Finally had the chance to drive to Boulder and get the 275/65r18 Goodyear Duratrac tires balanced and mounted early this morning. It was tough even sourcing these tires and finding anywhere with stock.
I got a good price & service from Discount Tires in Boulder. Mounting time took about an hour, and the service techs knew what they were doing.
Subjective review of tires is great so far, good in snow and the wet stuff as I found out this morning. I didn't notice that much more humming of the tires than I did with the stock Michelin tires. It appears I probably dropped about 2 MPG for my gas mileage so far in testing.
Here are a few teaser shots of the new tires (want Mopar Off Road wheels so still waiting for those).
