Most tyre companies use dry air.
As piast9 has pointed out (as I did above) the adsorbed moisture in the tyre will dominate over the moisture content of the air unless you've got a really horrible source of inflation gas!

As piast9 suggested, it's the whole process. This is why climate controlled storage is used extensively. Although not always in F1. Michelin had some impressive climate controlled trucks and they're now used for WEC.hardingfv32 wrote:Is moisture absorbed by the tire before or after mounting?

The only racing tires manufactured in Argentina are not "radials", but cross ply and its shape vary A LOT, not only from tire to tire, but also when you change pressure.DaveW wrote:That is an assumption made by all. But why should it be the case? A tyre is not completely rigid and I guess its shape (hence enclosed volume) is likely to vary a little with a temperature.Tim.Wright wrote:Consider that the air inside the tyre is a fixed volume of non moving air....
