Minion EXO TR Stans seepage

I noticed today that my Minion DHF EXO 3C TR rear tire has small spots of stans all over the sidewall. I wiped it down and sure enough the spots reappear confirming that the sealant is coming through the sidewall. I can't find any spots on the tread area and nothing appears to be coming from the bead. The tire has just under 300 km on it! It doesn't seem to have lost pressure. Is this normal for these tires? Anything I need (can) to do to stop it? Front is fine, so I suspect is has something to do with all the flexing the rear goes through on the hardtail has caused micro holes in the sidewall.

Exact same thing with mine. Doesn't appear to affect the performance though

strange my tr ex 3c's have not done this..

That usually goes away after the first ride. Weird.

I've seen a few tires do it. I don't think it matters. It did it on my front tire when new but stopped eventually never noticed any issues.

Although my picky buddy bought a new tire to swap out, paranoid of losing air haha.

I never had any leakage when it was set up new. I refreshed the sealant at the end of Decemeber, but I'll probably add another 50 ml prior to the next ride and see what happens. All the seepage is approximately equidistant from the rim, so I suspect it is indeed from running low pressure which compresses the tire at this point. It's just hard for my OCD tendencies to see this lol

Sidewalls also get abraded over time which leads to more seepage…

Last night I installed some fresh tires on my wtb i23 frequency rims. I put dhr2 tr exo 3c rear and dhf 2.3 tr exo 3c front. Zero seepage through the side walls. I rolled them around horizontally for a few minutes on both side before installling on my bike.
On a side not they look skinnier than the ones i took off. They must stretch a fair bit after inflating??
Is that a thing?

yup

yup

i thought i was imagining it, thanks. On the up side the maxxis TR tires are so easy to mount tubeless on the wtb frequency rims it took my 15 mins to do front and rear.

I've got some DHF EXO blah blahs on my bike. Front is fine. Rear always seeps from the sidewalls and it's done it since new. Adding more Stan's doesn't make a difference. I blamed the dog at first because it looked like he'd been peeing on my bike wheel.

It holds air, rides fine, looks janky, in that order.

This is what it looks like right now. Some new very tiny spots. Pressure feels the same.
