9 Easy Steps To Fix A Cracked Rim That Leaks Air: A DIY Way

How to Fix A Cracked Rim That Leaks Air

Having a cracked rim on your car is an eyesore and can cause serious safety issues. A cracked rim can lead to air leaks, affecting your vehicle’s performance and stability on the road. The following 9 easy steps will guide you through fixing a cracked rim that leaks air.

Step 01: Park The Car

Please park your car on level ground with enough space to easily access all four wheels. Ensure the handbrake is engaged and the vehicle is in gear (or parked). It’s important to note that if you plan on lifting the car off the ground using jacks or ramps later in this process, ensure it is safe and secure.

Step 02: Find The Crack

After parking your car, the next step is to find the crack on the rim. If the damage is on the surface of the rim, it should be easy to spot. However, if it’s a smaller crack on the edge, you may have to search carefully. Take your time and examine every inch of the rim until you locate the damage. Once you’ve found it, use a brush to clean around the cracked area and extend another 2-3 inches beyond that point. Before proceeding with any repairs, it will ensure no dirt or debris is left in or around the cracked area.

Step 03: Crack Inspection

Once you have located the crack in your vehicle, it is important to clean it thoroughly before assessing how serious the damage is. Please take a closer look at the angle of the crack, as this can provide valuable information for fixing it as quickly and efficiently as possible. If you cannot detect any micro-cracks initially, it is still possible to drive your vehicle slowly until you can pinpoint the exact location and severity of the issue. These steps will help ensure your car remains in good condition and you can continue driving safely.

Step 04: Crack Cleaning

This step involves removing any excess debris or dirt around the crack so that it can be properly sealed later on. Ensuring that the area around the crack is clean and dry for any repair work to be effective is important.

To clean the crack, use a wire brush or sandpaper to remove any loose paint, rust, or debris from around the go. Then use a degreaser or rubbing alcohol to clean the area thoroughly. Once you have cleaned and dried the area, inspect it closely for any remaining cracks or damage.

Step 05: Make A Resin Mixture

All about making a resin mixture to bond and seal the crack. Here’s how you do it. Start by taking out the hardener tube and then the resin tube. Please read and follow instructions or safety precautions on both lines before using them. Once you have both lines ready, mix them until they form a uniform mixture. It would be best to stir the mixture continuously until you observe any colour change.

It’s important not to stop mixing after seeing that colour change since this ensures all components are mixed thoroughly. This resin mixture aims to create a strong adhesive that can effectively bind and seal the crack in your rim.

Step 06: Mixture Application

Fixing a cracked rim involves the application of an epoxy mixture to the damaged area. But before you do so, it’s important to use scrapers and slip them under the cross to secure them properly onto the cracks. Applying enough force is also necessary for the mixture to attach itself properly to the damage.
Cover the epoxy mixture at least 2-3 inches around the gap for better results. It will ensure no air leakage, and your rim remains firmly sealed even when exposed to harsh road conditions.

Step 07: Surface Drying

It is crucial to allow sufficient time for surface drying to achieve the best results when repairing rim cracks with an epoxy mixture. Attempting to drive your car immediately after applying the mix can make the situation worse, so it’s important to exercise patience. Leave the epoxy mixture to dry for at least 10-12 hours or, even better, overnight. It will give the combination enough time to create a strong bond that will effectively repair any cracks in the rim. By taking this approach and allowing ample time for drying, you’ll be able to restore your vehicle’s rims to their former glory.

Step 08: Attaching The Rim To The Wheel

It is time to attach the rim. This is a crucial step in the installation process and should be done carefully. It is important to refer to the manual provided by your car manufacturer to connect the rim correctly. Following the instructions will ensure that your new rims are safely secured to your car’s wheels and prevent any accidents or damage from occurring while driving.

Step 09: Recheck

After completing all the previous steps, performing a recheck is important to ensure the leak has been fully fixed. This step is necessary because if any air still escapes from the rim, other cracks or damages on the rim may need further attention.

