Yokohama don't usually have this kind of sale very often, unlike Bridgestone, so get them while you can.
Only tyre that sticks out, would be the Advan AD08Rs, for track use.
Makes a 1600 set of tyres, only 1200.
Eligible Product List:
ADVAN Fleva V701

Pretty sure your local tyre or car shop can do the same deal, as I've asked a shop that wasn't listed on the Yokohama website and they said they could do it.
