First, remove the cap that covers the end of your valve and put it somewhere safe. Check the sidewall of your tire before pumping: It should list the PSI range that your tire can safely handle. Use the AstroAI Tyre Inflator to set your ideal bike tire pressure. Next, attach the inflator to an air compressor using the NPT connector. Find the compatible air chuck that comes with the AstroAI tire inflator and attach it to the tire valve. Once everything is secure, turn on the compressor to fill the tire. Fill it slowly to ensure you don’t overinflate it.
