Tire pressure during storage
I'm kind of a fair weather rider. I live in Illinois and generally speaking, I don't ride my bicycle between the months of November-February. It sits dormant in my garage for about 4 months each year. For preventative maintenance have always gone out to the garage every 2-3 weeks during those months and topped off the air pressure in my tires but I'm wondering if that is really necessary.
Will letting my tires and tubes go flat over the winter cause any damage to the tires, tubes, or the bike itself?
