PREVENT A FLAT MYO (Mix Your Own) is a mix yourself liquid tyre sealant. By mixing it yourself and adding your own liquids all of the savings are passed onto you.

Once mixed into a liquid, PREVENT A FLAT MYO is pumped into a tyre through the valve stem. The valve is reinserted and the tyre is inflated to normal operating pressure. As soon as the vehicle moves PREVENT A FLAT MYO is activated.

PREVENT A FLAT MYO traps fibres, fillers and inhibitors in suspension sealing punctures by the movement of the vehicle along with the tyres own air pressure when attempting to escape through a leak. PREVENT A FLAT MYO is beneficial in both tubeless and tubed tyres with its ability to seal most leaks as they occur with minimal air pressure loss.

Being a liquid PREVENT A FLAT MYO coats the interior of the tyre as the vehicle moves with millions of fibres held in suspension within the liquid. It is these fibres that plug the leak, while the fillers seal the leak and the inhibitors protect your tyres and rims.

When a puncture does occurs that point of the tyre is under load, the air in the tyre tries to escape taking the fibres out of suspension forcing them into the hole.

As the leak comes off the point of load, the stress on the tyre is relieved and the compound surrounding the leak contracts. This traps the fibres and fillers already in the hole, binding them tight and cutting off any air flow from within the tyre.

As the tyre is subjected to continued rolling, the leak will come onto the load point with each revolution. As it does so the compound flexes and even more fibres and fillers are forced into the hole. Again, as the leak rolls off the load point the compound contracts binding the fibres even tighter into the leak area.

The plug formed in this way is completely flexible. It expands and contracts with the flexing of the tyre.

Under operational conditions this process is virtually instantaneous, resulting in minimal air loss from the tyre.

The plug formed by the fibres is then set by the fillers to a permanent seal only using a fraction of the PREVENT A FLAT MYO

Once PREVENT A FLAT MYO has been installed it is operable for the service life of the tyre.
