So I'm trying to figure out WHY audi would put a directional tire on the spare rim? Maybe I'm missing something, but would it be considered safe to use a directional tire in the opposite direction for which it was intended?

I wouldn't want to throw a directional tire that's on backwards hard around a corner.. you'd probably lose all your traction on that wheel. Plus, it may make for generally uneven and quirky driving.

But I guess my point is, that if audi is going to go to the trouble of giving me a full rim spare, they could at least make it a functional full time tire that could actually be used to replace all four instead of just two of the current wheels. *shrug* call me crazy I guess..

firstly, the idea is that you ideally want all four corners carrying the exact same tyre. audi typically chooses performance tyres that are "directional." this "directionality" with regards to how a performance tread grips, is minimal. the main reason these tyres are labeled with a rotating direction, is that after many miles of use, the belts and guts of the tyre take a "set", due to acceleration and braking forces. to change the rotating direction after they've taken a "set", would oppose the current "set", and could cause de-lamination, and possibly catastrophic failure. but to use an unused tyre against it's rotating direction would be totally safe and grip-wise, virtually unnoticeable. i am not a tyre expert, i can't even spell it correctly. tyre experts, correct me if i'm wrong.
