Spent the rest of the the night swapping over the tyres to put the AT's back on and going over and checking the tyres, howeverbut couldn't find any cuts or snicks that would lead to all 4 tyres going down.

The only thing I can think of is that when letting some more pressure out of the tyres 1/2 way up a track that the valve didn't go back in or properly and it has been slowly releasing since.

Has this ever happened to anyone before?

Any suggestions on how to fix, is it as simple as getting the deflator and screwing the vauvle back in properly?
It's possible that if you have been in muddy ruts mud has got between the rim and the tyre. This happened to me on a few occasions on an older set of tyres. Since I changed the tyres I haven’t had a problem. I had to have the tyre re-set on the wheel on a few occasions. Depending on how much mud gets in depends on how quick it goes down. It can take between several days to a number of hours before I noticed it.