To perform a recheck, you can use soapy water and apply it to the repaired area. If bubbles appear, the air is still leaking from the rim. You must repeat the steps until no bubbles appear when performing another recheck.

Reasons Behind A Cracked Rim: Know All To Apply Fix

Various factors can cause it. Understanding the reasons behind a cracked rim is crucial in preventing further damage to your vehicle and ensuring your safety on the road. I discuss some common reasons below:

Flat Tire:

A flat tire occurs when there is no air pressure in the tire, which can be due to various reasons such as a puncture, valve stem damage, or even just normal wear and tear. When a flat tire happens while driving at high speeds, it can cause the wheel to slam onto the pavement with force, leading to possible damage like cracking.

Potholes:

One of the primary reasons behind a cracked rim is hitting a pothole with force. Potholes can be deep enough to leave a dent in your car’s rim or even cause it to crack under pressure. The impact of hitting a pothole at high speeds can create enough force to bend or break your wheel, leading to further problems.

Curb Drive:

If you hit a curb hard or slide into it at high speed, there’s a good chance your rim will sustain damage. This can result in an unsightly crack on your wheel, which looks bad and dangerous.
Hitting a curb causes so much damage to your rims due to the force of impact. Even if you’re only going a few miles per hour when you hit the curb, the weight of your car plus gravity creates enough force to cause significant damage. The result is often a cracked rim that needs to be replaced or repaired.

Defective Wheels:

A cracked rim due to defective wheels is poor-quality material used in wheel manufacturing. Some manufacturers use low-quality materials that do not meet industry standards, leading to weaker rims that cannot handle stress. Another reason could be inadequate testing and inspection procedures at the factory level. If proper quality checks are not carried out during production, it can result in flawed rims that may crack under pressure. The age and mileage of your car can also contribute to a cracked rim caused by defective wheels.

How To Identify rim is Cracked?

To identify whether your rim is cracked, examine it closely. Look for any visible cracks on the surface of the rim or at the edges near the bolt holes. Use a flashlight and thoroughly inspect both sides of the wheel sidewall, as sometimes hairline cracks are hard to spot with the naked eye. I will tell you some common signs of identification for cracked rims:

Shaking Of Steering:

If you notice any shaking or vibration in your steering wheel, it’s important to have your rims inspected by a professional right away. A cracked rim can be dangerous, especially if left untreated for too long. It can lead to poor handling and control on the road, and it could eventually cause a blowout or tire failure while driving. To identify if your rim is cracked, start by visually inspecting it for any visible damage or cracks.

Imbalanced Tire Pressure:

If your car’s tires are losing air pressure frequently, it could indicate a crack in the rim. Unevenly distributed weight on a cracked rim can cause air to leak out faster from one tire than the other. This causes one tire to appear flatter than the other or for all tires to lose pressure at different rates.

Another way to identify a cracked rim is through visual inspection. A crack might not always be visible, but sometimes you may notice dents or deformities on the outer surface of your wheel. You might also notice damage around the valve stem or lug nut holes, indicating stress fractures caused by a broken edge.

Poor Handling:

Driving with a cracked rim can lead to poor handling of your car. The steering wheel shakes, and the tire pressure is unbalanced, making it difficult to control the vehicle. Turning while driving becomes impossible, especially when taking sharp turns. These situations put you in danger and endanger other drivers on the road. Therefore, ensure your rims are in good condition before hitting the road.

Expert Tips To Fix A Cracked Rim: Do It Perfectly

If It’s due to hitting a pothole or curb or perhaps from an accident, a cracked rim can be a real headache. With some expert tips, fixing your cracked rim can be done perfectly.

  • To begin with, inspect the extent of the damaged area. If the crack is small and superficial, it can easily be repaired by applying epoxy glue. If the crack is larger and deeper than 1/8 of an inch, it may require welding to fix it properly.
  • Next is removing any loose debris around the damaged area before sanding down and cleaning thoroughly around the rim. You must ensure that there’s no dirt left behind, as this will affect how well any filler material will adhere to the surface of your rim.
