I wonder why so many user here likes XM2. I previously had these tyres and its bad. Hard, noisy, expensive but long lasting.

There are many other tyres which are cheaper and can perform better than XM2.

The XM2 is really an old obsolete tyre which is in dire need of a replacement.

Don't because its Michelin and it is a good tyre.. For this case, it isn't.

Agree, very overrated tire.

If you value the life of the tyre more than the value of your own life...
Then yes, it is value for money 
For me I would stay far away from XM2 due to its bad braking performance especially in the wet.
So be warned.

Maybe you should try other eco tyres.
Had these almost from the start of driving my new myvi 10 years back.
On the 14 inch wheels, it only gave 10km per litre. Gave them up at 54k km because of the severe chipping on the tread face.
Went to 15 inch wheels and to Yokohama Blueearths and that gave 12km per litre! And that excludes the slight increment in tyre circumference also.
Both sets of tyres were run at 33 psi, no need to blow them up super hard and shrink the contact patch and ruin the ride.
So yeah, Michelin xm2, noisy and hard.

I would recommend  the Yokohama over the Xm2.
Before i sold the myvi 1.3 ezi, i had just put a new set of Hankook Kinergy on but did less than 10k km on it so can't really form an overall opinion on the Hankook. FC remained more or less the same.
Maybe even an wheel size upgrade or at least to a lighter set of 14 inch wheels because the stock wheels are very heavy.  All up to your budget,  really.
