tire pressure question

We recently bought an '04 Sienna LE (just before a road trip) & we love this van, but I have a question about the tires.

Now I feel a little silly, because though I'm not professional mechanic, I do have some experience on cars (minor stuff like changing transmission filters, wheel bearings etc) So I'm not a total doofus...but here goes:

I've checked our tires with two different gauges. I get "cold" readings of 35 psi on all four tires, but the front tires look bulged out like they're low, at least to me. I know the front is the heavier part of the vehicle and all but this just doesn't look right to me. See the attached picture & tell me what you guys think.

Is this just the way this vehicle sits or should I get new tire gauges?
Thanks,

I have been deceived by looking at my tires and when I asked at the tire store, they said that's why you buy a tire pressure guage! Looking doesn't tell you anything
