I've filled 4 tires in a row on a 2006 Ford Taurus with no problems. The digital pressure gauge made this super easy, just set the desired pressure and let it run. Even though it was about 100F outside, the pump never overheats or needs cooling between the tires. The lowest tire was 8psi and easily inflated to 32psi. Despite what others said, the tube was enough to reach 2/3 the tire height. The only problem I had was the handle on the pump coming off, but it was easy to put back on.
