Welcome to today’s riddle question with (hopefully) practical benefits Let’s imagine that we are somewhere with friends on a Sunday, a few kilometers from the home port, and when we leave the place, we find that some tires have decided to get rid of the annoying overpressure. Anyone who wants (or has to) to get home on the highway in this situation, and not only “to the next workshop” (which has to…), and also no desire for an ADAC-O rgie (just as a non-member) is, of course, happy about his useful tool and (instead of a spare wheel and flick-resistant Tirefit) full-fledged spare wheel… but, that is in most cases as old as the car, and in my case this already has half the H-mark behind it. And even if a tire in the UV-protected sheet metal pit ages less than an mounted one, it is no longer to be expected with the original wheel guide and the driving behaviour can change in the direction of adventure depending on the weather. And a summer tire is also what doesn’t make things better. Then you get angry, if you didn’t take care of it earlier, to take care of an alternative here. The first-aid kit steril part is also exchanged regularly, even if TÜV & co have always overlooked it and you never want to need it. The options are (in the rough, who knows more can say): – old summer tires from Leave 1998 on the unused steel rim and hope that it will not rain or snow in an emergency. – old winter tires after testing (the best of the 4) can be pulled onto the steel rim and hope that thanks to directional binding in an emergency it will catch one on the right side – new retreaded all-year or winter tires with non-track-bound profile can be mounted and hope that it is better than one of the previous variants Or in short: curing vs. directional ung vs. Cheapheimer. What would you like to drive around now if there is no serious alternative in the situation? (and please don’t make any probability calculations, that’s not the point of the question)
