I dont think there will be much difference between semi slicks in the dry as long as they are the same compound. The difference will be in the wet/damp, where you really wont know until you try them yourself.

What do you want to use the semi slicks for? I dont suggest you use them on the road as in australia they wear out pretty quick on the road, and when you are burning $10 of tyre every 100km just doing normal granny driving, that just isnt fun.

Doesnt seem to be any issues with kuhmos
