And different brands medium will all be different. So there is no generic soft, medium etc etc Some soft tyres might grip worse than others medium. Some can be too soft, they get tore up and end up useless.
The Tyre Reviews site does have some great tests, and results. And it really does seem that for road use, the UHP tyres make far more sense than any track tyre. And in some cases, might even be better depending on the actual usage and conditions.
Likewise some are utterly dangerous on the road like some Michelin Pilot Sport Cup2's that it would be almost impossible to get enough heat in them on the road to get any grip.
