tyre warning

[ade.d]

just changed from bridgestone bt45 battleaxe to bridgestone gritty tyres on my tt600r.within 2 miles of my first outing at about 10 mph on a left hand bend the front tyre went from under me,they just let go!the tyres are road legal enduro knobblies and i think are UNSAFE for tarmac use.the bike went into the other lane and i skidded 10 yards on my ass,sever road rash to knees and elbows,pulled something in my shoulder.ive had loads of bikes with allsorts of tyres and never encounted this,the road surface was fine and no sign of deisel.no damage to the bike except slight fork twist and scrathed bar end. wish id had somemore bt45,they are great for all but wet offroad.
