Stans NoTubes Tire Sealant 16oz

Sealing tubeless tires. quickly seals smaller tire holes.

It just works on my road tires. Seals up most punctures, some you don't even realize occurred. I prefer to add it to tires via an injection kit through the presto valves w/ core removed and tire already mounted.

Stans Sealant just works. I have used it on road, gravel, and mountain bikes, all tubeless. On road with tubes I would get two or three punctures on a single ride. After switching to tubeless and using Stans, I rode over 1700 miles without a flat. The only issue I ever had was recently with one set of Maxxis Velocita tires where (quite a few) goat head thorns would puncture but break off and stay in the tire, leaking slower than what is needed to activate the sealant. Stans even worked for a ghetto tubeless conversion on an older (non-tubeless wheels and tires) mountain bike.

Works great! Fill the tire once and it's good for, well almost forever, or at lest the lifetime of the tire.

I regularly ride areas with a basketful of hazards, thorny cholla balls being most prevalent, and all I do when I get home is break off the spikes at tire level and leave them in the tire.

I just replaced a tire I wore the tread off and it still had the original fill of Stans doing it's job. When I took the tire off, the inside looked like a forest of spikes, made up of all the spikes picked up in the lifetime of the tire.

Way to go Stans!

I had waited too long to add sealant to my tires but had everything purchased when I picked up a nail on a ride. I noticed the nail when I got home but waited to remove the nail until I was ready to add sealant. Since the old sealant was dried up, the tire immediately went flat when the nail was pulled. Once sealant was added and the tire was pumped up, the sealant filled the hole within a minute. The hole was almost large enough to require a plug, but the sealant stopped the leak!

I've been using Stan's for a long time, I won't change what works!

I recently replaced my tubeless tire for the first time and so its the first time I have ever used tire sealant in this application. That being said, I have already tested it and it works great. I broke the sidewall of the tire while hopping up a sharp lip. I was devistated at first but when the 316 gap started to seal up I was super impressed. I thought such a large slice would surely be unrepairable but this sealant closed it right up and I have been riding on that tire ever since. Long story long, I highly recommend this product because it works

I had a terrible time setting up my tubeless tires with this sealant. I almost bought a new set of tires, but then gave another brand a try and that fixed the issue.

Best thing I did to completely stop goat head flats.

Been using this for a few years on my gravel bike. I've had punctures, but this stuff sealed them up nicely. no flats in a LONG time (knock on wood). I took the tires off the bike and noticed the sidewalls stick together making that a pain in the booty to re-install the tires. so it's not super friendly after months/years of usage.

Tubeless road is amazing. Stan's makes it that way.

Stans NoTubes Sealant! It just works as it is prescribed. Follow their direction and get the protection!

Stans NoTubes is a kickass company. Quality products just like this sealant. It's a classic.

Seals small holes and is easy to add after removal of the valve core. I've had practically no spillage.

I initially had good thoughts about this product, but I once got a nail in my mountain bike tire while riding. Out of curiosity I pulled it out and eventually the sealant sealed the hole along with some dirt sticking to it and I continued to ride on that tire for 3-4 more rides. This year, however, when I changed over to 30 mm Stans Flow MK3 rims and kept the old tires, I was unable to get all of the sealant off my tires (but most of it) and I figured the new sealant would seal it anyhow. Not so. In fact I have found that a new tire on a new rim with tape seals does better than an old tire with sealant. With the sealant I can get through a ride and lose about 10 psi of pressure and have sealant all over my tires by the end.

This was my first attempt at setting up tubeless tires, and I didn't have any issues. The sealant was easy to use and so far I have not had any issues with the tires.

I use it for my tubeless tires and it works just fine. I have used it in the past with good success. I will use it again.

First time using tubeless on cross bike, holds pressue great. After installation no lose of pressure, went a week before i had to top off.

This sealant is the best on the market. I use road tubeless and have had Stan's still work 8 months after originally filling. Great product.

Installation was pretty easy. Works good so far.
