Tow Vehicle - Front Tire Wear Issue
We tow a 2006 Jeep Liberty 4x4. I have noticed that after towing it, the Liberty's front tires rumble. So I've spun the tires on a balance machine and found only those two front tires have significa...

My experience with this is with THE REAR WHEELS of a 2007 Honda Civic and had nothing to do with towing, just an every day result of a questionable independent rear wheel design and alignment specifications. I might add, a set of wheels which were are always in "tow" mode.
On this vehicle when the rear suspension is "pushed down", the the rear wheel CAMBER changes (minus towards a plus) which causes the the REAR WHEELs to TOW IN more then a stationary TOE IN.
This vehicle was manufactured/shipped from the factory with a -1.5 Degree CAMBER CONTROL ARM. After the complaints started to come in Honda issued a TSB where the FIXED CAMBER CONTROL ARM was changed the CAMBER to a neutral -0.75 Degrees. This helped some but still caused rear tires to "scallop" for lack of a better word.
Because Honda would no longer warantee this tire wear I went to a 3rd party ADJUSTABLE REAR CAMBER CONTROL ARM. I set the rear CAMBER to 0.0 Degrees and changed the TOE to 0.0 Degrees. So now we have 0.0 Degrees of TOE UNTIL we sit in the car then our weight gives us some TOE IN and having done this many many miles and years ago it seems to have worked.
As far as the front wheels of a Jeep are concerned, I would clamp a laser level to a front wheel to see what the front TOE does when the front suspension is compressed. If you see a change in TOE then that could be a starting point to open a discussion.
