i tried a irc m5b for the first time yesterday and the traction seemed excelent as i would expect from a brand new soft terain tire in the sand but i spent the later part of the day in hard pack with some rocks the traction was still very good and i was really abusing the clutch on my 2002 cr250 and the tire bearly rounded the knobs the slightest bit it still looks new with sharp edges i usuly run the dunlops (752 756 773)and i must say so far i like it traction seemed the same as the 752 in the sand but the m5b seemed a little better in the hard stuff. it had a more predictable slide to it in the corners than a 752 kind of like the 756 but better in the sand than the 756 best of all it wears like iron so far.this tire has HUGE knobs very tall and thick.i usaly run the popular tires (dunlop,bridgstone,ect)but as long as this tire holds up like it did yesterday i give it a thumbs up :thumb:
