## How to Calculate Wheel Torque

Wheel torque is a measure of the force that is applied to a wheel to rotate it. It is typically measured in newton-meters (Nm) or foot-pounds (ft-lb). Wheel torque is an important factor in determining the performance of a car, as it affects acceleration, top speed, and fuel efficiency.

There are two main ways to calculate wheel torque:

1. Using a dynamometer: A dynamometer is a device that measures the torque and power output of an engine. To calculate wheel torque using a dynamometer, the car is placed on the dynamometer and the engine is run at different speeds and loads. The dynamometer measures the torque and power output of the engine, and the wheel torque can be calculated from this data.
2. Using a torque wrench: A torque wrench is a tool that measures the torque applied to a bolt or nut. To calculate wheel torque using a torque wrench, the torque wrench is attached to the wheel lug nuts and the lug nuts are tightened to the specified torque. The torque wrench will measure the torque applied to the lug nuts, and the wheel torque can be calculated from this data.

### Factors that Affect Wheel Torque

The following factors can affect wheel torque:

Engine power: The more powerful the engine, the more torque it can produce.
Transmission: The transmission can affect the amount of torque that is delivered to the wheels. A transmission with a lower gear ratio will produce more torque than a transmission with a higher gear ratio.
Differential: The differential can affect the amount of torque that is delivered to each wheel. A differential with a lower gear ratio will produce more torque to the wheels than a differential with a higher gear ratio.
Tires: The tires can affect the amount of torque that is delivered to the ground. Tires with a larger contact patch will produce more torque than tires with a smaller contact patch.

### How to Improve Wheel Torque

The following tips can help to improve wheel torque:

Increase engine power: Increasing engine power will increase the amount of torque that the engine can produce. This can be done by installing a turbocharger, supercharger, or other performance modifications.
Change the transmission gear ratio: Changing the transmission gear ratio can affect the amount of torque that is delivered to the wheels. A lower gear ratio will produce more torque than a higher gear ratio.
Install a limited-slip differential: A limited-slip differential can help to improve traction and deliver more torque to the wheels.
Upgrade the tires: Upgrading the tires can help to improve traction and deliver more torque to the ground. Tires with a larger contact patch will produce more torque than tires with a smaller contact patch.

### Conclusion

Wheel torque is an important factor in determining the performance of a car. By understanding the factors that affect wheel torque and by taking steps to improve wheel torque, you can improve the performance of your car.
