Tire degradation is not linear. Once it's at this stage it really, really starts to go. The less rubber there is the more difficult it becomes for the carcass to dissipate heat which will ultimately destroy the tire.
No trees were harmed to display the above message ..... however a large number of electrons were terribly inconvenienced
PR3's? Another Duffy, why not? I've seen worse.
Full Yoshi SS, Galfer wave rotors, Goodridge steel lines, Hel oil lines, Corbin GFL, Penske rear, RaceTech front, Hids, Givi hard bags with full lighting kit, Dyna Coils, K&N, Samco rad hoses, 9500ix/iQ, Pazzo, some bling, some CF.
Your center groves are pretty much gone but the tire will still ride fine AS LONG AS you don't ride in the rain. They wont disperse water well and the risk of hydroplaning will be lot higher.
My advice would be to change them asap or ride only in good weather and take it very easy and you probably could get another thousand km out of them that way.

It lookes brand new, to me...
Change it. Why even question it. We have enough odds against us out there and this is something you can control.
The upside is pretty small considering the downside.
Its 1.5/32 at the centre and 3 at the edges. New PR3 comes in about 7/32 at the centre and 5/32 at the edges.
On any given ride (HellsGate-Duffey, LML-Osoyoos-Winthrop-home, even Baker), the upright to lean ratio is about 80% upright and 20% (that's generous) leaning. Without adjusting the ratio due to softer compound at the edges, I think it is exactly within Michellin's usage prediction.
If the wear bars are all the way out, change it.
Tires = cheap insurance. It's the only thing connecting you to the road, so why chance it?
