Yesterday the BMW started the tyre pressure warning. The Cross Climate (for 3 weeks on) on the front left has too little air. So quickly to the petrol station (3 km) away and once looked. The tire had only 1.2 bar. So to the usual 2.6 pumped up and back home. This morning the same game: car on, after 400 m the tire warning. Again to the tank, again only 1.2 bar in the tire. I hear a clear hissing when I squat on the tire. Due to the darkness I could every What else can’t it be, if it has been running smoothly for three weeks, right? Since I am dependent on the car and I don’t get to work without it: a.) How far can I drive with the car max.. I have to drive 3 km to the next tank, can then pump it up, then has to get another 7 to the station. On the way back it is 600m to the next tank. b.) Why is the tire not completely empty, but always retains 1.2 bar in it? c .) Can you tend to fix something like this? If not, then I would order a new one now. Need the days for further distances.
