I love these and always take them off while wheeling and put the regular caps back on. Also, you will want to set your deflators before you go and a good way to do that is to air your spare down to the desired PSI and then set each of them to that PSI. It's pretty easy to set and even easier to use when you are airing down on the trail. Those are a good buy.

I regularly air mine down to 15 psi and haven't broken any beads yet with the stock Rubi tires\rims. I know alot of other guys that run down to 8 psi, but 15 seems to have treated me pretty well.

I have had my stock Rubi BFG's down to 5 psi in the snow..because there is not much sidewall to flex on the BFG's 5 psi worked great and I really needed last time in the snow...rock crawling I agree that 12 to 15 is just fine

not to mention the deflators are a bit pricey.

sucky sucky
and my Staun deflators are supposed to be at 18 psi out of the box, but they were closer to 15, but we had no problems.

Cheapo compressor from Costco works just great. Stock Rubicon tires air from 15 to 37 in 3 minutes each. Really a great little pump for 40 something dollars.

I picked up the Smittybuilt Deflators at 4WheelParts for $30 and they are identical to the Stauns that are $60. I also have the Viair 400p compressor that works fine to air up my 35's in about 2 1/2 minutes each from 15psi to 30psi.

Or you can just make your own for about $30 and make sure the tires are the exact same pressure.

VBS4- I do intend on making this setup for my Jeep. I read the writeup some time ago and loved the idea. Thanks for reminding me of another project.
Thanks for everyone posting. I can explain the reasoning of airing down much better than before. Sometimes it's not learning something really new but being better able to help someone understand all the reasons why something works better.
