Why trucks have 6-8 tyres?

Trucks have 6-8 tires primarily for stability, load distribution, and safety. The larger number of tires helps evenly distribute the weight of heavy cargo, reducing the risk of tire blowouts and improving traction on various road conditions. Additionally, having multiple tires enhances the vehicle's ability to navigate tight turns and uneven surfaces, which is crucial for heavy-duty vehicles that operate in diverse environments. This design also contributes to better braking performance and overall vehicle control.
