Car Tyre Sealant? Contiseal?

[DickP]

Hi,

I am familiar with tubeless tyre sealant setups for cycling, and had understood this was never applied to cars because of it being a liquid making balancing a problem and also drying out (as it does with bikes).

I have now just seen that Continental are marketing Contiseal on a few of their tyres, which is supposed to be a sealing system to protect against punctures up to 5mm. Does this actually work? Do the tyres behave like normal non-Contiseal? Anyone got experience of it?

Thanks,

Conti-seal has been around for a lot of years now.

It is a kind of inner puncture-proof layer inside the tyre.

Has a set of SC4's (or maybe 5s) with it about 8/9 years ago.

Didn't have a puncture, so can't comment on its effectiveness.

So if you got a puncture, you would have concluded that it doesn't work. But since you didn't, you can't conclude that it did work. Or can you?

I've never used it, but I've read positive comments about Holts Tyreweld which suggests it is easier to clean out for a repair than other similar products.

A quick Google has one person say that they are £20-25 more expensive per corner. Another guy said it failed to seal the a puncture less than 5mm.

If you're the people that like to call the AA out to change a flat tyre then these will be perfect for you.

I'll stick with the £10 Amazon tyre plug kits that I have in each car - not only can I plug my own cars, but that of anyone else stranded.

Or maybe you did and it works.

I can 100% categorically state that they definitely fend off Lions though as I NEVER saw one when they were fitted.

See above answer.

I can honestly say from experience - not in my car, but the car I was travelling behind - that 3 cans of tyre sealant and 2 packs of tyre string will not seal a 4" gash along the sidewall of a non-runflat tyre when you're in the middle of nowhere on part of the NC500 route.

It will also not help that driver in having to drive 3 miles (we were up near Torridon/Annat on the way to Applecross) to get a phone signal so they could call the AA.

Luckily we passed a country house hotel as we searched for high ground for a better signal, so as the tyre was already ruined he drove slowly to the hotel and stayed in their lounge to wait for the AA. Unfortunately he couldn't stay overnight as it was booked out for the weekend for a company retreat.

It also failed to keep the wild haggis at bay, as I'm sure I found one trying to eat its way into my car via the front brake duct.
