How Cold Weather Affects Tire Pressure — and Why It Matters for Subaru Drivers
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.
