| 1. | Identify and inflate tires correctly for the size and ply. |
| 2. | Place wheels on balancing machines to determine counterweights required to balance wheels. |
| 3. | Raise vehicles using hydraulic jacks. |
| 4. | Remount wheels onto vehicles. |
| 5. | Locate punctures in tubeless tires by visual inspection or by immersing inflated tires in water baths and observing air bubbles. |
| 6. | Unbolt wheels from vehicles and remove them, using lug wrenches and other hand and power tools. |
| 7. | Reassemble tires onto wheels. |
| 8. | Replace valve stems and remove puncturing objects. |
| 9. | Hammer required counterweights onto rims of wheels. |
| 10. | Rotate tires to different positions on vehicles, using hand tools. |
| 11. | Inspect tire casings for defects, such as holes and tears. |
| 12. | Seal punctures in tubeless tires by inserting adhesive material and expanding rubber plugs into punctures, using hand tools. |
| 13. | Glue boots (tire patches) over ruptures in tire casings, using rubber cement. |
| 14. | Assist mechanics and perform other duties as directed. |
| 15. | Separate tubed tires from wheels, using rubber mallets and metal bars, or mechanical tire changers. |
| 16. | Patch tubes with adhesive rubber patches, or seal rubber patches to tubes using hot vulcanizing plates. |
| 17. | Inflate inner tubes and immerse them in water to locate leaks. |
| 18. | Clean sides of whitewall tires. |
| 19. | Apply rubber cement to buffed tire casings prior to vulcanization process. |
| 20. | Drive automobile or service trucks to industrial sites in order to provide services, and respond to emergency calls. |
| 21. | Prepare rims and wheel drums for reassembly by scraping, grinding, or sandblasting. |
| 22. | Order replacements for tires and tubes. |
| 23. | Roll new rubber treads, known as camelbacks, over tire casings, and mold the semi-raw rubber treads onto the buffed casings. |
| 24. | Buff defective areas of inner tubes, using scrapers. |
| 25. | Place casing-camelback assemblies in tire molds for the vulcanization process, and exert pressure on the camelbacks to ensure good adhesion. |
