i have a little alligator style air compressor made by smittybuilt take about 30-40 minutes to air my 35/12.50 inch tires from 8psi to 32. has anyone delt with a airtank that they maybe fill up at home to 130 psi and use that to fill all 4 tires up to say 25 psi and the compressor to fill the rest of the way. my 33 gal garage compressor filled to 150 max will fill all my tires from 8-35psi in about 7 minutes with out needing to be turned on, naturally im not gonna haul my big ass compressor around with me wheelin, just curious to get someons opinion wether a 10gal tank or 20 gal tank would be worth it to mount under the bed or just throw in the bed with out taking up to much room. i dont want t0 go buy one find out i could use a little bigger one for what i need. i dont want to tap into my a/c compressor or buy a expensive 400 dollar compressor

^^ what he said.

 

You run your 35's at 32 psi?
On my 4runner i run mine at 25.... and mine is daily driven.

 

You can run some numbers and see what a given tank and pressure will do for you:

you can get all the parts together and make a co2 system cheaper that getting the powertank and ultimate air systems

 

^x2 this is what i did .. check craigslist and ebay .. i dont remeber what i paid for my 20lb aluminum tank but it wasnt that bad .i have seen them on craigs for $50 used with good dates,this is only the tank . the only problem i have is with my cheap fixed psi regulator .. after 3 tires it starts to freeze up so i have to wait until it defrosts .. i also use it to fill my air mattress when camping and have used it to power some air tools .. it also lasts for while , i was suprised how long the co2 lasted actually..
