Practical impression
Breakdown sprays are only known to many by hearsay; assessments from workshops, retailers and the Internet sometimes differ significantly. Irrespective of the formal test objective, it is assessed whether such a spray — as a temporary solution, not as a permanent repair — will enable a safe journey to the nearest workshop.
Application: The illustrated instructions make it easy to use. Continuously pressing the trigger until it is completely emptied requires some force.
Driving impression: After driving off, a slight imbalance is noticeable, which is significantly offset by the recommended distribution route. After around 10 km, the measured tire pressure in the test was above the output pressure of the intact wheels.
Conclusion from a consumer perspective: For small tread holes, the spray offers a quick, easy emergency solution. Observe operating limits (not for cuts, sidewall/valve damage), comply with the speed limit and plan a trip to the workshop. A can in the trunk can help decisively in an emergency.
Note: Tester's subjective user experience — including previous experiences, expectations, and personal impressions during use. It reflects a personal, situational assessment and is not part of the DTI assessment. It does not replace objective examination or advice and does not establish any legal claims. The aim is to give consumers an assessment that is close to everyday life.
