Michelin Energy XM2 145/80 R12 Suzuki Alto 1.0L 15,000 miles July 27, 2016
Still the thread pattern is in good shape .
Very soft compound which means it is best suited for hatchbacks.
This tyre is not meant for sportive drive.
Dry grip is good enough for handling at moderate speeds.
Wet grip is ok.
Confort level is very high as the tyre is soft and there is no noise.
Fuel efficiency increased by 20%.
Previous tyre was MRF and compared to that, this is way better.

Would recommend XM2 for small cars....
