They look remarkably like the ones on tirerack.com
370Z Bridgestone RE50A
I just put them to sleep for the night so I can't take any actuals right now, but these are as close to new as a used tire gets. Taken off in March and stored in my climate controlled garage wrapped in plastic tire bags for the Summer.
I'll try and take some pics tomorrow night after auto-x. The tires I'm selling were never auto-x'd or raced.
