Punctured and subsequently repaired tyres of the two most commonly used types in Europe for motorcycles and scooters have survived comprehensive high speed tests carried out by TÜV (Technischer Überwachungsverein) in Germany, with good results. Four popular types of car tyre were also tested and were driven problem-free after nail punctures had been repaired by using the same method. The car tyres were in addition subjected to an extra long test while under load. Two of the Safety Seal repair methods were thus proved to pass this recent impartial testing.
