I am getting a set of rims 18x8 (front) and 18x9 (rear) soon and was wondering if this set up would work. 245 45 (front) and 275 40 (rear). Does anyone have this set up or have a picture of how this would fit?

 

This would kill the stagger. You want 245/40 and 275/40.

can you please explain what the "stagger" is.

 

rears should be taller than fronts, in your setup they would be near the same(without doing the math, the fronts might be taller)

its just how most RWD cars do their setup; and its how the TCS/VDC expects to have them oriented.

otherwise width was the real question there, and your fine there; but go with 40 profile front and back.
