Trying not to hijack anyone's thread. I realize I don't have 35s/ 37s so don't start on me about tire size. I had a York on my last Jeep w/ tank and now have the ARB dual compressor and was wondering if it's efficient without a tank. I have a stock JK with 31s on it (don't start) and I aired down the tire to 15psi and aired it up to 25psi in 38 secs. In relation to the tire tire size does that sound relatively fast without a tank? I've read a lot the the threads here but wanted to get opinions after putting up the inflation time I experimented with this evening.
