If the nail in your tire is starting to leak, its likely that it will have trigged a tire light. A flat tire generally triggers the tire light after about a variance of 4-7 PSI. If you find that the tire light has not come on yet, it’s possible the nail has not actually gone all the way through the tire.
If you do not have a flat tire warning light, you can always use an air pressure gauge to check your tire for signs of a slow leak. If one of the tires seems significantly lower than the other three, it’s possible that the nail punctured the tire. If either one of these quick tests indicate a flat tire might be in your future, call the professionals at Nashville Mobile Mechanic Pros or your local tire shop to help you get your tire back to working condition.
