Wider and thicker tires consume more fuel - not recommended for ordinary car owners to modify unless necessary

When it's time to replace the tires, car owners often like to switch to wider and larger ones. Maintenance personnel warn that modifying tires can easily lead to increased fuel consumption, and improper modifications may also cause safety issues.

Thicker and wider tires can increase fuel consumption

Reporters found that since tires are not covered by the manufacturer's warranty, many car owners prefer to choose auto beauty shops with lower prices for tire replacement. Due to the aesthetic appeal of larger and thicker tires, many car owners tend to opt for these more visually pleasing options when replacing their tires.

The manager of an auto beauty shop on Huayuan East Road, named Awei, told reporters that larger and wider tires offer better grip. However, due to the increased contact area of thick and wide tires, the friction resistance increases, leading to higher fuel consumption as well. Additionally, thick and wide tires usually have deeper treads, which directly affects the vehicle's fuel efficiency. Moreover, the selection of tires must be appropriate; otherwise, it could compromise driving safety. In tire design for vehicles, there is generally enough turning space allocated for the front wheels. However, excessively wide tires might interfere with the steering mechanism in some cars, potentially causing insufficient or excessive steering.

Therefore, if the modification is not reasonable, it may also cause abnormal wear on both the tires and the suspension system. Meanwhile, the size of the tires that a modified vehicle can accommodate should be scientifically matched according to factors such as the engine's actual power output, which is a very rigorous process.

Maintenance staff pointed out that in recent years, automakers have placed great emphasis on reducing fuel consumption. When each car leaves the factory, its tires are matched based on factors such as the vehicle's weight and engine displacement to ensure optimal performance. Only in this way can the vehicle perform better according to the fuel consumption data published by the Ministry of Industry and Information Technology. Therefore, when replacing tires, unless there are special reasons, it is recommended that car owners choose tires that match the original rims.
