Title: Tyre repair gunk?
Post by: bobmax on September 20, 2017, 03:15:21 PM

I've never had a puncture yet thank God, so never needeed to use the crappy gunk I have instead of a proper spare.
I'm ashamed to say that I have not learned how it works  :-[

Has anyone here used it yet?

I'd love one of the PROPER spare wheels Mazda do, but it's so expensive. >:(

Hi! Being new to Maz3 ownership the one thing I'm not comfortable with is the lack of a spacesaver.
I rang my local Mazda dealer and they assure me Mazda do not supply one for my particular model so my only option is to carry a full sized standard wheel which will cost me around £130 + the cost of a tyre.

£180 all in - main dealer sourced alloy rim + tyre, but the long term relief now of having a "proper" full sized spare wheel will make it worth it in my case.
Let's face it - every puncture repaired with tyre gunk will cost £50+ to replace the tyre anyway and I will now no longer have the possibility of getting a flat which can't be repaired with it at the side of the road and then having the added expense of getting the car collected.
Natch has reduced the space in the boot but mostly that can be got around.
Why don't all cars these days come with a minimum of a space saver?! Even my MK2 Scirocco in the 80's had one.

Weight saving leading to improved economy and a reduction to On the Road cost.  Well that's what Mazda says.  Having said that, I have an unused space saver as OEM in my Gen 1.

I agree that manufacturers say that the weight saved by not having a spare wheel  improves fuel economy. To a certain extent this is true but also a load of tosh. A hybrid is fitted with an additional battery and auxiliary equipment which all adds weight and reduces fuel consumption which may or may not make up for the hybrid in the first place. Hydrogen fuel cell is the only way to go long term. Aren't politicians bright enough to realise this? I tried to buy such a car but with 3 filling stations in the UK so equipped in mid 2016 it was a no no.

Not to mention the incredible waste of resources if a puncture can't be mended by the side of the road.... calling out a recovery truck etc.
Madness. Such is life today - Halfords offering a bicycle puncture repair service...I could mend my own punctures when I was 10 years old!!
We could all build a trakky bike from junk at 12 y/o!

Must be a good few wrecked 3's kicking around by now. Why not try the breakers, get a full wheel or even a second hand spacesaver? Yes I know you'd need to put some foam or something under the boot liner with a full size.

I've had two flats in my time; one the boot gunk probably would have done, the other was with a full car load, and I mean to the roof passenger, rear and boot just outside Stranraer at 5am on a Sunday. I seriously doubt the gunk would have got me to Dumfries... spacesaver would have taken all day; thank goodness for the good old days of the full size spare.

... and to answer the question I believe you just attach the presurised can to the valve as usual and squirt (it'll inflate the tire too if the hole/flat's not too bad). Nothing to worry about... other than it not working...

Yeah, I did buy a second hand wheel + tyre a while ago, but had to put it between the front & back seat. It's is very large.
I needed the space in the boot/hatch for suitcases when traveling on holiday.

To be fair, I haven't had a puncture in the 3 years I've had it, but sods law and all that  ::)
