I am getting rims sizes 20 x 9 fronts and 20 x 10.5 rears. Car will be lowered 1.4 front and 1.3 rear. The front tires will be 245/35/20. I want the rear tires to match up with the fronts so should I go with 265/35/20 or 275/30/20? If not what size do you recommend?

I went with 295/30 and 255/35. I have an AWD and they are perfect and within <1% diameter. I swear by them. Check mine out http://www.customwheeloffset.com/wheel-offset-gallery/2/wheel-offset-2009-cadillac-cts-flush-stock-custom-rims

Here is another one with the same front as you, lowered and he did 275/35 but i didn't run the diameters to verify if they are same size.
