In simple terms the more runs the more worn... Each run takes a layer of rubber away making it thinner which has two consequences... The thinner rubber does not follow the surface in the same way which reduces the grip and also it has less material to absorb heat so it is more prone to over heating with further loss of grip...
Generally though none of this matters for anything other than events. If your tires still work ok then they are fine for clubbies unless you have plenty of $$ to throw around.
