Winter brings plenty of challenges for drivers, but one issue often goes unnoticed until a warning light appears on the dashboard: dropping tire pressure. As temperatures fall, the air inside your tires becomes denser, lowering PSI. For every 10‑degree drop in temperature, tire pressure can fall by about 1–2 PSI. That may not sound like much, but for Subaru drivers—whose vehicles rely on precise, balanced traction—it makes a meaningful difference.

How Low PSI Impacts Subaru's AWD System
Subaru's Symmetrical All‑Wheel Drive system is engineered to distribute power evenly across all four wheels. This design gives Subaru vehicles their signature stability and control, especially in snow and ice. But the system works best when all four tires are inflated to the recommended PSI. If even one tire is significantly underinflated, it can throw off the AWD system's balance, leading to uneven wear, reduced traction, and less predictable handling on winter roads.
Fuel Efficiency and Tire Wear in Winter
Low tire pressure also affects fuel efficiency. Under‑inflated tires create more rolling resistance, forcing your engine to work harder. In cold weather, when fuel economy already tends to dip, this added strain can make a noticeable impact.
Stay Confident On Winter Roads
For Subaru drivers, staying ahead of tire pressure changes is one of the simplest ways to maintain safety and performance all season long. Checking your tire pressure regularly, especially after significant temperature swings, helps ensure your vehicle handles the way it was designed to.
Winter driving demands confidence, and properly inflated tires are a key part of that equation. By keeping an eye on tire pressure throughout the colder months, Subaru owners can protect their AWD system, improve fuel efficiency, and stay safer on icy, unpredictable roads.
