Mainly I use it to inflate bicycle tires or wheelbarrow.
Had she but even for inflating car tires mounted on my car used (Golf 6). This seemed a bit flat after the change from winter to summer tires after the weight of the vehicle rested on it. Pro tires I had increased the air pressure of approximately 2.5bar 2.1Bar on what was done per wheel surprisingly fast and without much exertion or sweating.
