I am posting my (4) slightly used Falken Azenis RT-215's for sale (size 225/45R17). These were mounted right before Nationals last year, so they have about 2000 miles on them. Tread depth is still pretty good. I'll get an accurate dimension tomorrow, but it's around .200". They have a mold date of 46/2004, so they are just over 2 years old.
I have no idea on their worth, but since they're not made anymore I'm not sure if people are still looking for them. I would venture to guess $400 OBO.
I have (2) more of the same tires, but their tread depths are only ~.100". Make me an offer on these guys.
Please e-mail me, as I do not check this forum often. firstname.lastname@example.org
EDIT #1: Tread depths are .196" for the (4) and .091" for the (2)
