Your local Uniroyal dealer will run through some mandatory checks such as looking at the area of the tyre that’s affected, the tread depth, the cause of the puncture etc. before deciding if they can repair a tyre. Did you know, for example, that if you get a puncture in the shoulder or side wall of the tyre, it is illegal for them to repair it?
They will also remove your tyre from the wheel to check for internal damage, something you wouldn’t be able to do by yourself.
