I have relatively new tires on my car. The last few months, they have been losing air pressure, requiring me to refill them once or twice per month. Two questions:
- Why might this be happening? How do I fix it?
- I bought a portable air compressor. I can make out two different PSI numbers on each tire. How do I tell which is the right one? I’d tell you what the tire says, but it’s really difficult to read (I need a magnifying glass).
