Questions, answered
What pressure do my bike tires need?
Road bikes: 80 to 120 PSI. Gravel: 35 to 60 PSI. Mountain bikes: 25 to 35 PSI. Hybrids and commuters: 40 to 65 PSI. The sidewall lists a max, but the right number depends on rider weight and tire width, so start mid-range and adjust by feel.
Do I need a presta adapter?
Most portable inflators ship with both schrader and presta fittings or a dual-head chuck. Confirm the box contents before you buy; a missing two-dollar adapter is the most common reason a new inflator cannot touch a road bike.
Will a tire inflator damage a bike tube?
Not if you use the preset shutoff. The risk with compressors is overshooting a low-volume tire in seconds. Set the target pressure on the digital gauge, let auto-shutoff do its job, and you are safe.
