Why do Subarus need all 4 tires replaced?

Why do Subarus need all 4 tires replaced?
Subarus typically require all four tires to be replaced at once due to their Symmetrical All-Wheel Drive (AWD) system. The AWD system in Subarus, as well as in other AWD vehicles like Audis and Lamborghinis, relies on the differential and computer working together to send the right amount of torque to each wheel to maximize control and minimize slippage. If one tire has a different size or tread depth than the others, it can cause the computer to take incorrect readings and put excessive strain on the differential, potentially leading to damage to the drivetrain. Therefore, to ensure optimal performance and prevent damage to the AWD system, it is recommended to replace all four tires at the same time on a Subaru .
It’s important to note that this recommendation may vary depending on the specific situation and the tread depth difference between the new tire and the remaining three tires. If the tread depth difference is within a certain range (typically around 2/32 to 3/32 of an inch), it may be possible to replace just two tires, as long as all four tires are the exact same model and size. However, if the tread depth difference exceeds this range, it is generally recommended to replace all four tires or have two new identical tires shaved down to match the tread depth of the worn tires.
In summary, while it may be possible to replace only two tires in certain circumstances, it is generally recommended to replace all four tires on a Subaru to ensure uniform tread depth and optimal performance of the AWD system [[9]].

Mismatching Tires May Cause Damage to Your AWD Vehicle
Replacing just one or two tires on an AWD vehicle could cause unnecessary wear and tear on your drivetrain, or confuse the traction control system to think that you are frequently losing traction.

Why do you have to replace all 4 tires?

Safety First: Tread Wear and Handling
Uneven tread wear can lead to reduced traction and stability, increasing the risk of hydroplaning or loss of control. By replacing all four tires, you ensure consistent tread depth and maximize your vehicle’s grip on the road.

What is better Bridgestone or Yokohama?

Bridgestone tires tend to be a bit more expensive than Yokohama tires, but they also tend to last longer. If you’re looking for a tire that will give provide you more value, Bridgestone is probably the way to go. Yokohama tires are known for being very quiet and comfortable.

How often should you replace tires on a Subaru?

about 3 years
How long do Subaru tires last? If your driving habits are basic and around 12,000-15,000 miles per year, an average tire’s tread will wear out in about 3 years. This could be longer if you commute less than 12,000 miles or less if you commute more aggressively.

Can you replace only 2 tires on a Subaru?

Your Subaru’s AWD system needs tires of uniform diameter and tread pattern to operate at peak performance. Subaru recommends replacing all four tires at once. However, if your remaining three tires are relatively new then you may be able to replace just one with the same brand, model, and size.

Is Michelin a better tire than Yokohama?

Michelin is a premium quality tire manufacturer. They arguably offer the best quality tire models across their product line more so than any other tire maker. Yokohama and Hankook are considered mid-level quality tires. However, they both offer some very good quality tire models for the money.
