Tire sealant

[MikeD]

I'm becoming disillusioned with Orange Seal Endurance, as this is the second time it's made a puddle of sealant on my garage floor after I pulled out the offending thorn. Plus, it's expensive. This is on a 700x38 gravel tire at 50 psi with about 3 oz. of sealant in the tire.

This article did a test on sealant http://www.mtbiking.com.au/gear/tubeless-tyre-sealants and Stan's came out pretty good, although a lot of folks don't like it.

Although this article is 6 years old and things might have changed, I like that they put the results in a table.

Any recommendations?

Trucker Co or Stans Race.

I've had mesquite thorns do the same - take the thorn out thinking it will seal up quickly but it just shoots out like a water gun. Maybe it's because the bore of the hole is so perfect? I just learned to be ready with a small sized plug.

Maybe you should try regular Orange Seal? It's sealing capabilites are higher than Endurance. Endurance is marketed as a long lasting sealant. Personally, I'd rather have flat sealing as the top priority as I don't mind topping up every 4-5-6 weeks.

I'm actually using Stan's on my gravel bike. I started off with TruckerCo and it didn't work well. I admit that I didn't follow their directions. I think I looked up on the internet how much sealant to use and used Stan's chart which indicated 60ml. After a year of not having fun with TruckerCo, I noticed that the side of the jug recommended 120ml. Doh! TruckerCo is cheap but if you have to use twice as much, it's not that cheap in the end. I did start doubling my dosage and it was better. TruckerCo's sealant is now their 2.0 version so maybe it's better.

I switched to Stans after I ran out of TruckerCo and Stans performed way better. My tires sealed better, lost less air over time, and running over a million goat heads was not a problem. The only plug I've needed so far was for that big mesquite thorn previously mentioned.

Stans Race has been great on both my gravel bike (panaracer 32mm) and my road bike (pirelli tlr race 28mm).

I might switch back to regular OS, which I used before. I understand it dries up in the tire pretty quick, which makes me hesitant to use it again. Maybe I'll blend the original with the endurance.

OSS... My current monitor for the product. I got a batch that I thought dried out so easily and failed to seal reliably even on small punctures. Happens I guess.. I've just moved on... No reply from the manufacturer about that batch batch number... This almost 2 years ago.

Point posted correctly per hole configuration in size. Some of the large ones and shape would be impossible for any sealant.

Dry sealant anyone? Think about it.. the air pressure distributing a variable size particle...

I should have added.. with all the engineers around this site I think a dry sealant is possible (?).

[USAisDOA]

Trying to generate a little interest in the idea of dry sealant...

My idea is some kind of a particle that gets a little bit gooey/tacky under pressure.. hence doing a better job of staying in the potential punctures (?). Thereby helping the larger variable size particles seal.

In my experience Orange Seal is far superior to all other sealants and the only one capable of sealing the tyre at 90psi. All the others can barely hold 50psi.
I had one rear tyre that lasted 5000km and had been punctured 10 to 12 times without issue.
I have found that sometimes the puncture can be so small that only air can get out. I carry a small pin nail with me which enlarges the hole enough to allow the sealant to do its thing.
