Hello together! Just a stupid question: One of my freshly mounted tyres loses air. However, the pressure loss seems to be only up to 1.2 bar. It won’t be less. Does that have to be on the valve in this case or can the tyre itself be defective? I would have thought that if the tyre was broken, the pressure would have to drop even further. Is that right or can it also be that the pressure is kept at 1.2 bar for weeks? It is an A4 convertible with BBS CH009 in 8,5×19 with 235/35 R19 Dunlop RT, rubber valve, front left. Thank you!
