Hi! So far I have changed the tires myself on our two cars and I will continue to do so. Storage is too cumbersome and time-consuming for me. While I am waiting in the workshop, I am already finished myself… However, I wanted to make the whole thing a little easier and get away from the cross-key.Variant 1 Put up compressor in the basement, lead air line in the basement to the outside wall of the house, in order to comfortably connect an air hose at the parking place Advantage: Compressor can also be used for other activities (although I haven’t used it so far), impact wrench has sufficient power.Disadvantage: Expensive matter, elaborate installation of the air duct.Variant 2 Heavy battery impact wrench, e.g. from Makita the DTW1002Z with 18V. Advantage: I have a lot of device from Makita, all compatible, inexpensive.Disadvantage: Sauhemes Gerät. I do have a large Makita battery impact wrench (BTW450), which is however too weak. What do you think?
