ive never heard if it...what are the advantages? if any? :?

Supposedly....
Tires last longer because Nitrogen doesn't oxidize the rubber inside the tires.
Nitrogen doesn't expand or contract as much during the heat cycle, so air pressure stays the same.
Nitrogen doesn't outgas(seep through the rubber) as fast, so you don't have to air up as often.

I don't think i'd trust it off craigslist seeing as it wouldn't be worth the money it cost to prove that the tires really had nitrogen in them.

At several local tire shops, nitrogen is under $20/tire. You don't need the craiglist'* nitrogen tires to sway your buying decisions.

Its just a gimmic. That only applies if oxygen NEVER enters the tire. That means that the first time you have a leak and fill the tire, you lose any bennefit of the nitrogen.

Yup. Although small cylinders of nitrogen aren't expensive, and they're even selling them at parts store specifically for that purpose.

Not that I'm a proponent. My tires are air filled.

dont worry, if i was actually thinking/able of buying it, the nitrogen would have nothing to do with my buying decision

i was just wondering because ive never heard of it, i guess it makes sense in a way, but im gunna stick with my free air

There'* more, but that'* the first one I remembered. There'* pretty good debate in that thread.

thanks for that i mustve completely missed it but it explained it well

The two main advantages of Nitrogen are:

The tires won't lose pressure because nitrogen molecules are larger than oxygen molecules and so they will not leak out of the tire rim or valve stem.

Nitrogen does not hold water in it like air so you won't get condensation inside the tire which could cause an imbalance or corrosion.
