i dont know man.
i just comparing with ecopia ep200 vs 912 vs gt radial bax2. sime tyres never used it.
btw what model sime tyre? since i bought second hand gen2.

did u buy new 912 or used 912? with standard gen2 spec 195/55/15? and new tires? like what i done to my gen2. i change the tire on July 2010 and the 912 manufacturer date on 1010. mean about mac 2010. new tire made in thailand. and i only used the tire for about 1 and half year so far really serve me well. connering at genting and bkt beruntung never have problem with that.

but my review maybe inaccurate since now im comparing it with 205/55/16 tire which is used on my preve. probably the preve kerb weight and high ground clearance distributing to less grip feeling when taking corner too.

it is the best asking the same car owner with the same spec to share review. btw how fast u taking corner? plus u said ze 912 sidewall too soft. so far from all tire i ever use. 912 is the hardest sidewall. maybe it is me who rarely use many tire. hehe  

i start using car from 2009.
the only tire i ever try are :

yokohama A drive (195/55/15 - for gen2)
Falken Ziex Ze 912 (195/55/15 -for gen2, 185/60/14 - for myvi extreme, 204/40/17 - for myvi extreme - after change rims to 17inch - CANNOT TAHAN THE NOISE than change back to original rims and NCT5 tires)
Goodyear NCT5 (175/65/14 -for myvi extreme)
GT Radial Champiro Bax2 (standard tyre comes with preve cfe)
Brigestone Ecopia EP200 (for preve cfe).

so i just comparing will all this brand and specs. most problably inaccurate since different specs and different car model will affect the results too ..right?
