Slow leaks from tires
I've an old truck that isn't used much, perhaps two miles once a week. And I have slow leaks from the tires. Not much surprise there, or so I'm told.
But when one was leaking more than the others I took it to the tire place and they said it had two nails. How can one guess if a slow leak is a puncture or something else?
What is the best way to maintain tire pressure?
