Can Slime tyre sealant be used to treat punctures in run flat tyres?
We do not recommend installing Slime tyre sealant into run flat tyres. Run flat tyres are not designed for tyre sealant as the run flat tyre 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 tyres have a foam insert to help support the run flat concept. If the tyre does have the foam insert, sealant will be absorbed in the foam and will not reach the puncture hole.
