Foam in tyres
 
Stumbled across this video on YouTube and wondered if any other tyre put foam in them to reduce road noise?

you could jump through the start up until they angle grind the tyre open to see it.

veiws welcome.

Strange...last time I drove a Tesla (Model S) it felt like it had run-flats. Not good on the roads round here, my Golf R32 rides rough roads better.

It was quiet though and road noise is a pet hate of mine. :thumb:

Holy fcuk. Thats some mess. Exhaust got it too.
Got to wonder what the poor sod done to warrant that being done to his car.

Couldnt they just have asked Tesla , instead all that garbage to get on air

Further thought on the tyres...it's a sticky plaster fix for a NVH issue where there is a resonant noise at motorway/highway speed.

Tesla suspension is pretty much the same ZF corner module setup found on a large Mercedes or Chrysler, which in turn is almost the same as that found on Jaguars and BMWs. Many have a flaw in that the front suspension has upper links attached direct to the body and lower links attached to a rigidly bolted subframe....That provides little isolation of road noise from the chassis, which in turn can transmit it into the cabin. The rear is contained on its own subframe cradle, but again bolted via four very rigid bushes, so again isolation is limited....Its now not uncommon to see massive heavy rubber doughnuts attached to various parts of a car to add mass in aim to stop resonance, another sticky plaster for NVH issues.

Its not just tesla that use these kind of tyres,

Some Bmw/Rolls do too,

It makes sense with BMW...they have pretty much identical suspension to Tesla and the factory fit Runflats do cause a lot of NVH issues.

Never seen even it myself, despite having a large number of BMWs in and out of the workshops.

Continental and Michelin have noise reducing tyres where they have a layer of foam bonded to the inside - Conti also have tyres with a layer of what looks like tar on the inside (contiseal) which is supposed to stop air leaking if a nail, etc goes through

Funny that Conti-Silents are only available in the sizes that fit Teslas ;)
