Well, I am beginning to think that is pretty close to cost. A while back a place here in town told me they would get me a set for 10% over cost; it seems like it was in the $210~220 range. I just thought that they could be had for a cheaper price, and could not afford them at the time. If nothing is better I might end up back there; you just have to pay tax that way, and here it is 7.5%
Also, I remember JDM placing a for sale in the classifieds for some they were "dumping", and it was $189 a tire. If you take that and go 10% over you have what I was quoted. Kindof seems like about $190 is cost. They might get a better price if they buy 50 from Nitto....
