Dude!, don't even think of those other tires if you wore mefo's out in 4,000!
I think your high pressure might have alot to do with that. Never went over 25 with my mefo's, got just over 7,000 out of them.
Been through 2 sets already. My friend had the karoo's on his 950, probably won't see 2500miles.
Every one rides differant? The 606's I have got as little as 2500 out of.
Again, if you wear out your mefo's in 4,000, sorry but your screwed. I have tried alot of tires, and they lasted the longest. The 858's and 270's I got the same mileage (almost ) as the mefo's, but the poor preformance is what ruined it for me. Got to have a good preforming tire!
I have distanzas on now, suposedly they had 5000 on them before I got them, we will see. Of course they are terrible in the slick stuff, but oh well, they rail in the street. Fortunatly I have an extra set of rims for the knobbs.
