Does Slime stay liquid in the tire?
Slime is a liquid. A bright green, thick liquid. There is no air inside your Slime bottle, just the powerful puncture preventing liquid. The liquid doesn't expand (like a foam) when it enters your tire.Does tire Slime damage tires?
Tire sealant may damage — rather than fix — your tires.Sealant is designed to disperse and fill up puncture holes while aided by the heat of the tire. If it doesn't warm up fast enough, it can pool toward the bottom of the tire and lead to potential wheel misalignment.
