Some useful tips:

 

  • Load and Inflation Pressure: Avoid overloading the tires and never drive them when it is over-inflated or under-inflated. For recommended inflation pressure and load readings, please refer the manufacturer manual
  • Rim: Use of recommended rim size is mandatory.
  • Tube: Always use a new tube with a new tire.
  • Water Filling: In order to achieve excellent traction, tire can be filled with water. This will not harm the tire or influence its driving properties if the correct process is followed. Areas with cold climate, it is advisable to add anti-freeze substances.
  • Mounting and Dismounting: Correct mounting and dismounting procedures should be practiced. Safety precautions are necessary while performing mounting and dismounting procedures.
  • Storage: Storage of tires for more than a few months is not advisable. Tires should be stored in dark and cool place, free of dirt and oils and should be away from running electric engines.
