Proper cold weather tire inflation practice?

To maintain proper tire inflation in cold weather:

Check tire pressure regularly, especially as temperatures drop significantly to maintain recommended levels; typically found on the placard at the driver's door sill or in the owner's manual.

Do not reduce tire pressure in winter assuming it enhances traction as it negatively impacts performance and safety.

Add only recommended inflation; using nitrogen to fill your tires can help retain optimal tire pressure as it doesn't undergo substantial expansion or contraction due to temperature variations compared to regular air.
