One info. To correct, you can't drive while deflation because tire pressure will change depends on valve location which will lead to not accurate deflation.
Still they are good deflators

there wont be a difference just think of it when you are checking the tire pressure at the gas station, the valves are in different locations yet the pressure could be set, also when deflating while driving the tire is always touching the road surface so the pressure is always the same. another thing if you have one of those tire pressure monitors u might get my point, or get into one of those infinities FX's and check the realtime tire presure system on them, its always constant even while driving.

this is my opinion

In gas station valves in different places but tire is not moving!!! Remmber sand serfce is not constant.
Anyway I have a dash monitor system, we can try it if its working I will get one set
