Larger Wheels: Benefits and Potential Hazards for Your Car
When considering upgrading your car with larger wheels, it's important to weigh the potential benefits against the possible drawbacks. This article explores the advantages and disadvantages of using larger wheels than the stock size, providing practical insights for car enthusiasts.
Can Using Larger Wheels Be Harmful?
The short answer is yes. Using wheels that are larger than the stock size can indeed be harmful. There are several key issues to be aware of, including reduced fuel efficiency, strain on the suspension, changes in handling, and possible inaccuracies in the speedometer readings. Additionally, improper fitting can lead to increased tire wear and damage to various components of the car.
Impact on Car Geometry and Performance
Cars and pickups are designed with specific tire sizes and offsets in mind. Changing the wheels or tires can alter the geometry and apply stress to the components, potentially causing them to fail faster than usual. While in some cases the upgrade can be achieved with minimal impact, significant changes such as adding large wheels on top of a lift kit require careful consideration and potentially additional upgrades to other parts of the vehicle.
Common Issues and Their Solutions
Upgrading to larger wheels can lead to several issues:
Slower Acceleration and Reduced Braking Power
Due to the increased outside diameter of the wheel and tire combo, the acceleration may become slower. The added weight may also reduce the braking power of your car. Furthermore, if the new wheels result in reduced clearance, it can lead to potential contact with steering suspension or body components, especially during sharp turns or when hitting bumps or train tracks.
Wheel Offset Considerations
Another critical factor is the wheel offset. A larger offset can increase pressure on the wheel bearings, making the car handling less stable. The increased distance between the tire and the wheel hub can result in higher stress and reduced clearance. You might be able to maintain the same outside diameter by using a smaller profile tire, but this will likely affect the ride and increase the replacement cost and difficulty.
Resales and Maintenance
When it comes to reselling your car, owners with custom rims and tires may face some challenges. Custom rims that do not match the original style can be difficult to find a matching set or to replace if one becomes damaged. Additionally, maintaining and finding compatible parts for your car may become more cumbersome.
Conclusion and Practical Advice
While switching to larger wheels can enhance certain aspects of your car, such as slightly increased traction and more space for larger brake rotors, it is crucial to carefully evaluate the potential drawbacks. Ensure that the wheels are properly fitted and that necessary upgrades are made to maintain the vehicle's performance and safety. If you decide to go ahead with the upgrade, keep the original rims and tires in storage as a backup for future resales or unforeseen issues.
