Looking through Tirerack it seems Yakaoma S.Drives are being discontinued. Can anyone confirm? That'd be a real shame, as Yokahoma produced them in a zillion different sizes and they were one of two realistic options on Tirerack for 215/40/17 x 235/40/17 staggered sets that are common in our cars. We're getting to the point where we may have to shop lesser known brands like Nankang and Federal, or try a 235/45/17 tire on the rear. I shudder to think of the effects of the latter on my speedo readings.
