I’m a huge fan of run flat tyres Chris. I had them on around half a dozen BMWs (3 and 5 Series) and they were brilliant. Whenever I had a puncture I could just carry on as normal and get the tyre changed at my convenience. Unfortunately, ‘enthusiasts’ and motoring journalists constantly harped on about them causing a harsh ride quality and extra road noise (neither of which I ever even remotely experienced) so they now don’t fit them as standard any more. Self sealing tyres (as used on the Tiguan) are very different. Unless they’ve changed them to run flats, the ones we had on our last Tiguan were the self sealing ones where they supply a canister that allows a temporary fix until the tyre is changed. It’s not a good system and makes a right mess.
Not 100% accurate, yes they are self sealing on the Tiguan, but the canister you are talking about is the puncture repair kit. The self sealing Continentals the car comes with (mine still has the original ones from factory on the rear, coming upto 5 years) have a layer of ‘gunk’ which seeps into holes if the object has penetrated all the way through and if the object is removed and the hole small enough, the ‘gunk’ will seal that hole.
Self sealing tyres can be repaired, I read a manual from Continental on the repair process, but it takes much longer than a normal tyre because the ‘gunk’ lining has to be replaced, so all round cheaper and quicker to replace.
Humanity is only humanity when all are treated the same regardless of their skin tone, religious beliefs and geography!
