Kumho 712's speed ratings?

[Todd Phenneger]

Some tire companies do this.   But the V-rated Kumho's
supposedly are a little softer sidewalls than the Z-rated but I
cant confirm this.  Sometimes its a tread difference as well. 
Usually companies do this associated with a Tire Aspect ratio
change though.   Wierd,
  I always get the higher but sometimes maybe it doesnt matter.
They are both sure to be great tires, happy cornering.
