Slow puncture: What would you do?

OK, so my rear tyre has a slow puncture, measured on sunday as losing 4psi from 38 to 34 over the course of a 4 hour ride, I tend to pump it up again every couple of days (yes I know thats quite a pressure difference, but most of the time I don't push it enough to notice much difference)
I've done 3-4k on my PR2s that are probably good for another 3-4 at least.
I'm reluctant to change them because of the life left in it but I'm also keen to try some nice PR3s.
Can I get a slow puncture repaired easy enough? or should I just bite the bullet and get some new ones on there?

a bit rambly and no clear question but opinions/thoughts please

Probably more likely to be leaking from the valve or round the rim I would have thought, so might not need to replace tyre to resolve. If it were me I would take it to a tyre place and see what they say. or stcik the wheel in a paddling pool or summat and see where the bubbles come from

Some places will repair, and others wont. Find one that will and then take it in. Tyres are not something you want going pop at the wrong moment. They will tell you if it's just a leaking bead / valve or tyre and probably charge you about £20-30 to sort it if they can. general rule is if it's damaged in the centre then you're OK, damage on the wall and it's a new hoop unfortunatly. could well be the valve though as bemji says.

Washing up liquid mixed about 30:1 with water, splash it around and look for the fizzy bit.

If there is no nail in it then it could be a bit of a leak on the bead or valve, either way feel free to pop over and we replace valve or pop it off bead and reseat it. Neither is big job.

I`ve got a puncture repair kit that uses the tacky string which can plug a bigger leak , I`m in Colwyn Bay if you are in the area I will show you how to fix it

do some burn outs, then get a new tyre.

Yeah, lets subject a known bad tyre to forces that its not rated for and see what happens shall we...

Well I can recommend the sticky string repairs, my tyre got a puncture at 1500 miles on the way to AR10, Rictus repaired it for me using dmc's kit.

Since then I've done 2500 miles on the same repair, never got it plugged properly and even done a on it.
The tyre needs replacing now at 4k but the puncture is still fine and has never lost pressure, perhaps I got lucky where the puncture was, in the groove of the tread?

If you can't find an obvious leak and re-seating/replacing the valve core does not work, try some ultra-seal. It's green gloop that gets pumped into your tyre and stays there for the life of the tyre. Opinions on the stuff are mixed but I've never had any trouble with it.

If you expect the tyre to last several years then you may have a problem with the ultraseal clagging up on the rims making it a bit of a job to clean off for your next tyre change but otherwise I've not heard many horror stories from the stuff and never noticed any riding issues with it right upto daft speeds.

How long has the tyre been on the bike? Do you know if the valve was replaced at the last tyre change?
