Almost 5K miles, and the tires look like new. I was surprised to see you calling out 29 to 32 when the cold spec is 35front/36rear.
I also check the tires with a gauge, cold, at least once a week. I'd guess that I'm taking out the tire pump for a couple of quick pumps a couple of times a month. As Jaime said, "trust but verify" (also applies to the oil - I don't depend on just the instrument gauge, but use the dip stick, once a week, right after a ride.). I also use the trip 1 gauge as a back-up to the fuel gauge. Trip 1 gets reset at every fueling stop. I know that I get pretty a consistent 55 MPG so when Trip 1 hits 150 miles since the last fill-up, I'm looking for a gas station (yes, with plenty of safety factor built into that calculation).
