got dakars on my 90. most times they can plow through mud i cant walk through lol, but once the treads fill up, thats it, no grip left. they do allow the motor to slide sideways on side slopes and dont have much of a shoulder, i found myself stuck in ruts a few inches deep, the tyres just refused to climb out. road use well they seem to do ok, seem to run fairly well. they are cheaper yes so maybe not as good as premium brands but if you were to rip a sidewall open on a rock they are just scrap rubber whether they cost ?70 or ?170. id rather pay ?70 myself lol.
