How low of a tire pressure can you safely run your radial tires at?

It's generally recommended to maintain tire pressure within the manufacturer's specified range, usually found on the driver's door jamb or in the owner's manual. Running radial tires significantly below the recommended pressure can lead to reduced handling, increased tire wear, and a higher risk of blowouts. A safe minimum pressure is typically around 20% lower than the recommended pressure, but it's best to avoid going below the manufacturer's specifications. Regularly checking and maintaining proper tire pressure is key for safety and performance.
