Well I finally pulled the trigger and ended up getting the BFG KO2 for the GMT-900 2012 GMC Sierra. I opted for the 285/70R17 since I have the 2" lift up front. ended up getting them for $229 with a $50 rebate best price I could find. I opted to start at 45PSI up front and 42PSI in the rear. I noticed after going from my SUV Bridgestone Dueler tires that at 40PSI these seemed to be a little sluggish in response at that pressure.
Anyway here are the pictures.
I took it to the gym, I have to say I am loving the remote start here in Bakersfield (it was 93 when I went). Then I waited for dusk and gave it a good hand wash (about and hour). Then I started making an under seat storage container for it that I will finish up tomorrow.
