Got it. So it uses the same clamp type like the bicycle foot pump. Hmm, that thing is quite clumsy, so i know what you mean that it comes off easily

This cap, not the nozzle. So far I have not had any issues with the nozzle, other than it having a rather bad design which can pinch the skin, if you use the entire palm to press and lock the nozzle in place

Oh...you mean the top cover of the case, I thought the nozzle thing haha.

What do you intend to do with the pump? Inflate the tyre after patching it up yourself or inflate it to get you to the nearest tyre shop? If it's the latter, if the leak is bad enough to flatten the tyre (nails usually cause very slow leaks), a pump won't help much.

Do take note that for regular topping up of tyre pressure, you don't need much volume - I use a bicycle hand pump for that.
To inflate flat tyre, you need a lot of air so make sure to research and ensure whatever cute pump you buy can deliver that much air continuously.

To inflate the tyre temporarily after puncture. I agree with you, so that's why need to ensure the electric pump can do the job. I am also looking to get a DIY patching kit for good measure.

I'd also buy a manual bicycle pump as a backup and for peace of mind. You can use it to let the electric pump cool down.

I put a high volume bicycle hand pump at boot, together with a few cacing to plug the hole.

It’s as reliable as it gets, maybe need 60-80 strokes to get from 15psi to 30+, while it’s indeed alot of work, but if it’s emergency, better then nothing.

Also, I dont worry about inflating from a complete flat, as in flat until rim touch floor flat. If your tyre reach that stage, you are either a completely shit driver to not notice tire pressure dropped below 20 (since i know not everyone have tpi) OR, your tyre suffer a blowout which means whatever eletric pump u got also no use la, just call the insurance free towing la

If tyre completely flat then you need a combination of tyre foam filler repair kit and electric pump. Just need to be careful if you are going to invest into these foam. Cause I read it will destroy your tyre in the long run. So you need to change the tyre after using those foams. However, there are some brands that claim will not damage your tyre and you can continue to use it like normal.

if my tyre completely flat, it means there's been a massive blowout or sidewall tear, or some huge hole already la (ie.NOT FIXABLE VIA ROADSIDE, unless you still have old cars with spare tyre/non-contis). You would be so dumb to let your tyre slow-leak(fixable via gel/foam/cacing) until completely flat.

fix-a-flat/foam only works for smaller punctures like nail sized ones, and yes those will throw off your tyre balancing and it's just not worth the hassle of removing your tyre, getting it cleaned at the workshop, and get a proper inner-patch(permanant) to fix your tyre.

The only reason i need an eletric pump is because lazy, and there is a chance of it spoiling. I much rather trust my fully mechanical, simple handpump with minimal moving parts.

Due to some sudden turn of event, ended up with a new set of run flats again. So the need for the electric pump diminishes, but will probably the the lite one for its gauge and minor inflations. Will keep this thread open as there are some good sharings by forumers which can benefit those looking for the same thing. TQ all.

Tough luck, tyre got punctured by this brake pad metal laying on the road. Pressure dropped to 30kpa within seconds and don’t dare to drive further despite being RFT. RM1k+ gone just like that because of tak apa attitude. Now need to wait few more years to change to non-RFT as only changed a single tyre.

sorry about your tire
everyday I drive with much worries, looking around for debris on the road
i wonder how something flat like this can poke itself into the tire? Does the rotation of the tire kicks it up? Will driving slower helps?

I tried to review my dashcam but not able to see the metal on road. Drive slower would help I supposed. Was driving around 60-65km/h. The tyre shop said maybe my front tyre went over it, then it bounced and got hit by the rear tyre. That's why it pierced deep.
