How many inches can the 17-inch wheels of Audi A6L be modified?
Cars are man-made, so they can definitely be modified, but there are too many things to change. 17 inches was changed to 19 inches, which is a full "2 inches" higher. The chassis suspension needs to be modified in many places. And it may bring more disadvantages:
The tires become "higher", the center of gravity moves up, and the "stability" becomes worse.
Due to the factory design of the vehicle, it is possible that certain components may interfere with each other due to the increase in tire size. It will cause inconvenience when turning or the steering may not be in place.
The braking distance (or effective braking distance) may change due to the upward shift of the center of gravity. If the effective braking distance becomes longer, it will bring hidden dangers to safety.
As the size increases, the tire width may increase, so the frictional resistance will increase accordingly. Vehicle fuel consumption increases.
The instrument-related parameters display abnormally. Due to the change in tire size (heightening), there is a difference in speed ratio, which may cause the instrument-related parameters to display abnormally. , as shown in speed.
Due to the size change of the steering mechanism and chassis suspension mechanism, the sensitivity of the driving or mechanism transmission, relative movement and action of the actuators, components, etc. is lower than before the change. Variation or hysteresis (execution) also brings hidden dangers to safety.
Due to the transfer and conversion of kinetic energy and its effect on the tire, it is possible that the enlarged tire will wear faster or even be scrapped in advance (the tire will not reach the maximum strength of the tire). Best transmission or rotational force).
If the tire is enlarged, it will be heated by the centrifugal force during driving. The amount becomes larger (because the effective braking distance becomes longer), and at the same time, the braking system, such as the brake shoes, generates a lot of heat, which may cause pre mature wear and scrapping of the bearings or related parts, and the skin is softer during braking. ", "cannot stop" and other phenomena, or even brake failure.
We do not rule out the possibility of causing other defects. The specific judgment will be based on the actual vehicle assembly or modification.
It is not recommended to modify or modify any safety parts or parts of the vehicle involved, including tires, to ensure driving safety and the three-guarantee after-sales warranty period. personal rights within.
