I drive my 2007 Toyota 4Runner to school everyday and today before I left home my friend pointed out a nail in my tire. I drove home with no problems but it's late at night now and too late to go to my local shop to buy a plug kit to repair it. Do you think it's safe to drive it to school and back tomorrow? It's my back-right tire and the on-board computer has not had the light go out signaling that the tire has lost air. Just need a quick professional opinion. I have 2 routes to take to school: one on the highway going through somewhat stop&go traffic and the other taking side streets which potholes. Appreciate any feedback. Thanks!
