Is anyone using IRC knobbly tyres on the front for dualsport use, ie offroad and tarmac. I hear they're good in sand/mud but a bit soft/unstable on hard surfaces. Some people tell me they're only unstable on hard surfaces for first few hundred kilometers, but settle down after that. I have been using the more expensive Dunlop knobbly on the front to date. Its a good tyre but doesn't have much meat on it from new and wears down pretty fast, imo.
