Can Slime tire sealant be used to treat punctures in run flat tires?

We do not recommend installing Slime tire sealant into run flat tires. Run flat tires are not designed for tire sealant as the run flat tire structure was specifically created to indicate a flat and still be safe to drive on for a short period of time. Additionally, some run flat tires have a foam insert to help support the run flat concept. If the tire does have the foam insert, sealant will be absorbed in the foam and will not reach the puncture hole.
