Tyre compound differences

[rondoolaa]

Hi,

Any advice please.

What's the difference between Schumacher rally blocks yellow compound and White compound,

Which is the softer material and which would be better to use on a polished wooden floor,

I was using some on my car last night and they gripped to the wooden floor like glue but have no idea of what compound they are so I can purchase more.

Thanks for any help.
