Re: new tyres...
The mould is sprayed with a mould release oil/agent to stop the tyre sticking to the mould as it cures. This means your new tyre is covered in oil, which is why you have to ride carefully for 100 miles, especially in the rain! :-/
However.
Take said new tyre-on-wheel and scrub the tread with warm soapy water in a suitable receptacle (bath)
When you have scrubbed all the way round, rinse it off (with the showerhead)
The tyre will now be devoid of anything oily and safe to use from the start!
Rubber itself is quite delicate, containing many oils and minerals in its bulk - do NOT (FFS...) use brake cleaner, petrol or WD40 to clean your tyres off. It will NOT be good.
