9 Steps to Fix a Cracked Rim and Stop Air Leaks Easily

Fixing a cracked rim that leaks air can be a challenging task, especially for those who are new to it. However, with the right approach, you can easily repair the rim cracks at home. In this article, we will provide you with 9 easy steps to fix a cracked rim that leaks air.

How To Fix a Cracked Rim Without Welding

Step 1: Park the Car

When you notice that the tire pressure is off, the steering is shaking, or it’s tough to handle the vehicle, it’s time to park the car in a safe place where you can easily access the tire rims. Remember to turn off the engine and apply the parking brake to ensure that the vehicle remains stable.

Step 2: Locate the Crack

Once you have parked your car, carefully locate the crack on the rim. If the damage is on the surface, it should be easy to find. However, if it’s on the edge, you may need to put in some extra effort to locate it. Use a brush to clean the area around the crack to detect any micro-cracks around it.

Step 3: Inspect the Crack

After locating the crack, inspect it to determine the severity of the damage. Try to find the crack angle as this will help you fix it quickly. If you’re unable to detect any micro-cracks, you can drive your vehicle slowly.

Step 4: Clean the Crack

Clean the dirt, debris, and paint from the rim after locating the crack. Use a brush to clean the dirt and debris, and high-pressure water to remove the paint. Wipe the rim with a rag soaked in alcohol and let it dry.

Step 5: Prepare the Resin Mixture

While the alcohol is drying on the rim, prepare the epoxy resin and hardener mixture. Take out the hardener tube and then the resin tube, and stir the mixture until you observe a color change. Keep stirring until the mixture color changes completely.

Step 6: Apply the Mixture

Before applying the epoxy mixture to the rim cracks, use scrapers to slip under the mixture and put it on the crack. Apply force to attach the mixture properly to the damage and cover an extra 2 to 3 inches around the gap for better results.

Step 7: Allow the Surface to Dry

Do not drive the car immediately after applying the epoxy mixture to the rim cracks. Instead, leave it for 10 to 12 hours for drying, or apply the epoxy mixture and leave it overnight. Giving it enough time to dry will create a strong bond.

Step 8: Attach the Rim to the Wheel

Attach the rim to the wheel after the surface has dried properly. Follow the manual to connect the rim to your car’s wheel.

Step 9: Perform a Recheck

Perform a recheck after completing all the steps. If the rim still leaks air, it’s best to have it repaired at the nearest repair shop.

Knowing the Causes of a Cracked Rim: How to Fix the Problem

The causes of a cracked rim can vary based on the type of vehicle, but there are some common reasons that affect all cars. Below are some factors that contribute to a tire’s cracked rim.

Flat Tires:

Driving with a flat tire increases the likelihood of rim cracking. A punctured tire reduces performance and creates cracks in the tire rim. Keep in mind that sudden temperature changes can cause tire punctures, and a tire blowout due to outside temperature and tire pressure can also damage the rim.


Potholes are a major threat to alloy and aluminum rims, and repairing aluminum cracks can be expensive. Severe damage to the edge of the rim can occur from deep and sharp potholes, which may require additional car parts. Small cracks can also become large holes if left untreated over time.

Curb Damage:

Curb damage is another leading cause of a cracked rim, which can depend on driving habits. If the curb’s width and length do not fit with the rims, the tire rim is likely to become damaged. The same goes for reckless driving near a curb while parking or moving the car.

Defective Wheels:

Using poor-quality wheels is a common cause of tire rim cracking. If cheap wheels are installed to save money, it can lead to costly repairs and significant wheel damage. If left untreated, the cracks will become visible and sharp over time.

There could be other reasons for a cracked rim in addition to the ones mentioned in the previous passage. Some other possible factors that can cause rim damage include:

  • Overloading the vehicle: Putting too much weight on the vehicle can cause stress on the rims and lead to cracking.
  • Corrosion: Exposure to salt, water, and other chemicals on the road can cause corrosion on the rims, which weakens them and leads to cracking.
  • Manufacturing defects: In rare cases, the rim may have a manufacturing defect that causes it to crack even under normal usage.
  • Improper maintenance: Neglecting to maintain the wheels properly, such as not checking the tire pressure, can lead to a cracked rim.

