Another long EV tow.

This is the version I had in mind:-

There are plenty of alternative vides's available.

Interesting. However sometimes it is difficult to determine where the puncture is located unless the wheel is removed.
Recently the fitter pulled what looked like a nail with no head out of our caravan tyre. The head was not worn off. That was the way the spike was made. The tyre actually had two nails in it, one I could see as it had a head and the other was basically invisible.
Can you use this stuff if the nail is still in the tyre or will the seal break as the tyre rotates moving the nail around?

I have the Conti kit in my EV, and it was in the PHEV before that. But for me it would be an absolute last resort - only if there was no chance of me getting recovered and missing a flight or boat as a result. The tyres on the EV are about £280 each, and are a Polestar specific specification. They can be repaired, but only if the gunk has not been used. Effecting a true repair would be the preference, and should be just as strong as the origional.

The reason i converted my last Forester to a full size spare was in case I got a non reparable puncture which may have required all four tyres to be renewed in order to maintain the Fwd tread depth variation within specification. So the FSS was a part worn tyre that had never been repaired on an OEM alloy wheel, and it did the job one Bank Holiday in north wales. But I still had to shell out for a brand new quality tyre to replace it with as the tyre depot had no budget or mid range in my size. But on selling the car I recouped the cost of the alloy and tyre via EBay.

Looking at the Continental video I posted you do not need to spot where the puncture is. That’s why you insert the sealant, pressurise the tyre and drive a short distance then recheck pressure. The Sealey video doesn't require re pressure of the tyre but it’s speed is limited to 30 mph. Whereas OEM kits are okay for 50 mph and a good distance. You shouldn’t attempt to remove the nail as this is already tending to seal the puncture, and doesn’t having to remove the wheel defeat the object of the sealant/ inflator procedure, which in any case doesn’t come with a jack from the car maker.

I converted our 2017 Rio to a space saver with jack and the sealant kit is in the loft. No need to check dates on sealant for expiry.

I believe that cars that cannot carry a spare have to have a tyre sealer and inflater system. often its a one piece aerosol canister.


I pretty certain there isn't any regulation that prevents manufacturers from considering using spacesaver spare wheels on EV's. But its possible that there are no suitable tyres with the required load ratings for some of the bigger EV's.

But the reason the spacesavers came into being was to save space and weight of a full size spare. This was mostly driven by manufacturers striving to reach better fuel consumption.

I doubt the load rating is an issue - my Touareg has a space-saver spare, capable of taking it's share of the nearly 3 tonnes MAW.

.I’ve yet to see a sealant kit supplied by an OEM that uses an aerosol as the injector and pressuriser. The one shown in your video is Sealey and an aftermarket purchase. All the OEM ones I have come across have a sealed bottle of sealant and a 12 volt powered compressor. The compressor injects the sealant whilst pressurising the tyre. It also provides a fall back in so far that the compressor can be used to re inflate the tyre should a slow puncture still be present. Also the OEM supplied kits allow 50 mph driving speed, with distances of up to 120 miles. What stops you exceeding 120 miles is basically a safety safeguard to get the puncture repaired
