Tyres > Help > Tyres Help > What is tyre sealant?
Tyre sealant is a liquid solution that is used to repair punctures and leaks in a tyre. It is typically injected into the tyre through the valve stem and works by sealing any punctures or leaks from the inside.
Do tyre sealants work?
Yes, to some extent tyre sealants are effective at repairing minor punctures and leaks in a tyre. They work by coating the inside of the tyre with a layer of sealant, which fills any holes and prevents air from escaping.
How far can you drive on tyre sealant?
Most tyre sealants are designed to be a temporary fix for a puncture or leak, and are not intended to be a long-term solution. As such, it is recommended that you only drive on a tyre that has been sealed with a tyre sealant for a short distance.
Can a tyre be repaired after using tyre sealant?
Yes, a tyre can be repaired after it has been sealed with tyre sealant. However, it is important to note that the tyre must be properly inspected and repaired by a professional before it is safe to use again.
What is tyre foam?
Tyre foam is a type of tyre sealant that is designed to provide a more permanent solution to punctures and leaks in a tyre. Unlike traditional liquid sealants, tyre foam is a dense foam that fills the inside of the tyre and hardens.
Can a foam filled tyre be repaired?
Yes, a foam filled tyre can be repaired. However, it is important to note that the repair process may be more complicated than with a traditional tyre, and it is recommended that you have the tyre inspected and repaired by a professional.
Is it better to repair or replace a tyre?
Whether it is better to repair or replace a tyre depends on the severity of the damage and the age of the tyre.
It is important to have the tyre inspected by a professional to determine the best course of action.
Is out of date tyre sealant an MOT failure?
This is not listed as a direct cause. However, if there is anything which could compromise the safety of a tyre, this will likely be noted and possibly cited.
