Plug It Yourself:
Slime brand products makes a tire repair kit that lets you plug tire holes just like you pay big money for at a professional mechanic shop. This comes in handy when you pick up a nail or screw on the highway and you don’t want to waste time changing to the spare, or being limited to the 50 mph and 100 miles range limitation of the small donut spare tires that most cars are equipped with today. There are several times that I have pulled out a nail, plugged the hole, and inflated my car’s tire in much less time that it would take to change to the spare. These plugs saved my behind when I popped two ATV tires while out in a remote area.
