Why do the tires on my little used vehicle lose pressure?
This happened to my truck too. I couldn’t make it stop happening, but I did find a solution to the “I don’t want all my tires to go flat” problem. I got a small air compressor that plugs into the cigarette lighter that just stayed in the truck. I invested about 10-15 minutes of air pumping time before I drove it. They’re cheap as hell [like $10-20 really] and can save a lot of heartache dealing with low possibly risky tires.
How do tires lose pressure? Tires lose pressure naturally through the process of permeation. Changes in outdoor temperature can affect the rate at which tires lose air. This change is more pronounced in hot weather. Generally speaking, a tire will lose one or two pounds of air pressure per month in cool weather or even more in hot weather. Remember, underinflation is the leading cause of tire failure, so check inflation pressure regularly.
