    I came back riding in the woods and found these little guys stuck on my tires. I pulled one out and in 10 seconds the air is gone. I pulled out like 20 of them and there are many more broken ones I could pull out by hand. All of them leaving hole on the tires.

    I am wondering if anyone knows what they are and if I can seal the holes with any type of sealants?

    Any help would be appreciated thanks!

    PS. Sorry I think I attached the pictures twice but I don't know how to remove them.

    They look like your typical thorn... for me personally if it was just one I would try to fix, but with that many I would just spend the money on a new tire.

    Those little goatheads are the second reason Stan's and tubeless are one of the most significant mtb inventions. Flats used to be part of almost every ride. I don't miss those days...

    Ah, the hated tribulus terrestris. http://upload.wikimedia.org/wikipedi...terrestris.jpg

    Had one show up in the back yard last year. Unfortunately, I didn't know what the plant looked like at the time, and it got to the seeding stage, which can happen rather quickly. Still pulling up sprouts this year.

    Dirty $anchez,

    So you think Stan's would seal all the holes? I have got like 50 of them on both tires.

    Knoob,

    Yea, I thought tubeless was already more puncture resistant so I didn't use the sealant. Wasn't sure how it works Does it plug the holes automatically whenever something puncture through the tire?

    I've had glass, goatheads, and a piece of wire floating and sloshing around in the Stan's in my tires before.

    It will seal most small punctures; you'll most likely never know they were there.

    And yes...it works automatically.

    One thing i have learned with tubeless, especially when you are low on stans or you suspect it is all dried up.....put the thorns back in, or find a thorn and shove it in the hole. It will get you back home/to the car. Once home, you can put more stans in and take the thorns out (although if finde it works better to leave it in most of the time).

    Stans works ok, but there are better sealants. My personal favorite right now is Slime Pro.

    Those damn things are everywhere... East Coast too. I got a bunch the 1st day out on new Racing Ralph snake skins a couple years ago. Stan's sealed up the holes no problem and they are still rolling trouble free. I did harvest a massive boog outta the front tire after a year or so (yeah, I heard it for a while and ignored it). Nothing even noteworthy has grown back since I picked that one

    Thanks for the info guys! I am gonna try the Stan's and see how it works.

    I have just recently started riding on trails and I was devastated to see so many holes on my tires. But it's great to learn the fix.

    yep, goatheads are the worst. Try growing up in Nevada. We had on the order of hundreds of plants when we moved into our house there. First bike ride, flatted out both tires less than 20 feet from the driveway

    Over time it collected in my full susser's front tire. After a while I didn't hear it bloppin around in there. Then, I noticed when bombing down hills my front tire was goin whop whop whop (outta balance style) so I finally decided it was harvest time

    It might be a little hard NOW to seal it, although you'll still be able to do it. I'd suggest adding an extra ounce or two to help with sealing it, use a compressor because it's not going to set as easily with the holes, and be prepared to rotate the wheel to move the sealant to the right spots. It'll be fine though.
