Re: WOW ! I thought I was on my own...
This is what I love about the internet. Information is available worldwide; without being told either about Schwalbe or Continental, I wouldn't have had a clue where to start looking for legal rubber.
Incidentally, although I wasn't going to use it anyway, the dB rating it on the side of a strimmer engine I have. 112. The VOSA requirement is 91, and my understanding is that every 3dB increase is actually a doubling of the volume of the original number. This means that it's a very poor starting point for transport in Britain.
