Tire pressures usually hovered anywhere between 1.8 bar and 2.2 bar cold at the stage start. Depending on which surface and which tires you had. I was starting stages in Catalunya with 1.8bar cold and if I remember correctly at the stage end it was not unusual to see the pressures at 2.5bar. That was with mousse. Today they might do a little different.
We put the same pressures front and rear.
On rough gravel rally I was a bit afraid to start stages with 1.8bar. So I started with 2.0 for a bit more safety in the first few kms. It's easy to knock a tire off the rim when it's got low pressure. it happened a few times to me, usually on the rear and usually when you hit banks or things like that. So either you watch out for them in the beginning or you don't care. It's a risk worth thinking about.
i had always been thinking that maybe it would have been a good idea to use a specific gas instead of air in the tires.
