Changing wheels is a common task in the maintenance of heavy machinery, trucks, and construction equipment. Whether you're replacing a worn-out tire or upgrading to a different type of wheel, understanding the right procedures and safety precautions is crucial. In this article, we’ll walk through the steps for changing wheels, highlight common challenges, and share practical tips to ensure the job is done correctly and efficiently.
Why Changing Wheels is Important
Changing wheels is essential to maintain the safety and performance of your equipment. Over time, wheels can wear out due to constant use, adverse weather conditions, or improper maintenance. Worn wheels or tires can lead to reduced traction, stability, and fuel efficiency. In some cases, improperly maintained wheels can even cause accidents or mechanical failures, making regular wheel checks and replacements crucial for operational success.
Tools and Equipment Needed
Before you begin, ensure you have the following tools and equipment to safely and efficiently change the wheel:
1. Safety First: Ensure Stability
Before starting, ensure the equipment is on level ground and that the parking brake is engaged. Place wheel chocks behind the wheels that are still on the ground to prevent movement.
If you’re using a jack, position it under a sturdy part of the machine or vehicle, such as the frame or axle. Avoid placing the jack under any soft or flexible components that might collapse under weight.
2. Loosen the Lug Nuts
Using a lug wrench or impact wrench, loosen the lug nuts on the wheel you intend to remove. It’s important to do this before lifting the vehicle or equipment, as the pressure of the wheel on the ground will make it easier to loosen the nuts.
Pro Tip: Loosen the lug nuts in a star pattern to ensure even distribution of force and prevent warping of the wheel.
3. Lift the Equipment
Once the lug nuts are loosened, use a jack to lift the machine or vehicle off the ground. Be sure to lift it high enough to remove the wheel and replace it with the new one. If you’re working with heavy machinery like excavators or skid steer loaders, make sure to use industrial lifting equipment to prevent accidents.
4. Remove the Old Wheel
After lifting the equipment, completely remove the loosened lug nuts and take the old wheel off. If the wheel is stuck due to corrosion or dirt, tap it lightly with a rubber mallet to break the seal. Always be cautious when handling heavy wheels, as they can be difficult to manage.
5. Mount the New Wheel
Align the new wheel with the wheel hub and slide it into position. Be sure that the wheel fits snugly onto the hub and that the holes align with the bolts or studs.
Pro Tip: When installing the new wheel, make sure that it’s centered properly to avoid imbalanced wear and unnecessary strain on the machine.
6. Tighten the Lug Nuts
Start by hand-tightening the lug nuts onto the wheel. Once they are hand-tight, use a torque wrench to tighten them to the manufacturer’s recommended torque specifications. Tighten the lug nuts in a star pattern to ensure an even fit.
Pro Tip: Avoid over-tightening the nuts, as this can damage the threads or distort the wheel, leading to instability.
7. Lower the Equipment
Once the lug nuts are properly torqued, use the jack to slowly lower the equipment back to the ground. Once the equipment is securely on the ground, double-check the lug nuts one more time to ensure they are properly tightened.
8. Test the New Wheel
Before fully engaging the equipment, take it for a short test run or drive. Pay attention to any unusual noises or vibrations that could indicate an issue with the wheel installation.
Common Challenges When Changing Wheels
1. Stubborn Lug Nuts
Lug nuts can sometimes be very difficult to remove, especially if they’ve been over-tightened or exposed to rust. If you encounter stubborn nuts, here are a few solutions:
If the wheel doesn’t align properly with the wheel hub, it can cause imbalances and lead to premature wear or even accidents. Ensure that the wheel studs and holes in the wheel are free from dirt, rust, or debris before mounting the new wheel.
3. Damage to the Wheel or Tire
Before mounting a new wheel, always inspect the new tire or wheel for any damage. A small crack or deformity can lead to larger issues down the line, including tire blowouts or wheel failure.
Maintaining Your Wheels: Tips for Longevity
To ensure that your wheels last as long as possible, perform regular maintenance checks and care:
A contractor working on a large construction project with a Bobcat skid steer loader noticed that one of the rear wheels had begun to show signs of wear and was emitting a noticeable squeaking sound. Upon further inspection, the wheel stud was found to be loose, causing the wheel to move slightly. After replacing the wheel and ensuring all lug nuts were torqued properly, the machine returned to normal operation.
This situation serves as a reminder that failing to inspect and maintain the wheels regularly can lead to more significant mechanical problems, resulting in costly repairs and potential downtime on the job.
Conclusion: Ensuring Safe and Efficient Wheel Changes
Changing wheels is a fundamental task that requires the right tools, safety measures, and knowledge. By following the step-by-step guide, addressing common challenges, and performing regular maintenance, you can ensure that your heavy machinery or vehicles continue to operate safely and efficiently. Proper wheel care not only prolongs the lifespan of your equipment but also contributes to a safer working environment.
Whether you're dealing with an excavator, loader, or heavy truck, always take the time to properly change and maintain the wheels to avoid performance issues and unnecessary downtime.

Tools and Equipment Needed
Before you begin, ensure you have the following tools and equipment to safely and efficiently change the wheel:
- Jacks or lifting equipment: To lift the vehicle or machinery off the ground.
- Lug wrench or impact wrench: For loosening and tightening the lug nuts.
- Torque wrench: To ensure the lug nuts are properly torqued to manufacturer specifications.
- Replacement wheel or tire: Make sure the replacement is the correct size and type for the machine or vehicle.
- Wheel chocks: To prevent the equipment from rolling while working.

Common Challenges When Changing Wheels
1. Stubborn Lug Nuts
Lug nuts can sometimes be very difficult to remove, especially if they’ve been over-tightened or exposed to rust. If you encounter stubborn nuts, here are a few solutions:
- Use penetrating oil: Apply WD-40 or another penetrating oil to the lug nuts and let it sit for a few minutes before attempting to loosen them.
- Use a breaker bar: A breaker bar provides extra leverage, making it easier to loosen the nut.
- Heat: If necessary, heat the lug nut with a torch to expand the metal, making it easier to loosen.
If the wheel doesn’t align properly with the wheel hub, it can cause imbalances and lead to premature wear or even accidents. Ensure that the wheel studs and holes in the wheel are free from dirt, rust, or debris before mounting the new wheel.

Maintaining Your Wheels: Tips for Longevity
To ensure that your wheels last as long as possible, perform regular maintenance checks and care:
- Check for wear: Periodically inspect the tires for signs of wear, such as uneven tread patterns or bulges.
- Inflate tires properly: Keep the tires properly inflated to prevent unnecessary wear and improve fuel efficiency.
- Rotate tires: Just like vehicle tires, rotating the wheels regularly helps to ensure even wear.
