It's increasingly common to find a can of tyre sealant being supplied in a new car instead of a full size spare wheel?
But are they really an effective substitute? If you've had a puncture and had to use a sealant because you had no spare, how did you get on? Quick, effective fix or complete waste of time? |

I've recently used some and i have some information with regards to the Holts Tyreweld post-puncture sealant product. The formula itself I'm told is a water based latex emulsion foam (water based rubber), so there are no chemicals which affect the rubber of the tyre, the rim of the wheel or anything else which is good as it meant the tyre was repairable under British standards. So when I took it to a tyre repairer all they had to do was wash the sealant out of the tyre with warm soapy water and apply the puncture repair plug/patch.
I think post-puncture sealants are a very good idea, as they limit the amount of time you are stood in the road (in the danger zone) sorting out the puncture. With Holts tyreweld especially this is good, as the system they use on their product you can just remove the item causing the puncture, rotate the tyre so the puncture is at the bottom and in contact with the road surface, then connect it to the tyres valve, turn it on and then retreat to safety while the foam goes into the tyre over a couple of minutes. There is also no need for a tyre jack or any particular tools, so it also saves the space of the tyre jack and tools along with not having to carry a spare tyre. From my experience I believe the product works effectively, Holts recommend a short drive immediately after applying the product to the tyre, I'm told this warms the foam which helps it to seal the puncture, the drive also apparently increases the pressure in the tyre as the foam expands from the heat which also helps with the driveability of the vehicle. |

My experience of these sealants is very negative. My wife bought a new Tigra and within a week she had a major problem, hitting a piece of wood on the motorway. The tyre sealant was useless as the alloy wheel had a large hole in it as a result of the impact!
On the second occasion a simple nail in the tyre proved totally frustrating. I followed the instructions on the tin and removed the offending nail, then injected the sealant. I watched in amazement as the foam came straight out of the puncture site! What a waste of time and not an insignicant amount of effort. A spare wheel could have resolved the situation on both occasions. I am seriously considering getting a spare wheel and tyre and leaving in the garage for any future situation. |

I have used tyre sealants on 3 occasions for just a puncture and it has worked fine. The latest time has lasted a year so far and the tyre loses less pressure than the other tyres.

I watched a police camera action video once where the police were chasing a stolen car, the police car got a puncture and sped off the road! The commentator said from now on they fill their tyres with foam to prevent them from getting a puncture and so do I now on my motorbike, not had a punture yet on the bike, but hope this isn't just good luck.And army vehicles used this stuff in the war, providing it isn't a big cut it works ok! but it's still reassuring to have a spare in the boot though!

Sealants aren't intended as a permanent repair - they're only a quick fix to get you home.
You really should get the tyre repaired or replaced as soon as possible after the original puncture otherwise you risk another, possibly more catastrophic failure. |

I read tyre manufacturer literature a year a so back, and it stated that tyre sealants are not a legal method of tyre repair. A damaged tyre needs to be removed from the rim and inspected inside and out for the extent of the damage, and then repaired with an approved vulcanised patch that is applied with professional equipment and material, if it is assessed to be safe enough to do so. The presence of gummy goo makes this job more awkward for the professional to do. Plugging puctures with do-it-yourself kits is also not seen to be advisable, although cheap and convenient.

I have used Tire Sealants but that pressure is reduced slightly ko do ------------------------------------------------- may tinh xach tay | laptop hp | laptop apple |
