Why Is the Steering Wheel of Large Vehicles Not Straight?

[ErinFitz]

Reasons for the steering wheel of large vehicles not being straight: Low tire pressure: Low tire pressure increases the contact area between the tire and the road surface, leading to greater friction and making steering more difficult, which results in an off-center steering wheel and compromises driving safety. Steering gear or power steering pump failure: Issues with the steering gear and power steering pump can also cause the steering wheel to be off-center. Any malfunction in these critical components can make steering difficult. Problems such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked. Toe-in malfunction: Toe-in also plays a role in vehicle steering. It helps the steering wheels self-align, ensuring stable straight-line driving. Therefore, any issues in this aspect can lead to an off-center steering wheel.
