You're saying all 4 new tires will be 275/40 r20 correct? The 4.8i with upgraded 20s / sport pack has the 315 width in the back. It would only make sense that the 275 widths you've bought won't fit on the 315 width rear rims that come with the car. Unless I'm seriously misunderstanding something with tire sizes.

sample: P225/50R16 91S
The 225 indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the tire's section width. Because many people think of measurements in inches, the 225mm can be converted to inches by dividing the section width in millimeters by 25.4 (the number of millimeters per inch).

225mm / 25.4 = 8.86"
But 315mm / 25.4 = 12.40" ... larger than your 11" specified.


Or are you saying that you've bought new rims as well?
