Take the guesswork out of maintaining proper tire air pressure with the Cali Raised Offroad on board Air Compressor Kit. It can be used to reinflate tires after deflating them for off-road adventures or to top off tires when the Tire Pressure Monitor (TPM) indicates low tire pressure. This integrated onboard compressor can also be used to inflate air mattresses, soccer balls, footballs, basketballs, bicycle tires and pool floats.
