How to Fix a Cracked RIM That Leaks Air?

How to Fix a Cracked RIM That Leaks Air?

Rims are made of metal, steel, alloy, and aluminum and are surrounded by tires. The sudden cracks in these parts cause air leakage in the wheels, and you can feel the wobbly and unstable driving conditions.

How to Fix a Cracked RIM That Leaks Air? You can fix the cracked RIM that leaks air with TIG and MIG welding techniques. In addition, you can also use metal adhesives or cold-welding techniques like J-B weld and blue magic quick steel. You can also try bead sealants and replace the whole rims if the cracks are larger. The repairing methods depend on the type, location, and extent of cracks. 

It is not suitable to drive with cracked rims because instability can increase the risk of accidents and the rolling issue of your vehicle over the road. In addition, it compromises the safety of the drivers and passengers because of poor car handling and shaking of the steering column.

Can you repair a cracked RIM that leaks air? 

The repairing of the cracked rims depends on the type of crack. Some of these scratches come in a parallel direction, while others appear perpendicular.

You cannot fix the parallel ones because they can scratch again due to their direction and weight. However, repairing is possible if these are smaller in size and visible in thin lines.

You cannot fill the large holes or marks with welding and adhesives because of their markable size. In addition, it can disturb the structure of the whole part when you want to resolve the problem.

Furthermore, the repair option also depends on their location. For example, you cannot rejoin the scratches if these are present on the side of the lug nut, stem wall, and backside.

How do you fix a cracked RIM that leaks air?

It is unsafe to drive with cracked rims that cause air leakage from the tires. You can use different methods to resolve this issue.


You can try two welding techniques, including the TIG and MIG methods, depending on the type of material.

TIG is suitable primarily for steel or metal type material because of their strength, while you can use the MIG type for aluminum and alloy rims.

In the TIG type, tungsten inert gas is used to join the two parts, while MIG uses metal inert gas with continuous heat to melt the two parts and fuse them.

You have to clean the affected surface and remove dust and dirt before applying the welding procedure.

Sand the scratched area with an electric sander to level the surface and make it smooth. Take a drill machine and make two holes on both sides at the ending point of the cracks.

The drilling of holes is necessary to prevent further damage during the welding procedure. Now use the arch and fill the affected area with filler.

The heat and the filler fill this space and then wait for the drying procedure. Then, use a high-grit sander again and level the surface to protect the wheels.

Use JB weld adhesive 

These are the metal adhesive material with epoxy resins to bind the cracked and broken metal end. These have high tensile strength and can easily secure broken or scratched ends perfectly.

It is the cold-welding technique, and you have to use the two mixtures that are present in the kit.

Park your car on the ground and leveled surface, jack up the affected wheels, and remove the tires. Next, take a wire brush to remove the dust and dirt from the rims and locate the crack marks.

Use the alcohol swaps to wipe off the surface and make it clear and clean. Then, take out the material from the hardened resin tubes.

Mix both of them well with a stirrer until you achieve the desired color. Apply the mixture to the scratched area and use the flat scrapper to level them and remove the excess.

It is necessary to wait a few minutes until the epoxy mixture dries. Do not add tires to the wet mixture because it can create messy and worse results.

Replacement of rim

Replacing the entire rim of the cars is the better option for fixing the cracks in them. It is unsafe to drive with broken parts because of poor handling and stability of the steering column.

It increases the risk of accidents because of sudden blow out of tires. In addition, you have to change them entirely if the marks are large and you cannot repair them with welding or metal adhesives.

Match the size if you change one side for better driving conditions and maintain stability during driving.

It is suitable to select the ones that match the quality and materials of the previous ones.

Try sealers

Bead sealers are present in the market to adhere the broken metal parts perfectly. You can use these sealers to fill the cracks in the rims

It is essential to identify the location and direction of the scratches before using sealants for their binding.

These are best to fill the marks near the stem area. The sealant is not a suitable option if these are on the back side and present on the lug nut area.

Separate the rim and tires and cleanse them well to remove dust, grime, and road salts. Then, apply the bead sealers using a paintbrush and attach the tire again.

Blue magic Quick steel

Metal glue is used to adhere the two metal parts together. It has high strength and is a long-lasting solution for cracks.

It is easy to use and more durable than welding because it is resistant to temperature fluctuations.

Clean the rims and remove the dust and grease from their surface. Next, apply the release oil, so the mixture does not adhere to the surface where it is not needed.

Take the adhesive from the tube and mix it well with a stirrer. Mix the dough until you feel the heat and soft texture from it.

The warmness and softness come when two chemicals are homogeneously mixed. Apply the adhesive on the marked area and then leave it for 50 to 60 minutes until it becomes dry.

After leveling the surface with a sander, add the tire to it, and go for a test drive.

What causes cracks in the rim?

The cracks in the rims come due to the use of low-quality or cheaper wheels that cannot resist the damage of the road and put pressure on the steel or metal part.

In addition, the issue also comes due to the overloading of your vehicle. Therefore, it is suitable to check the weight-holding capacity of your car’s tires and rims while adding weight.

The issue also comes when you drive with punctured or flat tires. Many people do not know when the air pressure in their vehicles’ tires becomes low.

Moreover, driving or parking on poor roads or curbside and hitting with potholes cause this issue because of improper balance and stress.

Accidental hitting with other objects and automobiles causes this problem and compromises your safety during driving.

You can fix the issue by monitoring the health of the wheels and checking the air pressure in them continuously.

Drive and park carefully on the curbside so it cannot put pressure on the rims.
