The oxygen content of the air is very important...it provides the ability of the tyre to compress when hitting obstacles.
For this reason, I divert the exhaust gas of the RD350 for a full hour into the son's "greenhouse" in the early hours of the morning.
Later in the afternoon, I put the compressor in there and after sucking all the old air out of the tyres with the missus' Dyson, I pump them up with oxygen enriched air.
You wouldn't believe the difference that it makes
