Hello, my car was standing at the roadside for 3 weeks and today I noticed a plate on the back right. During the last ride everything was fine and since I ran past the car every now and then in the 3 weeks, I think that the tire was still full a few days ago – but I’m not sure. My question: If a tire is still full after 2 weeks of service and after another week flat, it makes sense to refill it and hope that it will be e hold air? Or should you replace it immediately in such a case? Is it possible that the valve has not kept tight at too low tyre pressure and is again OK at normal tyre pressure? LG
