Fitted to my Proton Satria GTi these tyres are ok but in my opinion they should be classed as a mid-range tyre and not a premium.
Tread wear resembles that of a mid range tyre mine lasted roughly 15000 under normal driving conditions and wore evenly but I didn't find that they had great levels of grip in dry weather when pushed slightly. Wet weather performance was terrible! Kind of point and hope... also quite a noisy tyre.
I also had an issue with these directional tyres pulling the car very slightly left when going in a straight line however after having the tracking and 4 wheel alignment checked and re checked and eventually moving to asymmetrical pattern the car drove straight and true... very odd.
For me its a no brainer, either "Invest" that little bit more for something like a Goodyear etc etc to get the performance, safety and longer lasting tread or pay less for something like a Toyo or a Kumho that are far more grippy and last about the wear about the same tread wise.
