What are the impacts of upgrading to larger car wheels?

The impacts of upgrading to larger car wheels include increased fuel consumption, heavier steering, improved tire grip, clearer road feedback and better stability at high speeds, as well as potential issues during annual inspections. More details are as follows: 1. Tire width also affects resistance; wider tires create more resistance, leading to higher fuel consumption and slower acceleration. Therefore, blindly widening tires is not advisable—vehicle power and economic performance must be balanced. 2. Tire sidewall height, commonly referred to as "thick tires" or "thin tires," mainly affects shock absorption and handling. Thicker tires provide better shock absorption, filtering out minor vibrations more effectively, while thinner tires offer less vibration damping, resulting in more direct feedback. However, thick tires can make handling feel sluggish and reduce steering precision, which is why high-performance cars and sports cars tend to use thin tires. 3. For better handling, larger wheels must be made lighter using advanced manufacturing techniques and materials, inevitably driving up costs. Moreover, when wheel sizes reach levels like 19 or 20 inches, not only do tire prices surge, but the available brands and styles also become increasingly limited.
I recently upgraded my car with larger rims, and the overall change is quite noticeable. In terms of appearance, the car instantly looks cooler and more sporty, turning heads on the road and boosting my confidence. Regarding handling, the larger rims paired with low-profile tires have indeed improved grip, making turns more stable and reducing the floaty feeling at high speeds. However, comfort has taken a big hit—small bumps or speed bumps feel much harsher, and rear passengers often complain about the ride being uncomfortable. Fuel consumption has also increased slightly; my car used to average around 7 liters per 100 km, but now it's nearly half a liter more, especially noticeable on long highway drives. On the safety front, braking performance has improved a bit, stopping faster, but the low-profile tires are more susceptible to road conditions, like potholes or rocks, increasing the risk of blowouts. Maintenance costs are higher too, as larger tires need replacing more often, and the suspension system requires extra checks during servicing to avoid overloading. All things considered, upgrading to larger rims enhances looks and driving dynamics, but you have to weigh the trade-offs in daily comfort and expenses.
