With a drop I doubt the 10's will clear up front. Most folks run a 7" or 8" with 245/60 to maybe 255/60. Depending on the drop method, the wheels may interfere with Tie rods ends or require trimming of lower a-arm. Normally a 15x7 with 3.5" backspacing seems to do OK. I do not think in a 15" you will be able to clear more than a 4" backspacing up front regardless. Rears on the 10" seem to do OK with 4.5" backspace with out clearance issues.
