Active Road Noise Cancellation technology

[Rhodie]

Surely this isn't correct, a puncture ie screw in the tyre cannot be fixed, new tyre is required at a cost of £300. My 2018 RRS has these Active Road Noise Cancellation technology tyres which cannot be repaired. Crazy!

Repair it - see how it goes

If there's a huge problem then replace

Seems better to risk £20 than splash out £300 in the first instance

Worst case , repair the tyre and sell it on as a spare on Ebay

What tyre is this?

[LooneyTunes]

Have they changed how it works?

This press release makes no mention of specific tyres: https://media.jaguarlandrover.com/news/2020/10/new...

Is it the dealer, the likes of KwikFit, or an indie telling you it can’t be repaired?

Could be referring to Acoustic tyres, which have a foam ring bonded to the inside of the tyre tread to reduce resonances from the tyre. You can therefore see why these can't be repaired in the traditional manner...

Aye, these (Pirelli Scorpions) are on my frau's RRS but they're not really active, they're passive. Curious to know what tyre the OP has.

[Rhodie]

The tyres are Pirelli Scorpion 275/40 R22. PNCS noise cancelling sign is on the tyre.

They're not 'Active', it's just foam glued to the inside of the tyre. They can be repaired (you just cut out a section of foam and pull it off) but finding someone who can be arsed to do it may be more challenging. Not unlike the great debate about repairing runflats, they can be repaired but finding someone to do it is more difficult.

Here's one I made earlier:





And this is what a repaired one looks like, to give you an idea of what goes on inside:





For the avoidance of doubt, I'm not a tyre bloke, I just had the top (broken) one knocking around and the repaired Continental is one that came with a car I recently bought.

Thank you Spleen, yes that is exactly what happened to my tyre, but they would not not fix the puncture.

I often find that independents are usually more willing to do stuff like this rather than the big names as they prefer you to spend money on a nice new shiny tyre. Who refused to do it?
