According to tirerack.com, you can install 20" wheel/tire size with different widths, but your rear tire size is off... it should be 295/40-20
But remember that the disadvantage of having different widths is that you wouldn't be able to rotate the tires.
The DSC/ABS system works on the basis of comparing wheel speeds. That's how it knows if one wheel is slipping or if you are about to go into a tailspin.
If you use front and back tires of different rotational diameter (so they rotate at different rpms for the same road speed), the system may give you a warning light and disables itself thinking it's a sensor malfunction. It may also have detrimental effects on your transfer case.
I would recommend that you make the front and rear widths the same.
PS - you really didn't need to post this question 4 times.
