Raceline wheels, new tires need help...

Hi, I have a 2010 DBL cab off road with OME 886 springs without top spacer. ARB bumper, warn winch, and Dakar leafs. I have Raceline renegade 6 wheels with 4.5"BS. My question is on the tire size. (265-75-16) (285-75-16)
(255-85-16)
1. 265-75-16's no trimming
2. 285-75-16 remove mud flaps and possibly the cab mount chop
3. 255-85-16's which are the largest of the 3 tires at 33.7" tall.
I really like the looks of the 285's but don't want to sacrifice the gas for the larger tires. I like the idea of the 265's (a little cheaper) and not having to do anything to flaps and cab mount. I have yet to see anyone running a ARB bumper and OME 886 springs. I called ARB and they told me that they could not recommend any tire size for their lift kits. He talked about some liability? If anyone has an ARB bumper and 886 springs can you let me know what tire size you are running? My wife drives the truck 3 times a week to work and is only 5'-0" tall and even with the 886 springs she had a hard time getting in. Thanks and sorry for rambling..

 

You wont lose much mpg. when I had my 2006 TRD, i installed 285/70/17's and barely noticed any difference.
