slowly leaking tire

[r2, 3 dude]

for the past 6 weeks or so.. I have had to add air to my passenger side front tire every other weekend.

is my tire shot? I would think it would go flat faster. Can it be repaired or do I need a new one?

I am pretty sure all my rims have some slight bends. I am planning on restraightening/refinishing them. was planning on using Wheels America. Any other suggestions?

I will have to get the tires dismounted from the wheels so is there something i should do at the same time? should i replace valve stems, etc? I am trying to avoid buying new rims and/or tires.

I have an 330xi w/ 17" Continental all weather tires, i think they are the same that come stock w/ the car.

I had a leaking tire past month and I thought it was the rim too but it was not, the tire had a screw on it that only let very little air to go out.

I would take the tire in and let a tire store take a look at it. You could have a bad valve stem or something in the tire. They should be able to find it.
