OKO - Should be installed prior to the puncture rather than as a puncture repair. OKO - Deals with the loss of air and provides a permanent seal to any hole up to 10 mm. Can this be used as a puncture repair - Yes - If used as a puncture repair - When the tyre deflates during driving - locate the puncture and remove the object - install the correct amount of sealant into the tyre - re-inflate and spin the wheel to make a permanent seal - for heavier vehicles you would need to drive the vehicle around so that the Oko seals the puncture.
