What is Puncturesafe?
A special blend of polymers, rubber and fibre fillers, uniquely formulated to coat all inner surfaces of a tyre - and seal most punctures as they occur, fast!

So Puncturesafe is a pre-puncture treatment?
Yes, it's a one-off application before getting a puncture. Puncturesafe then stands guard within the tyre, ready to go into action to seal punctures on-the-move. Think superb insurance policy.

How does Puncturesafe work?
When a tyre is punctured, centrifugal forces created by the rotating tyre plus internal air pressure push Puncturesafe gel into the hole. A curing process begins once the gel is exposed to outside air, forming a permanent rubbery seal. It has the ability to seal numerous punctures in one tyre, while the vehicle is in motion.

How is Puncturesafe installed in a tyre?
A specific amount of sealant is injected easily through the air valve (with core removed first), normally without taking off the vehicle's wheels. The tyre is then re-inflated to the correct operating pressure and the vehicle can be driven away.

Can Puncturesafe be put in a tyre after it's picked up a puncture? Will it then seal as normal?
In most cases, yes. But it's important the puncturing object is not removed before installing the sealant. After pumping Puncturesafe in, the tyre is re-inflated and the vehicle driven slowly to distribute the gel. Only then can the object be removed from the tyre, leaving a rubbery plug in the hole.

Is Puncturesafe suitable for most pneumatic-tyred vehicles?
Yes, from a go-kart to the largest dumper. And it's suitable for most types of tyre: tubeless, run-flat, retreaded and nitrogen-filled.

Which grade of Puncturesafe should I use?
There are 3 main grades of sealant:
  • XHD (extra-heavy duty) for slower-moving, off-road vehicles and equipment;
  • HD (heavy duty) for medium-speed applications such as trucks, buses, motorhomes, trailers, etc;
  • High-speed grade for cars and motorcycles (speeds up to 240kph).
Does Puncturesafe extend tyre life?
Yes. The biggest threat to tyre life is excessive heat build-up. The gel's unique properties enable heat to be directed away from the inner crown and shoulders to the wheel rim, so tyres run cooler. And a cooler tyre is less prone to puncturing.

Will Puncturesafe cause balance problems in tyres?
No. Provided a tyre is not underfilled, the sealant will coat the whole inside 2-3mm thick, forming a sort of inner tube. As it is evenly spread, Puncturesafe can't unbalance the tyre.

Will Puncturesafe void tyre manufacturers' warranties?
No. It can only do good to tyres, certainly not adversely affect a tyre's integrity or performance.

Will Puncturesafe maintain its viscosity? Is it thermally stable?
Yes, to both - for the operating life of the tyre. And it's normal operating range of temperatures is -35°C to +150°C.

Apart from sealing punctures, what is another benefit of Puncturesafe?
It eliminates chronic air-loss problems, from bead and valve-stem leaks (where most losses occur) and from normal rubber porosity. Puncturesafe sealant thus helps maintain full air pressure even during long-term storage. Basically, Puncturesafe converts any pneumatic tyre into a self-sealing tyre.

Will Puncturesafe dry up or break down inside the tyre?
No. And the rubbery plug formed in a hole retains its flexibility for the tyre's life - it won't dry up and fall out. Puncturesafe's abilities and performance are not diminished by time or distance travelled.

Does Puncturesafe contain toxic ethylene glycol anti-freeze?
No, it uses a non-toxic, environmentally friendly anti-freeze substitute. It has a preservative for increasing tyre life and retreadability - and it's almost odourless.

Will Puncturesafe rust or corrode wheel rims?
No, nor a tyre's steel belts should they become exposed.

Can Puncturesafe be easily removed from tyres?
Yes, the water-based gel can be hosed out or wiped out with a cloth. And it doesn't bond to the inside of a tyre, so allows retreading.
