Guideline on Buying Tires How Tire Service Technicians Assess Issues | Page 7

Starting the Repair Job
When assessing the car tire, the technician starts by removing the damaged part from the car after the
car is completely stationary (secured and powered down). The tire is removed from its corresponding
rim, so the technician can get a thorough all-around look at the tire. Here, the technician will be able to
spot what may have caused the tire to go flat. Sometimes, a tire can be temporarily repaired while it is
still 'on the wheel.' However, these are usually temporary fixes and usually come off once the
technician is ready to begin the actual repair work.
After the tire is demounted (removed from the rim), the technician starts their thorough inspection.
The inspection itself generally involves assessing the condition of the tire's material and searching for
any foreign object that may have penetrated the tire's hard exterior. Depending on the object, the
puncture could penetrate past the exterior material into the deeper parts of the tire, causing the air to
leak out.
