Air Inflators For Tires

Air inflators for tires help you tackle routine tire pressure checks and top-offs before a drive into town, a trip with the trailer or a busy day around the farm. A portable tire inflator can be handy for adding air to car, pickup truck, lawn mower and utility trailer tires, as long as its pressure range, airflow and power requirements fit the job. As you compare tire inflators, look beyond maximum PSI and consider the size of the tires you’ll be filling. Larger tires need more air, so airflow and the inflator’s duty cycle—the length of time it can run before needing a cooling break—matter just as much as pressure capacity. Cordless tire inflators offer flexibility away from an outlet, while models powered by a vehicle’s accessory socket or a household outlet need a suitable power source within reach. Check hose length and cord reach, too, especially if you’ll be working around a long truck or trailer. Choosing an air inflator for tires also means thinking about how you’ll check pressure and store your gear between jobs. Features to look for include an easy-to-read pressure gauge, a secure valve connection and an automatic shutoff that stops inflation at a selected pressure. For cars and trucks, check tire pressure with the tires cold and follow the recommended PSI on the vehicle’s tire information placard or in the owner’s manual, rather than treating the maximum pressure listed on the tire sidewall as your target. For trailers and lawn equipment, follow the applicable manufacturer’s tire pressure guidance. Keeping tires properly inflated supports handling, helps limit uneven tread wear and gets your equipment ready for the work ahead. Keep a separate tire pressure gauge on hand to verify readings, and remember that a tire air inflator adds air but does not fix a puncture, damaged valve or other leak. If a tire keeps losing pressure, have the cause checked before putting it back to work.
