Make sure you follow manufacturer’s specific procedures and safety warnings as required. Operation and safety manuals for each Ranger tire changer model can be found on their respective Ranger tire changer product pages – simply look for and click on Download the Instruction Manual (as illustrated here). Additional information about mounting and demounting tires is available on the Rubber Manufacturers Association (RMA) website by requesting itsDemounting and Mounting Procedures wall chart, or by requesting information from the Tire Industry Association (TIA) for its Automotive Tire Service Reference Aids and Materials.

  • Loosening the beads
  • Clamping the tire / wheel assembly
  • Demounting the upper bead
  • Demounting the bottom bead
  • Lubrication of both beads
  • Installing the bottom bead
  • Installing the upper bead
  • Seating the beads with air pressure
  • Inflating to the proper PSI

Tire technician should always first identify the type of wheel involved and how a tire should be changed on that particular wheel. A number of things must be first considered and checked due to variances in wheel configurations. There are a number of safety measures that should be observed when changing a tire. Danger warnings and precautions are pointed out completely in a new wall chart issued recently by the RMA.

How to mount a wheel on a tire changer from Ranger Products 


Be sure to read and understand all WARNINGS as illustrated on the equipment labels or as shown in the operators manual prior to operation of any tire changing machine. Failure to comply with proper safety instructions may lead to serious harm or even death of operator and/or bystanders.

  • Only trained operators should operate tire changing machines. All non-trained personnel should be kept away from work area.
  • Never let non-trained personnel come in contact with, or operate machine.
  • Keep hands clear of all pinch points.
  • Always check tire changer for damaged parts prior to operation. Do not use machine if any part(s) are broken or damaged.
  • Never exceed the factory recommended air pressure of tire. Over inflating the tire beyond the manufacturers recommendation can cause tire burst or explosion.
  • Operators should inspect all tires and rims for possible defects prior to mounting.
  • Do not attempt to mount defective tires.
  • Never mount a tire on a defective wheel.
  • Always make sure tire size matches rim size prior to mounting. Mismatched tire / rim combinations can explode.
  • Tire changers are not intended to be a restraining devise for exploding tires, tubes, or rims.
  • All operators should take proper precautions to implement safety and to avoid personal injury or harm.
  • Do not approach or lean over tires while inflating.
  • Keep hands and body clear at all times and as far back as possible during inflation.
  • An exploding tire, rim or other wheel component can cause death to operator and/or bystander. Remain clear at all times.
  • To inflate tires, use short bursts while carefully monitoring the pressure, tire, rim, and bead.
  • While seating beads, never exceed 40 PSI. If bead does not seat at 40 PSI immediately relieve pressure and check for damaged bead and/or other cause.
  • Do not aim bead-seating nozzles towards yourself or any person. Bead-seating nozzles must always be aimed toward tire bead area only.
  • Hold bead-seating nozzles securely with both hands at all times.
  • Always use good quality tire lubricant when servicing tires.
  • Consider work area environment. Do not expose equipment to rain. Never operate machine in or around water or damp environments. Keep area well lighted.
  • Dress properly. Never wear loose gloves, clothing or jewelry. They can be caught in moving parts. Non-skid steel-toe footwear is recommended when operating tire changer. Wear protective hair covering to contain long hair. Approved back-support braces are recommended when handling heavy loads.
  • Always wear safety goggles when operating a tire changer.
  • Tire changers must be grounded while in use to protect the operator from electric shock.
  • Always unplug tire changing machine before servicing. Never yank cord to disconnect it from the receptacle. Never operate machine in or around water or damp environments.
  • Tire changers have internal arcing or sparking parts which should not be exposed to flammable vapors.

Demounting and mounting tires can be hazardous. This information is NOT meant as a substitute for proper training. The illustrations shown here are consistent with those used by major tire changer manufacturers, but consult their specific equipment use procedures and instructions.
