Got a deflation issue

[BigonaBianchi]

I got in from my loop, no problems..left the bike in the hall...five minutes later the rear tyre deflates. I take the tube out inflate it, an hour later it is still inflated. I cant see any damage to the valve and it was a new tube in last week. The only difference is that today I had it inflated at 110psi instead of my usual 100psi. I checked the inside of the tyre and found no evil things penetrating through.

Any clues??

Practical joker?

Nah..there's only me and the lodger here...............hmmmmmmm

Though the valve looks ok, I'd still think it was the most likely culprit. But I don't have a lodger as a possible suspect.

check the valve. I had one with the slightest of tears which took me a while to find

A slow puncture that leaks a bit more when the tyre/tube is hot from use?

BOAB, I had that the other week, put more pressure in the tube cycled to his house and got a pture when I was leaving, Ifixed it and pumped up with a trackpump and it happened another twice on the third timeI grabbed a spare wheel, he still has mine so I can't say for sure but I suspect it was a nick on the insideof the rim, a loose spoke or damaged rim tape or as I've had previousl something sharp and minute in the tyre which only shows when the tyre is under mor pressure.
