The Importance of Replacing Subaru Tires in Pairs for Optimal Safety and Performance

Subaru vehicles are known for their dependability, reliability, and safety features. They provide a smooth and seamless driving experience that leaves the driver feeling confident behind the wheel. One key aspect of maintaining a safe and reliable Subaru vehicle is by replacing the tires in pairs, rather than individually.

Why Do Subaru Tires Need to be Replaced in Pairs?

Tire replacement is vital for the safety and performance of any vehicle. However, it is especially crucial for Subaru cars as they use an all-wheel-drive system, which means the tires need to be able to work together seamlessly. Using mismatched tires on a Subaru could lead to uneven wear and tear and affect the car’s handling, stability, and overall safety.

When one tire is replaced, it affects the other tire’s wear and tear. Their structure and pattern will be different, leading to potential safety hazards, including reduced braking performance, tire blowouts, and skidding on wet or slick roads. Thus, replacing one tire can cause the new and old tires to have different tread depths and patterns which can seriously affect the car’s handling and pose dangers on the road.

How to Determine Tire Replacement?

One of the most common signs of tire wear is the tread depth. The minimum legal depth should be at least 1.6mm across the entire tread width of the tire. However, for optimal safety, it is recommended to replace the tires when the tread depth is 2mm or less.

Tire wear has other indicators apart from the clear physical signs. These can include vibrations felt through the steering wheel or the car’s overall body, particularly on high-speed drives, instability of the car when cornering, and the "pulling" effect when braking or accelerating. If any of these signs are observed, it is essential to have a mechanic check the tires for wear and recommend whether replacing them is necessary.

The Risks of Not Replacing Subaru Tires in Pairs

As previously mentioned, using mismatched tires on a Subaru can significantly impact vehicle safety and performance. When tires have different treads, depths, or patterns, they tend to react differently on different road surfaces. This variance can easily compromise the handling and stability of a vehicle, causing it to veer off the road or spin out of control on slick pavements. Moreover, tire damage repair can be expensive, so it pays to buy new tires in pairs to avoid unnecessary costs and safety risks.

Not replacing Subaru tires in pairs could also affect the car’s suspension, leading to more extensive damage and more repair costs in the long run. Suspension systems work by distributing the car’s weight equally between all four tires. If the tires are not matched in size, the suspension system has to work harder to keep the car stable, which can put it under unnecessary stress.


In conclusion, replacing Subaru tires in pairs is vital for maintaining optimal safety and performance. Doing so ensures that the tires work together seamlessly, providing drivers with a smooth, comfortable, and safe driving experience. It is also a cost-effective and practical solution that avoids unnecessary expenses and safety risks down the road. Whether you do it yourself or hire a professional mechanic, properly maintaining your Subaru’s tires in pairs is an investment worth making for a safe and reliable driving experience.
