Viair 40047 400P-RV Automatic Portable Compressor Kit
It is too difficult to find a service station that can provide convenient compressed air with long enough hoses and high enough pressure. Its best to fill the tires when they are cold, not after driving around trying to find a service station. Correct tire pressure is essential and potentially life saving to help prevent a catastrophic tire blowout. The best way to know what the correct tire pressure should be is to have each axle weighted. Otherwise, the manufacture gives recommendations for cold tire pressure and axle weights as well as each tire manufacturer gives tire pressures for a given weight.
The easiest solution is to have a portable air compressor that can be used on the spot. It connects to the Jeeps battery and has plenty of power to easily inflate any RV tire. It is easy to set up. The hoses are long enough to reach all the tires. The only thing missing is a valve stem tightener, which we have needed. Even though the large pressure dial is easy to read, we still purchased a digital tire pressure gauge to fine tune the pressure.
This VIAIR is made for RV’s but can be used for any vehicle. It has automatic shut off, primary & extension hoses, quick connect coupling, 160 psi gauge, heavy duty battery clamps, and a heavy duty carrying bag that does not take up much space.
