Kumho Tires for Gen 1

[V10SpeedLuvr]

I've been told that Kumho XS in Gen 1 sizes are on national backorder with no ETA. I really don't want to pay the $400 more for a set of PS2's. Anyone have a Gen 1 set of Kumho's in stock? Or even a different name brand? The fronts are available in many name brands, its the rear sizes that noone can find.
