Installation instructions for all pneumatic tyres

DIY installation for on-road vehicles when balancing is necessary

  1. Using a measuring jug, decant the required amount of sealant per tyre into the pump container.
  2. Screw the white disposable pump onto the container.
  3. Using a valve core remover, remove the valve core from the inside of the tyre valve by turning it anti-clockwise. Let majority of the air out the tyre.
  4. Push the end of the clear hose pump onto the tyre valve. Make sure it is a tight fit.
  5. Prime the pump just before the sealant reaches the end of the clear tube at the tyre valve. You are now ready to pump the correct amount of sealant into the tyre.
  6. Each hand pump does approximately 30ml of sealant. (We recommend that you put the correct amount of sealant into the container for 1 tyre at a time as in step 1, this is to ensure balancing is not effected).
  7. Start pumping the sealant into the tyre as per recommended dosage.
  8. Once the correct amount of sealant has been inserted, screw the valve core back into the valve of the tyre in a clockwise motion.
  9. Inflate the tyre to the correct pressure and drive the vehicle for a minimum of 8 km at a maximum speed of 40km/h. This ensures the sealant forms a uniform layer inside the tyre and becomes fully effective.
  10. (Optional) - If there are any existing puncturing objects in the tyre, only remove the puncturing objects until step 9 has been completed. After removing the puncturing object, the vehicle must be driven again to ensure the sealant moves into the puncture zone. If the vehicle is left stationary when the object is removed, the sealant may not plug the puncture until the vehicle is driven again

Terms and Conditions

  • Post installation, the vehicle is required to drive no less than 8km for the sealant to be spread evenly and form a consistent and cohesive bond in the tyre. This can yield the sealant ineffective.
  • All pre-existing objects/punctures to be removed after the vehicle has been driven as above.
  • On removal of pre-existing objects/punctures, the vehicle should be driven immediately after for the sealant to plug the punctures. (The fibres in the sealant need to be distributed to create a plug).
  • Any structural compromise of the tyre may yield the sealant ineffective. Make sure the tyre has been inspected and must adhere to road legal standards. Ultraseal is not designed to seal a side wall puncture or tear. The sealant will seep out of the damaged zone to indicate a more serious problem.
  • If the vehicle is not balanced prior to installing Ultraseal, this may exacerbate the imbalance. Possible causes: wheels are out-of-round, tyre damage, incorrect tyre fitment and alignment, miscalibrated or bent wheel axles. We recommend a high speed balancer.
