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.
Step 3: repair cut tire
Use a sponge to apply soap and water to your tire if you can’t find the bar right away. A small bar may be difficult to see, but it will cause the soapy water to bubble from the air escaping from the bar. Rub the soapy water all over the tire in case there are multiple cuts.
Step 4: cracked tires
Use a tire polish to polish the cut area. This will prepare the area for the vulcanized fluid and the tire patch.
Step 5: a cracked tire can be fixed
Apply the vulcanized liquid to the small slit and let it dry.
Step 6: repair cracked tire
Fill the tire with air according to the air pressure specifications on the side of the tire.
Place the tire patch on the vulcanized liquid. Make sure the patch is completely flat and let it sit for at least 5 minutes. Then put the tire back on your car.
Tip: how to repair a cracked tire
- Have a mechanic check your patch. A professional mechanic will be the best judge of how well you were able to repair the bar.
- Some bars are too big to repair. Take your car to a tire store and buy a new tire if the bar is too big for the patch.
- Do not try to fix cuts in the sidewall of the tire. These cannot be safely repaired and you will have to replace your tire.
