tires
reading the sidewall of your tire you will notice it says something like max 45 psi or something close enough to that. Atmospheric pressure at sea level is about 15 psi. So if you took a tire inflated to 45 psi into space the 15 psi pushing in would be gone and youd be left with the absolute pressure in the tire relative to the vacuum which is 45+15=60 psi. The tire might pop at that increased pressure. Or you could just inflate it to 30psi (gage pressure) at sea level, so that the absolute pressure relative to the vacuum of space would be 45 psi (absolute pressure) and within the material tolerances so it wouldnt pop.
