If i was going to replace my tires right now, i would buy the Generals at the tire rack that you are referring to. You can get the General for the front in the stock size, plus they are available for the rear in size 245/35/19 for $127 each. The difference in diameter is only 1% according to the tire size calculator at: 1010tires.
