I got a new car in 2019. It’s the most expensive car I’ve owned in my life but nothing compared to some of the other cars where I live. In the last four years I have had a flat tyre about six times, and each time I found a nail stuck in my tyre. At first I assumed it was bad luck but AIBU to think that someone is doing this deliberately? Prior to owning this car I had flats but don’t think they were ever caused by nails. And if it is deliberate, how do I find out who is doing it and stop them?! Any advice would be much appreciated.
