Just got off the phone with Tirerack and found out that Kosi discontinued the K1 rim in 15x7 with 114.3mm x 5 spacing. Infact they have no wheels that will fit that don't weigh 18-20 lbs each or cost more than $300.
They have lots of 16" but we cant use them. They say no one buys 15" rims any more, and that 16" or 17" is what has the largest selection.

Does anyone have a source for reasonable ($150) wheels that will fit the 7?
