Slime Self Sealing Tube

This tube is designed for tires with a diameter of 24 inches and a width between 1.75 and 2.125 inches. Please check the sidewall of your current tire to ensure these numbers match before purchasing.

The Slime sealant inside is formulated to remain effective for up to two years. After that period, the sealant may lose its ability to seal punctures effectively, even if the tube itself is still holding air.

No, this specific tube is equipped with a Schrader valve, which is the wider, car-style valve. It will not fit a rim drilled for a Presta valve unless you use a rim adapter, though we generally recommend matching the valve type to your rim.

The tube comes pre-filled with a liquid sealant containing fibers and particles. When a puncture occurs, the escaping air forces the sealant into the hole, where it clots and creates a flexible, long-lasting plug.

Yes, because the tube is pre-filled with liquid sealant, it will be noticeably heavier than a standard, empty rubber tube. While this adds a small amount of rotational weight, most riders find the trade-off for flat protection to be well worth it.
