Purchased a pair of Falken ZE-912 just under 2 years and 16,000 kms ago (50/50 city\town) for our Subaru Legacy and already they are borderline ready to replace.
The car does run higher than stock power (230KW vs 191KW at engine) but it is AWD and tiptronic so isnt exactly doing burnouts, plus 90% of the time its mainly driven by girlfriend who drives nice.
Falken website say these tyres are rated for about 60,000 kms of use (that's with rotations). I could live with 3 years\25,000 kms but 2 years\16,000 kms seems a little on the low side.
FYI Falken's 5 year\60,0000km warrenty is not valid outside USA\Canada. So I gather I don't have a leg to stand on.
