Since the emergence of the tuning fashion approximately two decades ago, car wheels have become a significant aspect of aesthetic modifications. In the past, having a spoiler, metallic paint, stickers, a big exhaust, and good tires was the epitome of the car enthusiast community, particularly those interested in 1/4 mile races.
In today’s automotive landscape, wheel rim sizes continue to grow. Previously, manufacturers released cars with standard 15-inch wheels, but now the same car models are equipped with 20-inch and 22-inch wheels. If your car still has smaller wheels compared to the current trend, is it advisable to increase their size?
Advantages and Disadvantages of Large Wheels on Cars
There are numerous advantages and disadvantages associated with this aspect, depending on the type of car being driven. Aesthetically, increasing the rim size may not always enhance the overall appearance, as it can alter the original design of the vehicle.
Advantages of Having Large Wheels
- Improved stability: Wider tires provide better weight distribution and balance during driving.
- Enhanced cornering and steering precision.
- Superior grip and braking capacity due to increased contact surface with the road.
- Heightened sensitivity on the steering wheel, allowing for better road feedback. Any issues with the front end will be more noticeable.
- Customizable sporty appearance with the option to stand out from the crowd.
Disadvantages of Increasing Wheel Size
- Higher cost: Larger wheels require wider tires with low-profile characteristics, making them more expensive than standard wheels.
- Less comfortable driving experience: Low-profile tires offer less air diameter to cushion the contact with the road, resulting in feeling more road irregularities through the steering wheel.
- Increased risk of damage: Being closer to the ground, larger wheels are more susceptible to friction, scratches, and impacts with curbs or objects on the road.
- Higher fuel consumption: Larger tires cover more surface area, leading to up to 24% increased fuel consumption compared to standard tires on the same car.
According to a study conducted by the United States Environmental Protection Agency (EPA), switching to larger tires can result in a fuel consumption increase of over 20%. The test was performed on a Tesla Model S, which saw a 4.9% increase in consumption when changing from 19-inch to 21-inch wheels. Other models experienced even worse consumption, particularly heavier vehicles that showed an increase of over 20%.
This means that if you prefer larger wheels, you can opt for them, but you should be aware of the consequences, such as increased expenses for fuel consumption and the higher cost of new tires.

Aesthetic options: Larger wheels offer more room for unique designs, such as intricate spoke patterns or custom finishes.
Disadvantages of Having Large Wheels
- Ride comfort: Larger wheels with low-profile tires can result in a firmer and less comfortable ride, as there is less cushioning from the tires.
- Increased vulnerability to damage: Larger wheels are more prone to damage from potholes, curbs, and other road hazards.
- Reduced fuel efficiency: The added weight and increased rolling resistance of larger wheels can negatively affect fuel efficiency.
- Increased cost: Larger wheels tend to be more expensive to purchase and maintain, including the cost of tires.
- Added strain on suspension and braking systems: Larger wheels can put additional stress on the suspension and braking components of a vehicle, potentially leading to increased wear and tear or decreased performance.
Ultimately, the decision to increase the size of your car’s wheels should consider both the aesthetic appeal and the potential impact on performance and comfort. It is advisable to consult with experts or professional tuners to determine the best wheel size for your specific vehicle and driving needs.
What are some of the potential disadvantages of having larger wheels on a car?
1. Increased cost: Larger wheels generally come with a higher price tag compared to smaller ones. This can add to the overall cost of the car, especially if they require special tires or modifications to accommodate the larger size.
2. Reduced fuel efficiency: Larger wheels are typically heavier, which can increase rolling resistance and require more energy to move the car. This can result in decreased fuel efficiency and higher fuel consumption.
3. Harsher ride quality: Bigger wheels often have thinner sidewalls, resulting in less tire cushioning and reduced ability to absorb road imperfections. This can lead to a rougher and less comfortable ride, especially on uneven or bumpy roads.
4. Increased risk of damage: Larger wheels are more susceptible to damage from potholes, curbs, or other road hazards. The overall diameter of the wheel also affects the clearance between the tire and the car’s body or suspension components, increasing the risk of scraping or hitting obstacles.
5. Increased braking distance: Due to the larger diameter, larger wheels can result in increased rotational inertia and require more effort for the brakes to stop the car. This can lead to longer braking distances and potentially compromise safety.
6. Limited tire options: Larger wheels may have a smaller selection of tire options available compared to standard sizes. This can make it more challenging to find suitable tires for specific driving conditions or preferences.
7. Reduced acceleration and performance: The added weight of larger wheels can negatively impact the car’s acceleration and overall performance. The engine may need to work harder to overcome the increased rotational inertia, resulting in slower acceleration and decreased responsiveness.
