Contrary to belief and expectation, ULTRASEAL is not a miracle cure for every type of damage that a tyre can be subjected to. ULTRASEAL permanently repairs a hole in a tyre that has been cleanly penetrated by a nail etc, and then quickly removed before any internal damage to the cords or rubber occurs.
ULTRASEAL is guaranteed to work 100% when the puncture is straightforward, as defined above, and which is generally the situation in 95% of punctures today.
If a tyre that has been treated with ULTRASEAL is going flat, it is important to visually inspect the wound for the following:
HERE ARE LISTED SOME OF THE PROBLEMS THAT MIGHT ARISE:
IF ONLY AIR IS ESCAPING FROM THE WOUND.
1. There is insufficient amount of ULTRASEAL in the tyre. This could be because insufficient ULTRASEAL was fitted in the first place, or the tyre is very porous, and therefore a large proportion of ULTRASEAL has been absorbed into the tyre. Porosity can be caused by a very old tyre, or a tyre that has been run under inflated for a long period causing the inside area to have an excessive amount of tiny cracks and holes.
2. The wound is too large and all the ULTRASEAL and the reserve have bled through the wound.
3. The tyre is too old and the rubber content has lost all elasticity. Therefore, the wound will not have any recovery. Rubber recovery/elasticity is very important for ULTRASEAL to function. As a puncturing object is removed from the tyre, air escapes and the wound closes (rubber recovery). ULTRASEAL has preconditioned the inner surface of the tyre and is standing on guard for any air loss; at this moment ULTRASEAL rushes into the wound just prior to the recovery and the synthetic fibres with their special Velcro like surface, collect, and key together to form a dam (log jam). The rubber around the wound is what holds the ULTRASEAL repair clot in place.
IF BOTH AIR AND ULTRASEAL IS ESCAPING FROM THE WOUND.
1. The damage to the tyre is too severe and potentially dangerous.
2. The wound may appear small but the cords and internal structure of the tyre has been damaged and the tyre must be taken apart and inspected. Usually caused by a large rough nail or glass etc., which squirms about whilst the vehicle is in motion, tearing and ripping at the rubber and the cords until the hole is enlarged. Sometimes the hole may look small, but there may be a large cavity of damaged rubber and cords behind that small hole, so there will not be sufficient tightness in the rubber to grip the escaping fibres, but the driver will have experienced a controlled deflation.
Do not expect ULTRASEAL to seal a potentially dangerous wound, such as those described below:
1. Cuts/slashes by glass or other large objects - this type of damage will cause extreme structural damage to the tyre. ULTRASEAL can not, nor will not, hide or mask any dangerous wound, regardless of size.
2. Nails that have been in a tyre for long periods will have a negative effect on rubber recovery. The rubber around the wound will temporarily lose its ability to recover. It is as if the rubber has gone to sleep and needs to be shocked to reawaken (to recover). If the tyre/rim is not mounted on the vehicle when the puncturing object is removed then we suggest striking the tyre with a mallet several times around the wound, to flex the area, thereby reawakening the rubber and also shocking ULTRASEAL into the hole. If the tyre is mounted on a vehicle simply drive the vehicle and this will sufficiently flex the tyre.
3. Any split, tear or sidewall puncture may very well cause damage beyond ULTRASEAL’s ability to provide a secure repair because of the lack of rubber recovery. At best, only a temporary repair is attainable and only because ULTRASEAL can not mask a potentially dangerous wound.
4. When removing a screw, always use a screwdriver or a tool that will allow you to rotate the screw out of the wound without causing additional damage. Pulling a screw out of a wound would rip the tyre’s inner structure and may ruin the tyre.
WHEN ANY OF THE ABOVE HAS HAPPENED, ULTRASEAL WILL HAVE DONE IT’S JOB AND THE DRIVER WILL HAVE EXPERIENCED A CONTROLLED DEFLATION, AND POSSIBLY ALLOWED HIM/HER TO FINISH THE JOURNEY.
On rare occasions it has been known for a tyre to sustain a little air loss before ULTRASEAL permanently sealed the hole. Correcting the air pressure after inspecting the tyre is the solution.
Sometimes air loss can be ongoing in a punctured tyre because the puncturing object is positioned in such a way that it will allow a little air to escape with every revolution of the wheel as the object comes in contact with the road. Remove the object and correct the air pressure.
HOW TO IDENTIFY A HOLE THAT HAS CORD DAMAGE?
Without cords, a tyre will blow up like a balloon, it is cords that keep the rubber tight. Whenever cords are damaged within a punctured area that particular area will expand with increasing air pressure, causing ULTRASEAL to just blow through until the air pressure becomes much lower enabling the fibres to log jam in a smaller hole. (controlled deflation).
With the tyre off the vehicle, bouncing the tyre with the hole on the bottom should throw ULTRASEAL towards the hole. To identify if this hole has cord damage set the tyre pressure very low and ULTRASEAL should stop the air leak, assuming there is still sufficient ULTRASEAL in the tyre. As you increase the air pressure the damaged area should open wider and wider with ULTRASEAL and air blowing through the hole and only air blowing through at high pressures. This is a good indication of internal rubber or cord damage. If you cannot get a good air pressure into a tyre with a decent size compressor, then it is a good indication of a dangerously large hole that is expanding with increasing air pressure. When cords are severely cut, the hole in the tyre will enlarge with increased air pressure, so in a moving vehicle ULTRASEAL will assist to give a controlled deflation as the hole shrinks with air loss and reducing air pressure. With ULTRASEAL, and a controlled deflation, a tyre will deflate at a rate depending on the extent of the damage, then as the tyre reaches the lower pressures of 10 to 20 psi, a severe slow down or halt in air loss will be experienced as ULTRASEAL is now being log jammed in a wound that is now shrinking in size because of these lower air pressures.
