Dually rear tire question. New tires steering sloppy.

Many new tires also need a break in per say of 2-3000 miles before they start to handle correctly.

Or the tread pattern is enough difference that handling is different too. HWYs usually pull better than AT style which pull better than mud/snow tires.

As noted, sidewall stiffness can also effect handling. OR as I have had in many cases.......first set of new tires also means I needed new shocks on the rig too! may not be a tire issue!
