Are the weeps from the rubber side down? I've noticed sitting wheel end up with Stans separating and the clear liquid from the result likes to seep. If the rubber is still supple, I'd think it's fine. That's why I spin sitting wheels from time to time if they are tubeless.
Tears of neglect for sure!
@rick81721 those look like nobby nic tread pattern, i had the same thing with the old set that were on my fuel before i replaced them. It didnt hurt anything and i lived with it for 9-12 months before i tore a couple of the tread blocks off and replaced them. as long as the tires are still holding air i wouldnt worry.
All my Maxxis tires weep, especially when they sit for awhile. Just ride.
