Can radial and bias-ply tires be used together on a commercial vehicle?

Mixing radial and bias-ply tires on a commercial vehicle is not advisable due to the significant differences in their construction and performance characteristics. Radial tires have a different tread design and sidewall rigidity compared to bias-ply tires, leading to varying handling characteristics, ride quality, and stability. Using both types of tires on the same vehicle can cause uneven wear and compromise the vehicle’s performance, particularly in terms of handling and traction.

Furthermore, commercial vehicles often carry heavy loads, which increases the importance of consistent tire performance. If radial and bias-ply tires are used together, it can affect the steering and braking capabilities, potentially leading to unsafe driving conditions. For these reasons, it is a standard recommendation that tires of the same construction type be used on all axles of a commercial vehicle to ensure optimal safety and performance.
