Stan's Tire Sealant is the number one rated tire sealant on the market. Just two ounces of Stan's Tire Sealant in a converted standard tire or a tubeless tire can repair up to a 1/4" hole instantly. One quart will convert up to 8 tires.
Stan’s Tire Sealant will stay liquid in a mountain bike tire with a thin casing for two to seven months on average. Riding in arid climates or storing the bike in a hot area will require more frequent monitoring of sealant levels.
Thinking of going tubeless and that you can just buy a can of sealant and be good to go? Not so fast! Having tubeless compatible wheels and tires is critical. Check out our selection of tubeless tires and tubeless wheels.
Stans works really well in tubeless tires and in tubes with removable cores. In a hot dry summer, it a couple of ounces usually goes dry in a couple of months, but it's easy enough to just pop a small area on the bead and squirt more in.
Simple to use, does what it's supposed to. What more could you ask?
This tire sealant works well for small punctures, however gravity has to take it where it needs to be for it to work, so you might have to "slosh it around" and hold your tire in various positions.
Does what it should but seems pricey for what it is.
Went tubless about 4 months ago and have not had a flat since! Stans is the best sealant for preventing flats. In Arizona everything has thorns so I am amazed by Stans!
Stan's is the best tubeless tire sealant currently available. I have been using it for years and it just works. Of course it is critical to have a tire/rim combination that is compatible to conversion. Not all combinations will work no matter what sealant you use.
