From summer to winter and vice versa - Twice a year the tyres are usually changed. You could go to the garage for that. However, this is of course not for nothing. Do it Yourself is the cheaper alternative in this case, especially if you think long-term. The trip to the workshop costs about 50 Euro each time (100 Euro per year). If you do it yourself, you only have to make a one-time investment of 40 euros. You need a shunting jack and a torque wrench or a wheel spider. Knowing how to change a tyre yourself is helpful, especially in the event of a puncture. How exactly you should proceed you will learn here step by step.
