| How does STT seal a puncture in the tread of a tyre? | STT lays down a protective coating between the inside tread of the tyre and the air within the tyre. When an object penetrates the tread area, the air pressure within the tyre forces the sealant into the puncture, where the rubber particles seal the leak. NB: If it is a nail, it may be pulled out. If it is a screw, it should be unscrewed. |
| Does STT prevent porosity, bead and slow air leaks? | Yes. Air pressure within the tyre forces the sealant towards any weak point. As STT travels ahead of the escaping air, it locates and seals potential leakage areas, helping to maintain air pressure. |
| How much STT should be installed in a tyre? | The required amount is calculated according to the specific tyre size using our formulated tyre chart. For example, a 225/65/15 tyre requires approximately 500 ml (½ litre). You can also contact us directly for the correct application quantity. |
| Does STT work with nitrogen-filled tyres? | Yes. STT can be used in tyres filled with nitrogen. |
| Will STT seal a sidewall puncture? | No. STT may temporarily reduce air loss and help get the driver to safety, but a sidewall puncture compromises the structural integrity of the tyre and requires proper attention. |
| Will STT create a hard plug inside the tyre? | No. STT is designed to remain flexible and move with the tyre as the tyre operates. |
| Does STT dry out or form into balls inside the tyre? | No. Because the tyre is a sealed chamber, evaporation does not occur. STT remains in its liquid condition after installation. |
| Is STT safe and environmentally friendly? | Yes. STT is chemically inert, non-toxic and environmentally friendly. |
| Will STT damage or corrode my rims? | No. STT contains anti-corrosive agents to help prevent corrosion. |
| What types of tyres can STT be used in? | STT can be used in pneumatic tyres, including used tyres and retreaded tyres. |
