請問subaru的車如果要換輪胎,有一定要四輪一起換嗎?
可以只換前面兩輪,或者只換後面兩輪,
甚至只換一輪.
不同的換法,對車子各有什麼不好的影響?

Matching Tires on Four-Wheel Drive and All-Wheel Drive Vehicles
Subaru Service Center
Why Do I Have To Replace All 4 Tires On My Subaru at the Same Time?
"All Subaru vehicles are equipped with symmetrical all wheel drive. This drivetrain system is a complex system of gears and fluid pressure that allow the proper amount of power to be distributed to each of the wheels. As a result all tires that are on the vehicle must be within 3/32 tread depth in order to prevent damage to the drivetrain. Any difference in tread depth that is 3/32 or greater will result in the circumference of the tires being different. When the tire circumference is different, the components of the drivetrain will rotate a different speeds resulting in stress and binding in the drivetrain. This internal stress can cause premature deterioration of the components of the drivetrain and could potentially void the vehicle warranty."
