Flat tires are not just a car problem that will keep you on the side of the road. Also, under-inflated tires caused by a cut can lead to a serious accident. Low air pressure in a cut tire will add too much stress to the tire structure and could cause the tire to explode while driving. If you have a cut in the tire, fix it as soon as possible. A little effort today will avoid a big problem in the future.

Step 1: rim cracked on the outside

Raise your car with a jack so that the cut tire is lifted off the ground. Place the jack closer to the cut tire than any other tire.

Step 2: a cracked tire can be repaired

Remove the cut tire with the lug wrench.
