You do now
Use something like this: https://smile.amazon.com/Accu-Gage-PSI-Dial-Tire-Gauge/dp/B00070KA5I (found at any auto parts store, walmart, target, etc...) to check your pressure.
You can fill it at any gas station, often for a small fee, or it would probably be worthwhile for you to pick up a small compressor, even one that plugs into your car's 12v source.
All that being said any auto/tire shop can top your air pressure up, I doubt any would charge for that.
