Staun Tire Deflators (Airdown to 15-55 PSI) Heavy Duty

The primary use for this would be for going off-road but in my case, I have a heavy duty truck and while towing I need to run 80 psi rear and 60 psi on the front. I drive the truck without towing often and reducing to 40 psi rear and 45 in the front really helps the ride quality and tire wear. These work great for this purpose! In addition, I messaged Staun with a question about my front tire pressure and Nick responded within 24 hours with exactly what I needed without any back and forth. Great product, great support!

The poor machining quality leads to inconsistent and inaccurate results. Tires have generally similar pressure, but when I tried the same bleeder on all four tires I received different results over 7 different attempts. Example pressures: 45, 43, 42, 37 This set of pressures all came from the same bleeder.

BRILLIANT!! What a difference from bending over my tires, 2 minutes for each tire. Oh my gosh. Amazing. Accurate, plenty fast.

I purchased this product because tires on new vehicles are overinflated from the factory to prevent creating a hard spot during transport, and must be aired-down before delivering to customers. I have these set at 40psi while factory tires are 50-60 psi. So far, they generally go between 39-41 psi which it well within expectations. I check every tire with the display on the instrument panel. So far I have done several hundred vehicles without a single major error. They typically deflate a 33" tire from 60psi to 40psi in about 40 seconds, which means by the time the last one is installed, the first one is ready to go. The speed is unbelievable for the accuracy I am getting. I cannot speak as to how great they are for off-roading, but I expect this to work great. I recommend getting the speed chuck adapters from Skog if you intend to use these regularly.

So far, these have done their job just fine and deflation has been pretty consistent +/- 1 psi. The small, compact size makes them great for glove box storage.
