Ive done about 20,000kms on my MTZs and they wouldnt be 1/3 worn yet. Definitely depends on how you drive. I should see 60,000kms out of mine. IN saying that, i was going for KM2s but the tyre shop jacked the price up at last minute, the MTZs were $30 cheaper per tire. KM2s can be found for $300...
