I got a flat tire on interstate 80 out in the middle of nowhere in Wyoming. Pressure dropped from 42 to 10 in about 2 minutes. Luckily the leak was easy to find. I fixed it in about 20 minutes with a $20 tire repair kit and a $35 inflator from Amazon. I’m really glad I bought them when I bought the car. I’m on my way across the country for the second time. I’m glad I didn’t have to spend three hours or something waiting for AAA.