The driver will now be running on a very soft tyre instead of the wheel rim, which could mean the difference between keeping control or losing control.
This is possible because ULTRASEAL do not use chopped up slippy rubber in our formulation, we use 5 different sizes of specially manufactured "course surface" synthetic fibres, stronger than steel, which interlock together like Velcro.
A wheel arch that is covered with ULTRASEAL, is a good indication that the tyre has experienced a controlled deflation.
It is better to remove every nail you see in a tyre, but natural forces will remove them eventually. Large ones should be removed as soon possible, and near to a supply of compressed air if possible, in case the air loss in a stationery vehicle is excessive. A slight tap with a hammer to the area above were the nail is being removed will shock ULTRASEAL into the wound as the nail is removed. Centrifugal forces when the vehicle moves will do the rest. If the hole is not excessive, but you lose all the air in the tyre after removing a nail, just blow it up to the correct pressure and quickly drive a couple of hundred yards to allow centrifugal forces to throw ULTRASEAL into the hole. If you get a flat tyre after ULTRASEAL has been installed, it may indicate either you have got a puncture whilst parking up, not giving ULTRASEAL chance to work, or there is a large puncturing object that allows air to escape with every revolution of the wheel as the nail hits the road. Just remove the nail following the above guidelines, correct the tyre pressure and drive on.
How to repair a PUNCTURED tyre with ULTRASEAL
ULTRASEAL can be used as a repair method on tubeless tyres. If the tyre personnel inspects the damage, and is assured that the wound is caused by a puncturing object that is less than ¼" in diameter, the cords are not severely damaged, the tyre has not been run flat, and the wound is free of any foreign substance then the proper amount of ULTRASEAL can be installed. After installation, pull the puncturing object out and rotate the tyre or drive the vehicle to allow the tyre to flex. Re-air the tyre to the proper pressure. See how do you identify if a hole in a tyre has got cord damage?
HOW TO REPAIR A TYRE CONTAINING ULTRASEAL.
Tubeless tyre ULTRASEAL is a permanent repair, but in the event you may want to repair a damaged tyre dismount the tyre and wipe the ULTRASEAL away from the damaged area with a damp rag, dry the area that is to be repaired, buff and repair as normal. If the repair (including mounting and dismounting) is completed within 2 hours it is not necessary to remove the remaining ULTRASEAL from the tyre (ULTRASEAL will start to cure after 2 hours in a tyre that has been removed from the rim). Remount and add any additional ULTRASEAL that may have been lost through the wound or that was removed to perform the repair.
ALWAYS BALANCE TYRES AND CHECK FOR OUT OF ROUND WHEELS PRIOR TO INSTALLING ULTRASEAL.
REBALANCING TYRES containing ULTRASEAL
It is extremely important to understand how ULTRASEAL’s Thixogel performs (a proprietary process not found in any other tire sealant). Thixogel allows ULTRASEAL to cling to the inner sidewalls and the entire inner surface of a properly balanced and true (round) tire/rim. The centrifugal force which is created within a high speed tire actually stretches the ULTRASEAL much like a rubber band, however, it will not pull the ULTRASEAL off the inner surface of a properly balanced tire/rim. An out of round or extremely out of balance tire/rim can create enough adverse forces to pull ULTRASEAL off the sidewalls. If a tire/rim requires in excess of 3 units of weight, the tire/rim should be inspected for defects and corrected prior to installing ULTRASEAL. ULTRASEAL can not correct an existing problem and may aggravate the situation.
The proper amount of ULTRASEAL for highway speed vehicles has been calculated to provide a complete coating to the inner surface of the tire/rim, allowing for absorption into the casing and still maintain a reserve. The reserve (approximately 20% of the installed amount) is extra ULTRASEAL that will shift/move and eventually settle to the bottom of the tire after the vehicle is stopped. Each time a puncture occurs, a small amount of reserve is used and the balance of the reserve constantly redistributes as the tire rotates, thereby providing an even coating.
Any high quality speed balancer may be used to rebalance a tire containing ULTRASEAL.
It is imperative to distribute the reserve that has settled, prior to taking a reading.
1. Important – Remove any existing weights prior to rebalancing a tire.
2. To distribute the reserve, mount the tire/rim onto the balance machine and start the machine to spin. It is very important, when tightening the balance machine spinner against the tire/rim, that the cone is centered, as the slightest misalignment causes an inaccurate reading.
3. Take a wooden stick (similar to a small baseball bat) or a light hammer and tap the tread area as the tire spins (the balancer’s speed and short spin duration does not allow the reserve to disperse without repeated spin cycles and constant tapping).
4. At the completion of the third spin cycle, take a reading and place the weights as indicated. DO NOT RE-SPIN THE TIRE, the tire is now balanced and can be mounted on the vehicle.
5. Any time the balance machine is re-spun after the reserve has settled with result in an inaccurate reading and will indicate that weights are needed in a different location. This movement of the reserve is the reason you will not get a 00 reading, unless the tire/rim was in-balance initially and the reserve was properly distributed.
