Only time will tell.

The Michelin site says, "Nearly twice the mileage of competing cruiser tires." So, if they're talking about a ME880 that lasts 8-10k miles, it meas they could last 3x of the softer tires that get 5-6k miles. So, it's plausible. We'll have to wait and see.

In the meantime, they ride great and IF they last as long as Michelin says they will, I cut my tires budget in 1/2 to boot.
