YK420 is a "store brand" built specifically for Discount by Yoko.
Not a 320 treadwear as Dennis stated but a 420 rather.
Discount carries the Falkens as well, and aside from the fact that mine were FREE, their prices on the Falken Ziex-512 are competitive. If you decide to do these, consider the 255/50/16 as they are identical to stock diameter and have a 99W rating, and look spectacular.
Also, never pay the first quote at Discount - They have some "haggling" room.
