The BEST tire Deflation/Inflation system available.

- Air down 4 Tires at Once
- Equalize all 4 Tires
- Air Up all 4 Tires at Once
- Compatable with most Automatic Tire Deflators

All from INSIDE your vehicle!

When you get to the trailhead, connect the four air chucks to each of your four tires, get back in your rig and start deflating in the comfort of your rig while watching others stand in the rain, snow, or cold. Open the ball valve and all four tires begin deflating, close the ball valve and read the pressure on the gauge. See How it works here. Four 35" tires can be deflated from 32 psi to 15 psi in about 5-6 min all from inside the cab. Stay warm and dry! Once the pressure you want is reached, disconnect the four air chucks and go! And because they are all connected together, all four tires will be at the exact same pressure. Ideal for Lockers!

At any time you may connect the system and equalize the pressure in all the tires. (Useful to transfer air from your spare tire, or from one rig to another if no air source is available.)

When you get back to the road, connect the four air chucks to each of your tires and connect an air compressor, OBA, or CO2 and reinflate all four tires at the same time. The tire stem on your tire is the biggest restriction to filling your tires, so by filling all four at once, you can refill all four tires in about the same time it takes to reinflate just one. For example, four 35" tires can be inflated from 15 psi to 32 psi in 1:30 using a regular home air compressor. From inside your rig, and out of the weather. And because they are all connected together, all four tires will be at the exact same pressure. Ideal for Lockers!
