Does deflating your tires down to 3-10psi put anymore significant stress on your drivetrain(axels,u-joints,drive shafts etc.) than not airing down at all. I figure the rolling diameter change may effect torque throughout the driveline and on its components.... Although i seem to brake more parts when i'm spinning the tires then when i'm not...hence airing down for traction.

It wouldnt be very noticeable, but like you said your airing down for my traction.. So with traction you will add stress to shit.

Well, there's no question your "rolling resistance" increases, and the tires grab better, so in theory, this would translate to a greater chance of breakage. The alternative, not airing down, will leave your tires spinning, and not grabbing, and then a LOT more shock to the system, when they finally do grab, or just not getting over the obstacle you're trying to cross.

In snow, it makes a huge difference, to air down - you tend to float on the snow more, rather than sinking in, and staying there.

i think with my driving style the better traction/less horsepower(wheelspin) technique seems to be the answer...in the snow i've noticed excellent traction deflating and i don't believe breakage is as much as an issue in the snow.
