Will changing tire size result in a fine?
2 Answers
Changing tire size can lead to fines. Large rims and small rims differ in appearance and fuel consumption. Appearance: Vehicles with large rims tend to look more imposing and sporty, especially for certain sedans, where this effect is particularly pronounced. Additionally, larger rims provide higher driving stability, especially at high speeds, making the driver feel the vehicle is very steady without any sense of drifting. In contrast, vehicles with small rims exhibit the opposite characteristics. Fuel Consumption: Smaller car tires can more effectively release power, thereby reducing the vehicle's fuel consumption. For owners who prioritize comfort and quietness, the tire noise of smaller rims is naturally lower compared to vehicles with larger rims.
I've been driving for many years, and changing tire sizes can indeed result in fines, especially if the modifications are too significant. The law stipulates that tires must conform to the vehicle's factory specifications, primarily to avoid safety hazards. Excessive changes in tire diameter can affect the accuracy of the speedometer, potentially increase braking distances, or cause instability when turning. I once saw a friend who modified his tires without authorization and failed the annual inspection while also getting fined—police can issue tickets directly if they spot irregularities during roadside checks. Fines vary, starting from a few hundred yuan in some areas. To avoid such trouble, it's advisable to check the vehicle's manual before making changes, ensuring the new tire's outer diameter variation stays within ±3%. It's best to have them installed professionally to match the rim size. Safety comes first—don’t break the rules just for a temporary cool look.
