Watch your tire pressures
Cold tire pressure and warm tire pressure can change pretty dramatically when you run low profile tires. Today my 40 series separated from the alloy wheel, went flat, and I had to get it re-bead locked to keep it from leaking.
It's very common for alloy wheels to release their bead in cold weather so make sure your tire pressures are correct this winter because if you have a weak bead and pop it while driving hard in a corner it can be dangerous. Even if it is sitting still you can wake up to a flat tire and be late to work or school. (I woke up to a flat today).
So for safety and to keep from being late to where you need to be, watch those tire pressures and be weary of the bead on alloy wheels in cold weather.

i lightly bumped my aftermarket rims on curb, it looks perfectly fine no bent rim but every 3 days now my tire will get flat. its hard to tell when it low and flat cuz there stretched low profiles so they run like runflats and can barley even notice driving with a flat. my question is how do you lock the bead? i myself removed the tire and reseated the bead w compressed air, but are you talking about a type of glue sealant type RTV?

It's actually pretty simple; just use the correct sized tire for the rim 
One of the other causes can be oxidation of the alloy in the rims. Some rims can slowly "corrode" away from underneath the tire bead causing continual leaking.
btw, I know you were joking, but light as it may be, helium would rapidly leak out of most any tire. It's the ideal gas for leak detection because it slips out of anything not designed for tiny molecules.

Luxor has a great point. If you are going to run a problem tire, a good spare is extra important. I used my spare probably 5+ times over the summer due to tire leaks. "FAIL"ken 452's will bubble or leak and pretty much suck! Now I'm stuck with six of them that are a complete waste of money. Make sure the load weight can handle our curb weight too. Running a 215 tire on a 9"-10" wheel in the front with our curb weight can possibly be an issue.
