Slime Tube Sealant (Schrader / Presta)
North Texas is goathead and mesquite-thorn country, and tube sealant is the cheapest defense. Slime is a fibrous liquid you squirt into the tube through a removable-core valve; when a thorn punctures the tube, the escaping air carries the sealant to the hole and it plugs small punctures as you ride. It is not a cure for large cuts or pinch flats, it adds some weight to the wheel, and it can make future patching messier. For e-bike owners who hate fixing flats on a heavy bike, a few ounces per tube is a sensible trade. Check that your valves have removable cores first.
Best for: Thorn-prone areas · Riders who want fewer roadside repairs · Commuters on heavy e-bikes