It’s important to identify the underlying cause of the cracked rim to fix the problem effectively. If you’re not sure what’s causing the damage, it’s best to take your vehicle to a mechanic or wheel specialist for a professional diagnosis.

Identifying Signs of a Cracked Rim

When a rim is cracked, there are several indicators that can help determine the severity of the damage. Recognizing these symptoms can assist in understanding the type and angle of the crack, making it easier to find a solution. Familiarizing yourself with the essential signs of a broken rim is crucial.

Steering Wheel Shaking:

If the rim is damaged, your car’s steering wheel will shake continuously, and you may hear various noises while feeling vibrations from the steering column. This can make it challenging to control the vehicle, increasing the risk of serious accidents.

Imbalanced Tire Pressure:

Uneven tire pressure is another significant sign of a damaged rim. When the edge is cracked, you may notice that the tires are unbalanced. As a result, these tires will lose pressure while driving, ultimately affecting your vehicle’s fuel economy. If the crack is inside the rim, it is difficult to fix and can cause tire pressure loss.

Poor Handling:

Driving with a cracked rim can lead to poor vehicle control. The steering wheel will shake, and tire pressure will be unbalanced, leading to this situation. Turning while driving becomes difficult and almost impossible, especially when taking sharp turns.

There are a few other signs that can indicate a cracked rim:

  1. Visible Damage: Check the rim for visible cracks or damage. Look for any deformation or warping of the rim, which can indicate a crack.
  2. Air Leaks: A cracked rim can cause air leaks, which can cause the tire to lose air pressure quickly. If you notice that you need to inflate your tire more often than usual, it could be a sign of a cracked rim.
  3. Vibrations: A cracked rim can cause vibrations in the car, particularly at high speeds. If you feel your car shaking or vibrating, it could be due to a cracked rim.
  4. Wobbling: A cracked rim can cause the tire to wobble, particularly when driving at high speeds. If you notice that your car wobbles, it could be a sign of a cracked rim.

It’s important to address any signs of a cracked rim promptly, as it can be dangerous to continue driving with a damaged rim.

How to Fix a Cracked Rim: Expert Tips for a Perfect Repair

If you are a new driver and need to fix a cracked rim, following these expert tips can help you find an easy solution.

  1. DIY Repairs: You can attempt to fix cracks on the back and inside of the rim on your own, as these are less visible areas of the wheel. However, it’s important to remember not to weld cracks on the front of the rim, as it can alter the structure of the wheel.
  2. Seek Professional Help: If you notice cracks in the pin and lug area of the rim, it’s best to contact a mechanic for assistance. Attempting to fix these cracks on your own can be dangerous and cause further damage.
  3. Consider Replacing the Rim: If the cracks have a Y shape or parallel cracks, it’s best to replace the rim altogether. This type of damage can compromise the integrity of the wheel, making it unsafe to use.
  4. Leave Aluminum Rim Repairs to the Professionals: If you have an aluminum rim, it’s important to have a mechanic repair it, as welding aluminum can be difficult and requires specialized equipment. Attempting to fix an aluminum rim on your own can result in further damage to the wheel.

Remember that driving on a cracked rim can be dangerous and compromise the safety of your vehicle. If you notice any signs of a cracked rim, it’s important to address the issue promptly and seek professional assistance if needed.


Yes, a cracked aluminum rim can be repaired. Depending on the severity of the crack, it may require welding or simple patching. If the crack is extremely severe, then replacing the wheel might be necessary. However, this should always be done by an experienced professional who specializes in repairs for automobiles or bicycles with aluminum rims.

Is it worth repairing a cracked alloy wheel?
