How often / Check Tire Pressure
I do check mine before heading out, but if I am gone a week I don't check them again till the next trip.

I must be lucky or something. I have GY Marathons and they never leak air. They're 3 seasons old and after their winter nap of about 4-5 months they're still at 64-65psi. Every time I check before a trip they're at 64-65psi. So for me I don't check them before every trip. I may go 2-3 times with out checking them.
