Since my jeep is also my daily, I'm kind of OCD about keeping my tire pressures where I like them. Generally, I check them once a week. During the holidays, the jeep sat for a month. I just recently started commuting in it again and checked the pressures. I lost 5lbs. equally across all four. Is that much loss a common thing with bigger tires like that? My other 2 vehicles don't lose hardly one pound over time.
