My father was an OTR bus driver. He kept a ball peen hammer in his grip that always went with him. He never got into a bus to drive it without using it to hit every tire. You can tell a 10 pound difference in tire pressure by the sound/rebound of the hammer. Precise? No. Good enough for his purposes? Yes. Would it have found your flat tire? Definitely.
This is exactly what I did as an OTR trucker for 20 years. Worked great for me. Good hearing is a professional drivers friend.....I still hear the turbo singing.
