Default What are the symptoms of a bent wheel?...

I think I might have a small bend in one of my wheels, but I have visually inspected them and can't see anything... When driving 25 to 45 I get a thunk...thunk...thunk... that seems to increase with speed. Its barely noticeable, I think I feel it in the steering wheel. Any tips on diagnosing this and finding the bad wheel? Or could it be the tires? I have pirelli pzero rosso's with about 10K on and 2 track events on them, they are close to the wear bars. When I put the snows on I don't hear/feel the noise.

Default Vibration in the steering wheel (at higher speeds) is the first give away.

Default Generally:

If the noise and vibration is coming from the tires itself, at higher speeds the vibration goes through an oscillating wave of increasing and decreasing power. If it is constant I would think it genenrally means the rim itself. Lucky for you, identifying a rim problem is as easy as two things, grabbing a friend or taking the thing to a rim/tire shop.

Tell a friend to drive aside the car looking at each tire individually travelling at 60 mph or whenever the vibration is most apparrent. Choose a smooth road, clear of traffic. The messed up rim/tire should be very easy to spot amogst the others.

The other thing u can sdo is just take it to a shop to get it balanced. Their machine ill tell them if the balance is off or untrue. A visual inspection of the tire /rim will check for bubbles, dings, dents, or cracks.

I'd be surprized to see ANY kind of Audi modded or not! I take it you're in OKC?
