255/85 mud terrain vs 285/75 AT

Which of two tires options would you say offers the least rolling resistance(power drain) on a truck that’s been geared to 4.88?

255/85 BFG mud terrain @ 54lbs & 33.3”x10”
or
285/75 AT @ 52lbs & 32.8x11.2”

 

What PSI and load rating are you accounting for in your information above?

 

I would say 255 purely from the width stand point. Could do 255 st maxx which is a mix between AT and MT and get the best of both worlds.

 

For 255 it’d have to be load range e. No other options there. 285/75 it’d be load range c.

The ST Maxx is 59lbs and I’m weight is a big factor for me on tire choice. It’s a great tire though.

 

Regular cooper S/T come in a C load for 255/85.
