HI, I have in my possesion 4 brand new Continental xtreme contact all season tires size 235-4-Zr18, That were intended for my 04 Audi S4 Avant but due to circumstances beyond my control were only able to be on the car for 1.4 miles making them the most brand new used tires on the market, these tires are awesome in the snow and jus as good in the dry weather conditions AWESOME ALL SEASON TIRES!!! MY SECOND SET that i had purchased i liked them so much and you will too! i have them set at a price of $450.00 which is negotiable but the orginal tires were at an msrp of $175.00 each so you see what a deal this already is!!! please mail me at [email protected] and i will send you any info you need as well as my cell number, paypal greatly preferred but not only option highest bidder will get the tires!!!
