I'm selling 2 brand new, never installed, Continental ContiExtremeContact tires (235/40/18) for $425.
At tiretrends.com. these 2 tires will cost $532.52 (shipping included). I bought them for my 18" rims but decided to go with 19"s. My 18"s (18x8.5 ET35) will be up for sale soon too, if anyone is interested.
