With 20" rims you need a 345/25 R20 in the rear that at ~26.8" diameter is closer to stock and your 305/30 R20 in front is okay at 27.2"

This is assuming you typoed and your rims are 20x12 out back and 20x10 in front as in your signature.

If you really meant 15" wide rims on back and 12" up front, IMO the 345 tire would look stretched on the 15" rear rim since the tire is only 13.6" section width.

I use this link to see what they would look like but the rim size only goes up to 13" wide:

Custom rims, wheel tire packages for your ride - RIMSnTIRES.com

The optimal with the 15" rear rims would be a 365/25 which is 14.4" section width and matches your front diameter at 27.2". When I looked a while back 345/25 are the widest 20" low profile tires I could find; not sure if that has changed???
