I just put the Toyo's on about 1000 miles ago, so I have no feed back on life of the tread.

All I know is that they ride great and if I get 50,000 out of them for the price I'll be very very happy.

The last 30,000 on the OEM Dunlap's was pain and misery, got 50K out of them but a lot of vibration and cupping which was probably my fault for not rotating them often enough.
Cupped out at about 20K.

Good Luck
