Air compressor hard-wired. VIAR 400 high flow.
Hose has 3-way fitting with 2 locking chucks and in-line gauge. Hose is spiral wound and fits in rear cubbyhole.
Fills 4 tires without running engine using Optima YellowTop.
For beach driving its great, I use it regularly.

 

How long does it take to fill up the tires? How much does the setup cost? Looks like it doesn't take up too much space either!

 

I dont get it. The compressor is limited by its volume. You will still have to put the same volume of air in each tire... Where are you saving time?

 

Speculation, but you could hook one up and get it pumping, move to the next one and get it started, then go back to the first on and move it to the third, etc. till their all filled? Theoretically could save some time.

 

It's just easier to do 2 at a time rather than 4 individual inflates turning on-off compressor. And I use it often for beach driving.
Yes, same volume but the compressor needs to flow enough to make this effective.
It takes 4 - 5 minutes to inflate two 31"s from 16psi to 32psi.

The whole kit is the 'RV - Offroad' model by VIAR. $150.
The kit has 2 hoses with accessories and made it easy.
The compressor can be purchased by itself also. VIAR 400

 

Hi Wildmann,
That would sort of work, the tire closest to the compressor should fill a bit faster but...
The hoses are sized for doing one side at a time or just the rear, which having a locker ensures even inflation.
Also , the compressor could use a break, it's 33% duty cycle and works great for me. The 100%duty costs a few hundred bucks.
