Should I Lower Tire Pressure in the Winter?
For most drivers, the answer is no: winter tire pressure should usually match the manufacturer’s recommended cold pressure, checked regularly because tires lose pressure as temperatures fall. Lowering pressure may make sense only in specific low-speed situations, such as driving through deep, soft snow off-road or trying to free a stuck vehicle. Before adjusting, weigh the risks of underinflation against traction needs, and consider safer alternatives such as winter tires or tire chains.
