Frequently Asked Questions
How often should I check my tire pressure?
At least once a month and before long road trips. Tires lose about 1 PSI per month naturally. Driving on underinflated tires reduces fuel efficiency by 3% and increases tire wear significantly. A portable inflator makes it easy to top off at home.
Can a portable inflator handle truck or SUV tires?
Most 12V portable inflators can handle standard car and SUV tires. For larger truck tires or off-road tires above 35 PSI, look for a heavy-duty model like the VIAIR 88P with a higher CFM rating. Check the max PSI rating before buying.
12V plug-in vs cordless inflator — which should I get?
12V plug-in inflators are cheaper and never run out of power — ideal for keeping in your car. Cordless inflators are more convenient for home use and work without the car running. If you can only buy one, a 12V plug-in for the car is the safer emergency choice.
