how good are Nitto "Extreme ZR" NT555 tires?

 

They are very good. Little to no road noise and they hook up well.

I can hook 2nd now compared to my falken's 255/50. Granted i have a bigger tire, 275/40, it performs well.

 

what's the treadwear on these?

I've been looking for a good street tire for my stock rims for now.. (FD) I have some enkeis for the track so I jsut need something that can hold up to a quick run up the mountains and still wear well and be good in the rain.
