I just picked up my s4, and need a desperate tire change. DiscountTire.com says that the Fittipaldi Argus tires 18X8.5 will fit the car. Has anyone done this before? What's the max width I could take the tire to w/o touching? I'd like 245, but can the car handle that with a drop? I'd like to lower the car to about the back rim height of a stock m3. Does anyone have any suggestions as to what brand might work best to lower the car?
