What if a puncturing object (e.g. a nail) remains in a tyre?
A. OKO z7 will seal around a nail. If a nail moves and enlarges the hole then more OKO z7 will move into the enlarged hole and seal it again. Whilst gaps around the nail are plugged, OKO z7 may lubricate sufficiently for the nail to be ejected. In this case, OKO z7 will reseal the hole whilst the tyre is moving. Q.
