Puncture Repair Spray
 

The car I am looking to buy doesn't come with a spare wheel (You can get one as an optional extra). It comes with a "Puncture Repair Spray". How do these work, and is it a viable alternative to having a spare wheel?

I know of a "slime" type system that gets put into the wheel through the valve stalk and then you re-pressurize the tyre.

So if you weren't near a garage to get air you would be stranded?

Re: Puncture Repair Spray
 

I believe it is a pressurised can of special foam which you squirt into the punctured tyre via the inflation valve, this inflates the tyre and the gunk in the tyre seals the leak and fills the tyre with a compound so that it can be driven to a tyre place who then repair the tyre.

AFAIK you put it in before you get a puncture and then if you hit anything the air pressure in the tyre forces the "slime" through the puncture and seals it enough to hold pressure. Did you ask what the spray was?

No, it inflates as well if it's like the one from Holts.

So it's just a quick fix to get you to a tyre place?

These are quite handy to give to members of the family. Much safer and quicker to use than changing a tyre at the roadside.

The problem would be if you have a blowout or hit something with your wheel so that the metal itself is damaged. The puncture repair spray will only work for small holes - anything more and you'll be stranded.

Yes, I had a old Citroen at one time and it came with the trash left in the boot by the previous Gitanes smoker, I did have to use it once but then I threw it away, the car I mean.

Ooo sounds like one of MGRovers cost cutting schemes to me :p:

If I was you, I would get a spare from a scrappers just incase. The repair sprays are only any good if the puncture is small. It all depends on the type of puncture you get as to wheather the spray is effective or not.

BTW - a lot of tyre repair places will charge extra to repair a tyre after something like this has been used - it has to be cleaned out before the tyre can be repaired and it's not an easy job.

Re: Puncture Repair Spray
 

With modern regulations on tyre repairs it seems that unless it's a simple nail through the centre of the tyre tread it's unrepariable anyway. I wouldn't worry to much, puncture = new tyre, so foam filler is the least of your worries.

We had to use this once in a Peugeot 106 loan car, and it did work although your wise not to go above 40mph with it as the whole balance of the car is shot.

Have the rules regarding repairs changed? I've had about 2 a year repaired for the last few years and it hasn't been a problem. It basically seems that as long as the hole is in the bit that touches the road it's ok.
