Reveal yourself son of Einstein!
I thought it would
attract hoots of derision! it's all just A-level physics this stuff, with wild assumptions thrown in left right and centre (especially the bit about pure water vapour), and using numbers to disprove someone's opinionated post is just cowardice.
Ive been pondering the nitrogen in tyres question for a while, and this post was just the excuse I needed to read a few old text books. The moisture question had me thinking too - as my tubes are old and knackered and full of water and if I could be bothered I could dry them out and just use dry air (scuba tank), and I always worry that they will pop when it is sunny... but I'm not going to bother now - just leave them damp and fill them from the Aldi workshop compressor with no filter on it like I've always done..
I'll still get free nitrogen fills from the local Costco when I get the tyres done as usual - as this has been proven experimentally, but I wouldn't pay for it or worry about topping up with air because I check my tyre pressures regularly and have an airline handy.
Urm, an introduction?
