Can sedan tires be enlarged?
2 Answers
Sedan tires cannot be enlarged as it will affect the annual inspection and increase fuel consumption. The tires are the only components of a car that come into contact with the ground, playing a crucial role in driving stability and safety. Therefore, car owners should not arbitrarily change the specifications and sizes of the tires. The functions of tires include: 1. Supporting the entire weight of the vehicle and bearing the load; 2. Transmitting traction and braking torque to ensure adhesion between the wheels and the road surface; 3. Reducing and absorbing vibrations and impacts during driving, preventing severe vibrations and premature damage to car components; 4. Adapting to the high-speed performance of the vehicle, reducing driving noise, and ensuring driving safety, handling stability, comfort, and energy efficiency.
I once modified the tires on my friend's sedan, and after upsizing, I felt a slight improvement in the car's handling with better grip, especially on wet roads. However, you need to pay attention to wheel compatibility during the modification. If the tires are too large, they might rub against the suspension or body, and at higher speeds, the speedometer could become inaccurate because the actual speed would be lower due to the changed wheel circumference. Additionally, fuel consumption will definitely increase. I tried a 15% size increase, and it added over one liter per 100 kilometers. If you're serious about modifying, I recommend not exceeding the manufacturer-approved size range and consulting a professional shop for an evaluation to avoid any issues. Balancing driving experience and safety is crucial.
