Why do Subarus need 4 new tires?

Why do Subarus need 4 new tires?
When it comes to Subarus, there are situations where it is recommended to replace all four tires, even if only one tire is damaged or worn out. This is particularly important for Subarus with all-wheel drive (AWD) systems. The reason for this is that all four tires on an AWD Subaru must have the same tread depth and type to ensure proper functioning of the AWD system and to prevent damage to the transmission. If there is a significant difference in tread depth between the new tire and the remaining three tires, it can cause issues with the AWD system and potentially lead to transmission damage.
Additionally, it is important for the tires to have the same type of tread design. If a tire is no longer available or not offered locally, and you have a blowout, you may need to buy four new tires to ensure they all have the same tread design. However, some tire shops offer a service called tire shaving, where you can buy one new tire and have it shaved to match the tread depth of the other tires on your car.
It’s worth noting that tire wear and alignment can also affect the performance and safety of your Subaru. Regular tire rotation and wheel alignment are important to ensure even wear and optimal performance. Uneven tire wear can lead to differences in tire size, which can further impact the functioning of the AWD system.
In summary, while it may seem excessive to replace all four tires when only one is damaged or worn out, it is recommended for Subarus with AWD systems to maintain consistent tread depth and type across all four tires to ensure proper functioning of the AWD system and to prevent potential damage to the transmission.
