Being he has a 2014 Chevy, and a listed p on current tire size, im gonna bet that he has the stockers.
I have a 35lb more per tire and wheel on my current 34.5" mud tires compared to the all terrain 30.5" stock size (both 10 ply) and i notice a mpg and brake difference.
....but like OC said there will be less resistance and probably not alot of weight difference on OP's size difference, so probably a wash.
