Tire Inflator / Repair

A portable tire inflator tops off a slow-leaker in your driveway and reseats a plug repair on the side of the road — no gas-station compressor required. Modern units run off a 12V outlet or a built-in lithium battery and read pressure to within a pound, which beats the stick gauge in your glovebox. Keep one in the trunk if you drive on aging tires, tow a trailer, or take the car somewhere remote. Pair with a tire repair plug kit for nail-in-the-tread emergencies.
