you just have to love kevlar beads, dont you? folding a tyre up like that looks wrong.
but that, seriously, is a michelin pilot for a PUSHBIKE? interesting... very interesting
tried em out on a moto once. expensive, gripped well but i felt a bit off on the cornering? they were meant to be the best!
also, i noticed a slight tendency to wear on one side. after i sorta noticed it, a week later...the other side was bald!
not the centre mind you...and was on the front. didnt favor it any more, just happened.
but, they do have a reputation for making high mileage tyres, so yeah...see how it goes
a lot depends on rollers and tread type. knobby tread disintergrates rapidly. slicks last for ever. too large a roller, slipping, will shred anything.
good teeth on a roller will only shred if they slip...once again, wrong sizing. but theyre great when sized properly
a five year old tyre lasts twice as long as a newly purchased tyre ive found.
