Should the Handbrake Be Applied When Changing a Spare Tire?

[MacReagan]

When changing a spare tire, the vehicle should be in park and the handbrake should be applied. Same Specifications: Tires of different specifications have different outer diameters and section widths when inflated, resulting in uneven load distribution when mounted on the same axle. Same Structure: Due to the different carcass structures of radial tires and bias tires, their cushioning performance and circumferential deformation vary. Mixing these two types of tires on the same axle will inevitably lead to uneven load distribution and inconsistent wear. Same Material: Material mainly refers to the carcass cord material. For example, all-steel radial tires and fiber radial tires have significant differences in carcass thickness, cord strength, and heat dissipation performance, which can affect performance when mixed.
