A flat tire refers to a situation in which one of the tires on a vehicle loses air pressure. It causes the tire to become deflated and no longer functional. This can lead to the tire appearing visibly flat or significantly underinflated. A flat tire can affect a vehicle’s handling, stability, and safety and can result in the need for immediate repair or replacement.
Preventing flat tires involves regular tire maintenance, including checking tire pressure, inspecting for damage, and keeping tires properly inflated. Additionally, driving cautiously, avoiding rough road hazards, and being aware of the condition of your tires can help reduce the risk of flats.
Flat Tire

   Measurement

  • Wearing out tires due to UV rays

Machine

•   Tire quality and age
  • Inferior tire quality
  • Worn-out tires
•   Tire design & construction
  • Tread pattern & material
  •   Inadequate tire sidewall

Method

•   Driving habits
  • Failure to adapt driving to road conditions
  • Aggressive driving
•   Over inflation
•   Low pressure
  • Irregular refilling
•   Puncture by sharp object

Man

•   Inadequate maintenance
•   Rash/ poor driving
•   Vehicle overloading
•   Vandalism

Environment

•   Geographical location
  •   Rough roads or construction zones

A structured cause analysis is always easy to understand when experienced visually. This fishbone is a methodical root cause analysis for flat tire in a vehicle. It shares knowledge about the factors that affect tire condition, internal air pressure which results in leakage or bursting. One can study this template thoroughly to gain knowledge of the contributing factors.

Who should use the Flat Tire template?

• This fishbone is advantageous for anyone who wants to know why a tire does not have enough internal pressure or explodes.

Why use this template?

• It helps anyone who wants to gain knowledge on the factors affecting the tire quality and durability for which it gets deflated or becomes flat.
• This Ishikawa diagram is simple and easy to handle. One can learn an easy way of designing a template with its causes and sub-causes arranged categorically. It is advantageous for analyzing other problems and one can extend it to meet new requirements.
• Draft and create a template for problem analysis in smartQED.
