Continental ContiSportContact 2 SSR run-flat tires, 17"

Complete set of Continental ContiSportContact 2 SSR run-flat tires. Take-offs from my 2012 E91. Fronts are 225/45R17s, rears are 255/40R17s, which are the standard sizes for the E90/E91 AWD M-Sport package. The tires have less than 3K miles on them and still look virtually new; minimal wear. As an aside, the first ~1200 miles were accumulated on the Autobahn when I did EU delivery in May 2012, so you might say they have international experience... :-) A new set retails for 960 + shipping at TireRack.com. I'm asking 450, or feel free to make a reasonable offer. Pics of the actual tires, including date codes, are here: http://www.pbase.com/rselby/tires. Questions, send email to zhp@railtrainllc.com.
