Does F1 rules strictly say that F1 tires must be filled with air?
Can they fill them with helium? or something else that is lighter than air. Or mabybe something that is heavier -who knows might as well do good for overall cog and weight distribution if tires are a bit heavier and chassis a bit lighter.

The norm in motorsport is to use nitrogen because its more stabile in relation to temperature i think.

Ferrari and maybe others used a HFC gas mixed with nitrogen couple years back. Idea was to get better heat transfer or something... But I don't think it matters too much which gas(ses) you choose as long as it's dry. And dry nitrogen is cheap and abundant.
FIA would ban anything that is too flammable or toxic on safety grounds.
Teams decided to ban using helium for wheel guns to reduce costs and maybe for the green image as well. Weight advantage from using helium in tires would be negligible even for F1.
