Self-Sealing Smart Tubes with SLiME Tire Sealant Inside
All SLiME Smart Tubes are factory-filled with a precise volume of SLiME Tube Sealant. Smart Tubes seek out and seal punctures as they happen, preventing flats, sealing instantly, repeatedly and continuously. Put trust in your tires and ride without worries.
The SLiME Smart Tube will instantly seal most punctures in the tread up to 1/8" (3mm). SLiME is Not Guaranteed to seal sidewall punctures, pinch flats, glass cuts or punctures over 1/8" (3mm). Be sure to remove any foreign puncturing objects from tire. If necessary, re-inflate tire and rotate wheel to create seal. Prior to inflating or deflating a SLiME Smart Tube, rotate tire so valve is at the 10 or 2 o'clock position. This helps sealant to flow away from the valve preventing it from clogging the valve or air source.
The guy at my LBS tried to talk me out of these once, saying that they weigh so much more than a normal tube. But I will gladly trade a few grams of weight to not have to stop and patch a pinched tube out on the side of a trail. Seems like a no brainer really.
I have seen a lot of bad reviews for slime tubes but I have loved mine. Seals from most small punctures before loosing more than a couple psi. Even on large holes still seals but occasionally needs some air added. Once it seals it seems to be back to new condition even after literally 30+ thorns was a reliable inner tube. One thing people don't realize is the slime only works if you use the bike. It needs the rotation to force the slime towards the outer edge of the tire, if its not rotating the slime will just go to the bottom of the wheel
