When traveling across the country my sealed Pringles can lids bow and dip. How will my sealed beer bottles handle this?

They will be fine, bit of difference in a beer cap and a plastic Pringles top.

There is also a bit of a difference in the pressure already inside a beer bottle and the pressure already inside a pringles top.

The method of transporation was not mentioned but it doesn't make that much difference whether you drive through the "Mile High City" or fly over it as cabin pressure altitude in most aircraft is about 7000 feet. That means that the outside of the beer container will be at a pressure 2.5 - 3.5 psi lower than at sea level. Assuming 2.8 vols. of CO2 in the beer and that it's hot - 86 °F (because that's as high as the chart goes) the pressure inside the bottles will be 64.7 psia. At sea level that will be 50 psig (the pressure trying to blow the cap off) and in an airplane with cabin pressure altitude of 7000 feet, 53.5. In the vaccum of space it would only be 64.7. IOW the most the pressure can increase (bottle in a vacuum), relative to sea level is 14.7 psi or 29.4%. Since the area of the mouth of a beer bottle is 0.44 in^2 that means the pressure on the cap woul be 6.5 pounds greater in an aircraft experiencing explosive decompression at 50,000 ft than at sea level.

You were the one giving the teacher an apple in class weren't you???

AJ is a fawkin MAAUUN!

I bet he could talk the pants off a hot coed with that description! Or at least calculate the required decrease in the coefficient of friction of the waistband on her panties against her skin before they succumbed to gravity!
