Howle’s Hints: Trailers Under Pressure

Can you handle the pressure? During the winter, the pressure in your truck and boat trailer tires can change quite a bit. Since air is a gas, it expands when warm and contracts when cold. Cold days mean lower air pressure. You can lose up to five psi (pounds per square inch) when winter’s icy temperatures hit. This can affect handling and durability of your tires. The rule of thumb is for every 10 degree change in air temperature, the tire’s inflation will change by around one psi, so check your pressure and air up when needed.
