why don't grooved tyres get better grip as they wear?

this may be a stupid question, but I've always wondered why they don't get better grip as the grooves disappear. I know the FIA has a rule saying they can't get better performance from this by design, but it seems to me that more rubber contact = better grip any way you look at it.....

can someone please explain this to me?

thanks in advance

This could be controlled by using a different compound for the substrate upon which the treads are moulded.

Another BIG factor being overlooked is that the tyres don't wear out evenly. Actually, the outside of the tyre tends to go off first, so what you have is a tyre that is not flat. That is no good at all!
