    Which is different from tubeless bicycle tire sealant. It performs a different job.

    I bought GP5000 before I knew about sealant or air compressors/tubeless pumps. They seated on my wheels with no problem using the pump in the usual manner. Negligible air loss overnight.

    It's always a good idea to bring a tube even though I usually don't. In about 12 years of riding tubeless road tires I've had two cuts in the tire (sidewall) that didn't seal or at least didn't hold enough air to get home, so I had to install a tube.

    IMHO, not carrying a tube is one of those things like not keeping an eye on the gas gauge in your car. The resultant situation is TOTALLY PREVENTABLE.

    Spare tubes when running tubeless road tires?

    I pulled a thorn out of my gravel tire in the garage. Sealant squirted out. Wouldn't seal. Tire pressure was about 50 psi. Garage temperature was about 45-50 degrees F. Using Orange Seal Endurance. Put some fresh sealant in and it sealed. Why wouldn't it seal? Temperature too low? There was plenty of sealant in the tire, as there was a sizable puddle of it on the floor.

    I've had good luck turning the wheel so the puncture is on the bottom while sloshing it around a little, others do the same while tapping the wheel on ground also.
    Either way, why tempt fate by not carrying a tube?

    Any of my wheels tires changes are done easily by hand. I can usually get them off without levers.

    Nope. But I've seen many others that come off fine.

    Yeah, did that. Still didn't seal. The sealant must not work as well at lower temperatures, although I would think 50 degrees isn't that low. I always carry a tube. Also, I recommended never pulling out a thorn when out in the road, in case the sealant doesn't work.

    I've been using Orange Seal Endurance for years. I use it year round down into the 20°'s. Never had a hole not seal (never had it spray either).

    I agree, I wouldn't pull a thorn.

    The fact that it worked when you put new sealant in suggests that the existing sealant had separated, and so the thin liquid was what was coming out of the tire. If anything, sealant should work better in cold weather because it will get thicker with dropping temperature. Had the bike been sitting for a while, such that the tire wasn't spinning and therefore the sealant wasn't being sloshed and mixed?

    Yeah it was sitting. Just before a ride. Also, I'm not shaking the bottle enough before putting sealant in the tire. Thus, it's thinner than it should be.

    Yikes

    Sealant is a mixture of rubber particles suspended in liquid. If all your putting in your tire is the liquid it ain't gonna work.

    I gave the bottle a few shakes. The problem is if you shake the bottle too much, OS foams up and then how do you know how much you've poured out in a cup to inject or pour in the tire? I guess I'm going to have to figure out how much it weighs per fl. oz. and weigh it beforehand.

    Rubber particles? You sure? I know there's some glitter in there.
