Abstract: What is provided is a portable air hose device for transferring air between tires of a vehicle. It has a locking end for attaching to a tire into which air is to be added, a coiled hose, and an end for attaching to the valve of another tire, from which air is to be transferred away. The attaching end may be locking or non-locking. The hose may be a coiled hose or in some examples it may be a straight air hose. The volume of air transferred may be regulated by the user, and some examples may have a pressure gauge to measure air flow transfer. A user may attach the device between two tires to transfer air tire to tire. The device may be used to add air to flat tires and/or low tires, and/or to equalize air pressure in the tires of a vehicle.
