What are the effects of changing to wider tires on a car?

[MacJoel]

If you purchase an economical, low-performance car and change to wider tires, the grip will increase, but so will the resistance. It is very likely that the car will experience insufficient power due to the wider tires. Below are the factors related to the impact on a car's performance: 1. Engine: The engine parameters that affect performance include maximum power, maximum torque, and the shape of the engine's external characteristic curve. 2. Influence of the final drive ratio: The selection of the final drive ratio mainly considers the car's purpose and the road conditions it frequently encounters. 3. Influence of the transmission ratio: This includes the minimum and maximum transmission ratios, as well as the proportional relationship between the gear ratios of the transmission. 4. Influence of the car's aerodynamics: The air resistance coefficient of the car affects its performance. Aerodynamics has a significant impact on the performance and fuel economy of high-speed cars, but it has little effect on the maximum road resistance the car can overcome.
