Is Singapore Puncture city?

Postby QRM » Tue, 26 Jun 2012 12:24 pm

I read Indonesian scumbags tire shops go around chucking nails on the roads the local police have a special magnet to clear the tarmac.

I have been in Singapore (6 years) and had 7 punctures already.

Is it OK to patch the tires or to avoid high speed blowouts damaged performance cars tires should always be replaced? Is paranoia getting the better of me?

If one is punctured should you replace a pair or is that tireshop BS?

Do you mean tyre punctures? :P

There is a British Standard for tyre repairs (dunno about any other country), which specifies that:

* can only patch if puncture is within the tread of the tyre (not the shoulder or side wall)
* repair must be done from the inside (inspecting for damage) with a plug AND patch (or a combo plug/patch piece)
* repairs cannot overlap
* I think high-performance tyres can only be patched once IIRC.
* Tyre should be serviceable in all other respects (google the BS if you need more info)

Done correctly, a patch will perform as well as the original tyre...but I haven't found a tyre repair place in Singapore that I trust YMMV.

If you're looking at replacing tyres then:

* the common rule-of-thumb is replace both tyres if the tread difference is great than 30% on the worn and new tyres (i.e. if the new tyre tread is 10mm and the opposite tyre not being replaced is >7mm, then you're ok. If its <7mm its not OK
* if in doubt, replace both tyres and keep the non-punctured tyre and use it for your next puncture :D
*sometimes you can match one new tyre with the "new" spare tyre, and move the part-worn to the spare wheel.
* If replacing one tyre, it should be the same make/model as the opposite tyre, the only difference should be tread depth.
*if you're talking front tyres, and notice any pull to one side under heavy breaking, go back and replace the worn tyre too.

why do I remember this shite?

Not quite sure what a "tyre" is, but assuming curiousgeorge just has a faulty keyboard, his advise looks good for tires :lol: :P

This site has some good explanations on tire repairs along with nice graphics:

I've had two punctures in five years in my z-rated tyres.

So far I've been okay with them putting the plug in from the outside..... you know, where they squeeze in glue paste and leather or some such thing into the hole with a braddle. First time I saw that I was nervous like hell getting back up to speed but I have to say, works well.

I only had my tyre fixed one time in a proper way out here, that was with my KL car, again z-rated, just off the N-S highway somewhere after i picked up a puncture in the petrol station or slip road. There, he took the tyre off the rim and patched it from the inside.

Hey, Oxford English Dictionary says this:
tyre |ˌtaɪ(ə)r|
noun
British spelling of tire2.


It doesn't say:
Tire
American spelling of tyre.

:P :cool:

Two punctures in 7 years in my motorbike (an unidentified piece of metal and a screw). Fixed with this self vulcanizing rubber thread applied from outside. Never lasted longer than one week but without any catastrophic failure.

OK so lets call it the black rubber doughnut bit of a wheel, here a real scenario that happened to a friend.

She was in friends car when they got a flat, the garage said the black doughnut bit needed to be replaced. Driver was short of cash and asked them to patch it up. A few miles later doughnut blows out car rolls two people are killed, one of them being my chum. My chums family get the police report and is suing the driver of the car for causing death through negligence as she patched the black rubber stuff rather than replace it.

If you have a crash here would the insurance firm slime their way out of paying because you did not replace or correctly repair the black doughnut?

I would argue that she is not an expert and this is not a common sense that patching a tire may lead to such a catastrophe. One exception: if she was informed about potential consequences/hazards by the repair shop.

That was the crucial bit of info the garage did tell her to replace the tire and witnessed by her surviving friends. The garage made a big issue about having told her not to patch the tire obviously to clear themselves of any blame.

I would say it depends on two things not present in your story:

1) How badly damaged was the rubber donut? Was it in the tread or the sidewall? Did the damage fall within the guidelines posted previously?

2) How fast was the friend travelling and/or under what road conditions? I've been in high speed blowouts at ~75mph in the US and while unsettling was not close to a catastrophic loss of control.

To answer your question though, I woudln't put it past a Singaporean insurance carrier to try and slime their way out of anything.
