First off...these are track tires. Using them on the street is a problem, I know this all to well. Down and dirty... 4 215/45-17 Toyo R888. 2 have darn close to full tread, 2 are are just about at wear bars. Asking $150 for the set of 4, cash, pickup in Columbus, OH. Will ship at buyers expense. Figure it will run about 75 bucks to ship these in the US. The details... These are 25th week of 07 build. Yep, they are somewhat old. They have been stored properly. You can still very easily press a thumbnail into the tread, they are still very soft. Currently they are wrapped in shrink wrap and stored on a pallet out of the way of things.
