Foam filled / non foam filled tyres

[LEE3]

Has anyone switched from the standard foam filled tyres to non foam filled and noticed any significant increase in road noise?

I’m assuming all M3 tyres which come as standard with the various versions are foam filled so just wondering if anyone has switch to a non standard tyre and experienced an increase in cabin noise.

Hard to say ... I had winter tyres without acoustic layer, so not a direct A/B comparison. The winter tyres were a bit noisier but I would have expected that due to the tread design and depth anyway. There's bound to be some degree of benefit from the sponge layer or they wouldn't specify it. (It's just a strip of ¾ inch sponge, as wide as the tread and stuck to the inside ... I wouldn't exactly call them "foam filled". I suppose I'm on a bit of a crusade over this "foam" description ... it's sponge ... like you might use in the bath!)

I don't think most model 3 over here come foam filled - my dual motor (so non-perf.) came with Michelin Pilot sport 4 so non foam. May have dropped it for UK now

Have you seen inside them? My Michelin Pilots certainly have an acoustic sponge lining.
