New wheels what size tire!

[Cableman]

Im kicking around the idea of getting some fuel contras wrapped with nitto trail grapplers.

I dont wanna lose too many mpg's so was thinking of staying stock size with 275/60/20 reg load range not an E. The 305/55/20 is only a few pounds heavier at 51lbs.

I cant make up my mind if i want the wider 305 or not! I would choose the +1 offset for either tire which would bump it out a tad more then stock. Both look good but it seems most seem to bump up to the 305 tire.

This one is on stock size so they say

If you know your differential gear ratio you can use this chart to get a guesstimation (trans ratio 1:1) on what size tire you want to use for highway, normal, or tow/performance mpg's.

3.91 and 33's, who woulda thought highway driving lol
I wanna stay at 33's just not sure if i i want 275 or 305. Id have to think more tire on the ground would effect mpgs also, but is it really much more idk!
Do 305 tires change the ride at all vs a 275?
