While it is true that the 'sticktion' of a tire is non linear with load, the 'mu' of the lining material does not change with load.

If you have high spots, they will get hot, but (ignoring fade) they will be as effective since there is more pressure per square inch of contact area if it's only contacting a portion of the total area. I say it "shouldn't" make any difference, as I'm not convinced the theory and the practise are the same in this case!
