My ID4 has Pirelli Scorpio elect tyres with seal inside. Unfortunately I have a nail and it is slowly leaking air. It is right in the middle of the tyre and it seems to be a relatively long nail. Do I simply pull out the nail and the seal inside should work? Do I need to further replace the tyre if the seal inside does work anyway?
All advice appreciated.

You should not pull it out, the hole will be too much for the seal inside stuff to do it's job. (I've had the same on my ID.4 with Hankook tyres). Leave it in and take it to be repaired if it really is in the middle of the tread. Check with the tyre shop before going they will repair this type of tyre, as many CBA. They need to remove the seal inside away from the repair area to get a good repair and that's a load of work many cannot be arsed with. Some tyre shops will tell you these tyres cannot be repaired, but I believe this is not true if they put the effort in. Obviously if they need to spend extra time cleaning up the repair, expect to be charged a bit more but it should be cheaper than a new tyre.

Thank you. Just out curiosity, anyone know what can the seal inside stuff repair?

In complete 180 degree advice, the nail can be pulled out, according to Pirelli anyway.

It will lose some air, but the seal layer should move to fill it.

Well you live and learn. My experience with the Hankooks was it went down.

Yeah, I think it depends on a few variables.

I had a Bridgestone on my ID.3 with self seal, and it initially did start losing air after I removed the screw that had punctured it, but a quick drive around the block and it sealed itself.

I did mean to take it in for a repair at some point but it was holed in a repairable area (the seal lining only covers the repairable area anyway) and never lost air again after being re inflated to the correct pressure, so I guess did the job. 👍

I will still call around to see who will repair these seal inside tyres but I guess there is nothing to lose by trying to pull the nail out and see what happens.

Forgive me if I'm misunderstanding this, but what's the point of a self sealing tyre if you can't have the confidence for it to ..... self seal?

Pull it out and then bill pirelli for your time and repair if it doesn't work.

Tyre snot works by blocking the hole as you drive.
My understanding is you reinflate, pull out the offending item and drive away slowly, reinflating the tyre a couple of times if needed.

It's the motion which helps the hole seal up.

It won't work with a nail sticking out of the hole which is subject to move around as you drive.

Some like the idea, some don't but I've seen people whining that it didn't work when they had a 2 inch gash down the sidewall so I guess it's commonly misunderstood.

It was a screw not a nail and about an inch long. Today I inflated the tyre to as much as I can (it was leaking where the screw was), pulled it out, moved the car to and fro a bit to push the seal inside gunk into the puncture. The tyre subsequently inflated fine and I took it around the block a few times to make sure the seal inside is in the puncture hole. So far so good.
it’s magic when it works!

It’s not really ‘tyre snot’ per se, sloshing about in the tyre, it’s a sort of vulcanised mastic that sits in a layer around the inside of the treaded part of the tyre.

screws are probably more likely to leak if you think about the thread. Glad it's sealed.
There are kits available with a rubberised glue and a soft rubber strand and a couple of tools.
People have mentioned them here a couple of times but they are easily found on Amazon or eBay.
I would be tempted to try one of those if the tyre snot didn't work too well.

That is so much better.
Is that something built into those specific tyres or is it added by the vehicle manufacturer?
Self sealing without the mess, I'd rather like the option on any car.

A few years ago "a gentleman" in a road I use daily was doing some work on a car transporter, in the snow.
I picked up a couple of offcuts of metal which were basically like stabbing the tyre with a knife.

Thankfully I'd already had a bit of wear from the tyres but going back to the tyre place a second time in the same week wasn't fun and it was only on the second visit they showed me what had screwed the tyre.

All this new not snot, tyre snot technology might not have stood a chance but it might have bought me a bit of extra time rather than stopping half way to pump up.

You have to have a run of bad luck once in a while, that was one of mine.

On the Oponeo website they have a list of manufacturers who make self sealing tyres, I’ve tried the Bridgestone ones, and they worked as advertised, and have the Pirelli’s on my current EV, but fingers crossed I won’t need to test them out!

That's great, thanks.
My guess is the need for something that didn't destroy tpms sensors lead to these but I had not heard of them before now.
If they could have those on all cars as standard we'd all be a little safer. That and runflat.
