Tyre Manufacturers should be capable of designing their way out of early tyre failure problems :-
Tyre production facilities traditionally use Date of Manufacture (DOM) Charts to monitor tyre performance . The industry use these Charts as a Diagnostic Tool to assess whether the change in tyre removal rate is either "Design/Manufacture" or "Commercial/Operational" related . This is usually picked up by establishing whether these DOM's start showing Horizontal or Diagonal Trends in the number of monthly removals .
Tyre Industry Failure Data Bases
Tyre Manufacturers do sometimes make mistakes , and don't let them tell you otherwise . We so often see other products being recalled from the field because of some inherent manufacturing deficiency . But this seldom happens with OTR tyres . There is provision for any ISO Accredited Company to recall product from the field if there is any Safety Risk in the failure.
Without collecting all tyre failure data globally it makes it easier for the manufacturers to mask any field problems . The easy way out for tyre manufacturers is to claim that their problems are simply related to Service Conditions , and put the onus back on the end user .
It is accepted that the tyre manufacturing industry is considered a complex one , and therefore can pose some problems in production . It starts with getting both Mould and Tyre Construction right . The next step is being able to incorporate a variety of Raw Materials into a range of different compounds to achieve the right physical properties . Finally , then being able to process these compounds can also be somewhat problematic as well . It is not that simple , there is the possibility of compound scorch , component contamination and gauge variation to name just a few of the potential problems . Not always do they get it right, as is evidenced by some of the historic tyre problems that the industry has seen over the years . Most of the time OEM's are just buying time to either find a solution to the failure mechanism , or just to implement appropriate changes .
The Mining Industry deserves to get better value for money , as budgets are substantial . Having the ability to look at failure rates from a number of different perspectives will allow STS to assist the Mining Industry to address these matters directly with the OEMs and get more responsive and prompt action . It starts with Diagnosing or Categorizing failures correctly so the data has some integrity . Most Tyre Management data bases do not provide the relevant data to address this problem properly . There are a number of Secondary Failure Mechanisms that continuously go unreported. Fixing these problems will go a long way to improving the Overall Integrity of the product and hence make them Safer to use .
