~Its going to take about $500.00 to join the Rotate Club~
Fronts are only 4 1/2" wide rims (no good for the rotate club)... Keep one of them old ones for a spare, and sell the other one...
Note: Continentals all-season tires are rated 4 1/2 stars out of 5 (they are good) TireRack tells no lies...
Read this Link, and you will get the Drift of what you can do...
