Update - New Tires Installed
I no longer rub after installing the new Sumitomo HTR Z III tires (size are in post #1.) My next test will be to drive around with a full load, and passengers. This afternoon I drove around town on some bumpy uneven roads - could not get the rears to rub...at all. My hunch is it will not rub will passengers.
In addition the tires also look much better. The rear tires lost that "fat" beefy look. These tires are super quiet and handle well. Overall I'm very pleased.
Pics coming soon.
