Michelin is an excellent tire . I've got over 60 K on mine and there is still plenty left. A friend of mine with a Sprinter got a bit over 100K on his before he got new ones. Granted, he was pushing his luck....
The average should be about eighty six thousand K's depending on how they are treated etc, Mine are Bridgestone factory fitted C Rated eight PLY
Not so great on a gravel road, tends to slip about on the little marbles, that keep MY ESP busy.

Canada uses Michlin too, they are just so great and worth every
Great grip on roads, not bad on country gravels too, but not snow, but already performed very best for ALL Season Tire, we replaced it with same Michlins too
