication and clearance checks, roll surface inspection, hydraulic system pressure testing, nip roll alignment verification, speed synchronisation calibration.
TBMs assemble the tyre carcass layer by layer. Key PM tasks: bladder inspection and replacement (cycle-count-based), stitching roller surface checks, servo motor calibration, bead gripper mechanism lubrication, pneumatic line leak checks.
Curing presses are the most maintenance-intensive assets in a tyre plant. Key PM tasks: curing bladder inspection and replacement (cycle-based), steam system trap and valve checks, hydraulic seal replacement, mould cleaning and inspection, pressure gauge calibration.
Key PM tasks: screw and barrel clearance measurement, die head strip and clean, cooling system flow check, bias cutter blade replacement (cycle-based), guide rail alignment verification.
A well-designed PM schedule for a tyre plant balances calendar-based PM and usage-based PM. The most effective programmes use both.
Common PM failures and fixes: PM on paper but not done (fix: require photo proof); wrong OEM intervals (fix: use MTBF data); parts not ready (fix: link spares to PM work orders); no KPI visibility (fix: track 90%+ compliance rate); spreadsheet schedules (fix: migrate to CMMS).
A CMMS auto-generates PM work orders, stores complete asset history, enforces digital checklists, links spare parts to PM work orders, tracks PM compliance and maintenance KPIs, and integrates with IoT sensors and SCADA systems.
Plants using CMMS software achieve 28% higher PM completion rates and 23% lower maintenance costs per asset compared to manual or spreadsheet-based systems.
Key KPIs: PM Compliance Rate (target 90%+), MTBF, MTTR, Planned vs. Unplanned Ratio (target 80–85% planned), OEE (target 75%+), and Maintenance Cost as % of ARV (benchmark 2–5%).
Tyre manufacturers using Cryotos have reported a 30% reduction in unplanned downtime and 25% faster repair times within the first year. Book a free Cryotos demo to see how other tyre manufacturers have set up their PM programmes on the platform.
A structured programme of scheduled inspections, servicing, and part replacements performed on manufacturing equipment at regular intervals or usage milestones, before failures occur.
Curing presses, internal mixers, and calenders are the three highest-priority asset categories. Tyre building machines and extruders are the next tier.
A CMMS automates scheduling, generates work orders when triggers are reached, enforces digital checklists, links spare parts to PM tasks, and tracks KPIs in real time.
Industry best practice is 90% or higher. A rate below 80% is a warning sign.
Preventive maintenance is schedule-driven. Predictive maintenance is condition-driven — IoT sensors trigger maintenance when a reading indicates a failure is approaching.
Cryotos AI predicts failures, automates work orders, and simplifies maintenance—before problems slow you down.
