Is anybody out there familiar with the automotive engineering of multiple axle vehicles? When there are 2 non-steering axles at least one of them will be slipping in a turn, maybe both in opposite directions. Is it only a low speed tight corner thing or does it come into play on the interstate? What is the effective wheelbase of the vehicle? I'd guess the average of both axles if they were equally loaded. The whole trailer sway issue would be moot if they always went straight.
Here's one you can read about.And only a half a mill! Oops, too bad they are out of production.
To answer your question. Yes a tandem axel vehicle will scrub the tires at low speed, high speed or any speed. It will just depend on how much you are turning as to how much scrub you will get. The pivot point will be between the two axels.
