1. How can I install TYRESAFE into the tyres of my car?
TYRESAFE is installed into the tyres of a car by trained staff for two reasons: the tyres require balancing prior to installation and it is imperative that the correct amount of TYRESAFE for the specific tyre size be installed since the amount differs a mere 10ml between tyre sizes. Look for TYRESAFE installation points where trained staff with welcome you.

2. How is TYRESAFE* applied to a tyre?
TYRESAFE is applied with the use of a pressure applicator pump through the air valve of the tyre. The valve core is removed and the pump connector is immediately attached over the valve stem. It is not recommended to try and pump against pressures above 50 PSI (3.5 BAR). The pump should be calibrated to the correct amount of TYRESAFE required for the tyre size. It is best not to force the pump handle down nor apply rigorous or hard pressure as this may cause TYRESAFE to seal the valve stem during the application (TYRESAFE is designed to seal holes under pressure). In the event that the valve stem does become blocked, prodding the aperture gently with 1mm wire or a quick blast of the airline may clear the valve stem. After TYRESAFE has been installed, the pump connector is removed, the valve core is re-inserted, and the tyre re-inflated to the correct pressure.

3. Does TYRESAFE* contain any harmful ingredients?
No, TYRESAFE contains no harmful ingredients and does not need to display harmful warning signs on the product packaging. A unique characteristic of TYRESAFE is that it is COSHH friendly (Control of Substances Hazardous to Health). This means that a TYRESAFE user does not need to be educated in the safe handling of the product during use.

4. Does TYRESAFE* affect the tyre structure?
No. RAPRA (Rubber And Plastics Research Association) tests have demonstrated that TYRESAFE has no detrimental effects on the tyre or tyre structure. Under tests, no apparent changes occurred in the tyre rubber or its components during prolonged exposure to TYRESAFE at varying temperatures (between -40șC and 90șC).

5. Does TYRESAFE* cause any difficulties or problems if it becomes necessary to perform a conventional vulcanized repair or hot or cold cure on the tyre?
No. TYRESAFE can be washed from the tyre with water prior to performing such repairs. However, it is possible to perform a conventional repair on the tyre without having to remove TYRESAFE. All that is required is for the immediate area around the puncture to be cleaned.

6. Will TYRESAFE* seal holes larger than 10mm in diameter?
There have been many cases where TYRESAFE has sealed holes up to 15mm. Also, bolts with varying diameters (between 14mm and 19mm) have pierced the tyres and been sealed by TYRESAFE.
*This is also true for AGRISAFE

7. What will happen if the hole is too large for TYRESAFE to seal?
If the hole is large (between 10mm and 19mm), TYRESAFE will attempt to seal the hole. TYRESAFE will slow down the escaping air until the hole is plugged or until it is fully used up. The result is that you will neither suffer a blow-out nor have to drive on your wheel rim before being able to park safely and change your tyre.

8. Does TYRESAFE function in extreme temperatures?
RAPRA tests have proven that TYRESAFE will remain effective at temperatures ranging from -40șC up to 90șC.

9. How many holes will TYRESAFE* seal?
TYRESAFE will continue to seal holes until it is fully used up.

10. Will TYRESAFE* corrode steel or affect the wheel rims?
No. The TYRESAFE formula includes strong anti-corrosives and rust inhibitors.

11. Will TYRESAFE seal rim or bead leaks?
TYRESAFE was not designed to seal rim or bead leaks, but is has been known to do so.

12. Will TYRESAFE seal sidewall or shoulder punctures?
No. Sidewall and shoulder punctures cause a major weakness in the tyre structure and in such cases, the tyre should be replaced. However, TYRESAFE will attempt to slow down the escaping air until the hole is plugged or until it is fully used up. The result is that you will neither suffer a blow-out nor have to drive on your wheel rim before being able to park safely and change your tyre.

13. Will TYRESAFE* block valve apertures during or after application?
TYRESAFE should not cause a blockage to the valve aperture. However, since TYRESAFE is designed to seal holes under pressure, it is important that excess pressure is not used during the installation process. If a blockage should occur, prodding the aperture gently with 1mm wire or a quick blast of the airline should clear the valve stem.

14. When a valve is opened to check tyre pressures, is it possible that TYRESAFE* will pass back through the valve and clog the pressure gauge?
No, TYRESAFE will not and does not pass back through the valve stem.

15. Does TYRESAFE* block the valve stem from the inside when air pressure is released?
No (note: some vehicles operate at 50% tyre pressure in the desert to effect increased traction for rising up gradients). If the valve stem is placed at 12 o’clock, this would not occur since the physical position of the valve stem will be farthest from the TYRESAFE reservoir. Most large vehicles use tyres with high walls and this is unlikely to occur even with the valve stem at 6 o’clock.

16. Will TYRESAFE cause wheel imbalance in motor cars?
TYRESAFE will cause wheel imbalance only if the tyre is filled with the incorrect amount of the product or if the wheels have not been balanced prior to installation. When installation charts are properly used and the wheels balanced by trained personnel, TYRESAFE will not affect any aspect of the wheel balance.

17. Will TYRESAFE* cause wheel imbalance on larger or smaller vehicles?
No. TYRESAFE does not affect wheel balance on any vehicle, large or small, whose wheels do not require balancing prior to installation of the product.

18. Does TYRESAFE* have a shelf-life or expiry date?
No. TYRESAFE will continue to permanently seal punctures for the legal life-time of the tyre.

19. Will TYRESAFE* dry up inside the tyre?
No. TYRESAFE will dry only as a result of heat caused by the friction of escaping air from a tyre.

20. What will happen if I install TYRESAFE* into my tyres and then park my car for an extended period of time?
Since TYRESAFE does not dry up inside the tyre, if the car is parked for an extended period of time (3 days or more), TYRESAFE will simply collect at the bottom of the tyre. In this case, once the car is re-used, it is recommended to drive at a slow speed (not more than 40km/h) for approximately 100 meters to allow TYRESAFE to re-coat the tread area before resuming normal driving speeds.

21. Will TYRESAFE* work on tubed tyres?
Yes. However, due to the poor quality of certain tubes, no guarantee will be extended by the TYRESAFE installer.
