[demo 9]

I run tubeless on 823s eyeball an amount of stans, i have always used the DH 2.5s in super tack and the UST in supertack. Recently i got some maxxis 3C 2.5s (4 of them) I mounted them up tubeless the same as i always do, pump up. let bubble, sit, ect...

I go out in the morning to find a small pool of black stuff under all the tires, i figure wow odd, whatever, clean it up and walk away. Next morning same deal, i go and look and the tires appear to be fine inflating wise. (still feel firm)

I raced on them over the weekend and they are fine, not paying attention i forget to check to see if they are bleeding. While working on my bike in the basement (absolutely covered in dust) i notice the whole bead on both sides is wet with this oily substance, as if the whole tire burped at the same time, still solid as a rock, but still bleeding...

Stans + 3C compound = no dice?

I've been using 823/3C's for about 2 years now and have noted the weird black "wetness" on the bead at random times.... that said they have been totally fine for me and haven't lost pressure.

I've heard sanding off the "grip ribs" on the bead also helps with sealing, just something for you to ponder, haven't tried it myself.

Wont cause any issues when i used to run maxxis tires i had slow reezays and 3cs do it from time to time no issues ever, just a little pool of yuck.

anybody know why, im sure that ill wreck the tire before it dissolves, but its getting quite old having to clean up after my bike every morning, its not a pet!

I assume its the top layers oil base rinsing off from the sealnt acting as a detergent in some fashion. You could try dish soap and clean the tire before mounting them up in the future... aside of that get you maxxis cats a litter box or rub there tread in it and swat them... "bad maxxis"

 

[S.K.C.]

Hmmm... Sounds more like the tires are "sweating" instead of bleeding. A fresh set of tires esp. Maxxis are incredibly soft and "hot off the press" so to speak. If one were to leave a brand new tire in a room for several years, the tire will actually dry out and the sidewalls will crack, a condition known as "dry rot". This is due to the evaporation of the oils and other chemical used in the production of the tire left behind after the vulcanization process.

IIRC Stan's is an ammonia-based latex sooo... sounds like the Stan's is interacting with the fresh rubber, causing it to "sweat"... most likely oils from within the tread layer where the majority of the rubber is.

If I'm not mistaken, Maxxis is aware that Stans is used in their tires and have made their non-UST tires compatible with Stans for quite some time.

Still - I'd keep an eye on the tires, especially around the bead area and the sidewalls just to make sure it's not something more serious.

EDIT: DAMN you Bullcrew! LoL.

Yours was a better explanation anywas! LOL

fwiw, I'm getting the same thing on my year old UST High Roller on my trail bike. Doesn't affect pressure. that being said, that tire is a replacement for the previous one that developed a "tumor" when the rubber delaminated from the casing. Exact same tire: UST High roller trail. I figured it was a fluke, but this second incident of weeping is making me weary...

I had this issue a while back on 823/3c, plus the tire was losing some pressure. After some more riding and adding more Stan's all problems disappeared. Rock solid setup for me.

Forgot about that theres issues with Maxxis blistering up/herniating in the sidewalls as well as the logo goes muddy colored... Had logos discolor and weeping but buddy had the blistering on his. I never had it happen but Ive seen a bulge or 2 on them.. (his tires not mine)

Edited: Thats not true I had a minion blister out when I lived in Lewiston so it was 4 years ago or so...
Its been a while Ive used a minion for a short stint in the last 2 years (on a bike I bought) and havent been on minions solid for 4 years...

I've had a 3c tubeless on one of my bikes for years (multiple tires). I've never seen that happen. I use diluted molding latex though.

That could be a big part as well, I called Stans about the amonia a few times and a good example is Kenda tires the Kenda logo goes poo brown after a couple of weeks. It definently leaches through and especially bad on Kendas.

Stans claims the amonia content is real low (next too nothing) in his stuff but somethings breaking down the rubber a bit or atleast stripping the oil properties out. Caffe latex doesnt do it but doesnt work half as good...

Kwoo Hows the home brew working out??? Been wanting to mix some up its just too easy to buy stans but Im definently curious???

Works way better than stans just because you can get it thicker. I've put too many holes in tires and watched that watery stans just squirt out and never seal. It does dry out in your tire to a little more of a mess but it also creates a latex glove-like coating along the inside. I'm definitely a fan.

Even the stuff I've got has an amonia smell to it though. There must be something else going on with stans specifically.

PORN-TEX!!!

I've been waiting for 'woo to jump in on one of these conversations!

Woo - don't you use a mix of Stans and the Porntex?

EDIT: Thanks for the link Woo!

The tap stuff is cheaper and is essentially the same thing (minus the colors and funky perfumes). I just used the porn stuff before acadian got some of the tap stuff for me. I live near reno so you know.....when in rome.....gotta get what's available.

I am running a Minion DHF 2.7 3c up front and a Minion DHR 2.7 60a on the rear ghetto tubeless w/ stans on 2010 Deetraks. I notice after a day of riding the sidewalls are dry. After the bike sits overnight, I have small wet spots along the bead of the tire. The tires hold pressure great, so I don't worry about it. I haven't had a pool of liquid on the ground as you describe.

 

[quickneonrt]

not to thread jack but a question for Bullcrew and Kwidoo. I have 823's but the guu i bought them off of drilled out the presta valve to use schrader valves. Do you guys think it is possible to use Stan's strips with them to make them tubless?
