I am ready to buy some dedicated non-winter use tires and have been leaning towards the 285/70/17 BFG A/T KO's. I have the stock 17" TRD sport rims with Bilstein 5100's on all four tires set at 2.5 in the front and a Toytec AAL for TSB in the rear. I also have 1.25 spidertrax spacers all the way around. I have a few questions before I pull the trigger:
My understanding with this setup is that I will probably have to remove the front mudflaps and do some minor to moderate trimming to eliminate most if not all rub?
I am debating between D and E load range and it looks like there isn't a big weight difference per tire but that the D range may use a softer compound for the mud and snow rating, since I won't be using these for winter, would I get longer tread life with the E?
Lastly, I have been trying to overlook this part but with gas prices the way they are, how much worse are these tires going to make my gas mileage? I currently have 265/70/17 Nokian Hakka LT Load E studded winter tires on the truck and don't find the gas mileage that bad but these tires are only 45 lbs each compared to the 55-58 lbs each that the BFGs will be.
Sorry for the long post, but I really appreciate any info that you guys can give me.
