Falken or Kumho?

My wife is buying me the the 17x8" SLP ZR-1 style wheels in hyper black for my b-day. I'm looking at either the Kumho Ecsta Supra 712's or the Falken Ziex ZE 512's in 255/45 ZR-17 size. The price difference is only $32 so thats not an issue. Note on treadwear: Falkens 360 AA, Kumhos 280 AA. Any opinions are welcome.
Thx, Dale

Deffnitley go with the Falkens. The Kuhmo is just a cheap tire. The 712's have been discontinued anyway. The Kuhmo SPT's have replaced them.

Anyway, Kuhmo tires are known for thier terrible treadwear and overall "cheapness".

For a small increase in price, the Falkens are worth it.

Thanks, thats the sort of input I was looking for. Also, after further research I've discovered that the Falken tires are slightly
wider than the Kumhos and weigh less to boot, 27.4 lbs to 30.1lbs respectively. Less unsprung weight is always good.
