Long lasting, skid resistent tyres?

sounds ridiclous but I live in a pretty hilly area and it's much less effort not using brakes.

You are right, that does sound ridiculous.

In fact, I will go one step further and say it is complete nonsense. I can't imagine that it is physically possible for you to exert less effort using your legs to brake than it is to pull a lever with a couple of fingers, even though I am no scientist.
