Slow puncture advice
I've had my winter wheels on for a few months now and one tyre has a persistent slow puncture. It loses 10psi a week. Is it worth having the tyre refitted with a new valve or am I better having a different tyre fitted? I've previously ran the wheels as dailys without issue so I'm confident they aren't damaged .

I've done about 50k on these wheels before they were relegated to winters and have been laid up since last March. So I'm kinda ruling out wheel damage although I guess they could have deteriorated. I have another spare set of Nokian WR D4s so I may as well fit one of those, seeing as it will be the same labour. Just pumped it up now - it's lost 6 psi since Saturday. It could have a nail in it but not that I could see.
Role on April when I can put the summers back on!

As above Find the leak!
Leak detector spray or fairy liquid (or anything that foams) in a trigger gun spray all over including rims then wait for the bubbles.
Bets on,as mentioned its the rim leaking on the bead. Corroding aluminium and bubbling paint allows air to escape between the rim and tyre. Even on alloys that look mint, they can be heavily corroded on the bead.
Tyre replacement is only needed if puncture is too close to the edge or the sidewall is damaged...that includes internal damage which can happen if driven underinflated.

Leaking valve was obvious once I had the wheel removed. Tyre place replaced it free of charge (can't be bothered to ring it through the till....). Couldn't see anywhere else where bubbles were forming or air escaping but having checked the pressure a day after the new valve, it's still going down but at a slower rate....
Not much longer now until I can refit my summer wheels then I'll think about getting the winters refurbed or replaced.
