Choosing new tires...

So I've currently got 32x11.5in BFG MTs on my XJ, and recently regeared to 4.56s. I want to step up to 33s but am having trouble deciding between BFG ATs and BFG KM2s, and have a few questions...

Would the ATs give me a little better mpg than the KM2s?

Would there be a noticeable difference in road noise between the ATs and KM2s?

Any advice would be much appreciated. Also, would 33x10.5s give me better mpg than 33x12.5s? (I'm not super concerned with gas mileage... I mean, it is a Jeep... but a few extra mpgs never hurt anyone)

The km2s will be a little louder becuase of the more aggresive tread... they are still pretty quiet considering what they are. and becuase of the tread it will lower mpgs but not by much at all.. they will definitly make up for it off road tho

10.5s should give you a BIT better mpg than 12.5 (less friction better mpg) but I run the 10.5s right now & many on this site getting what I do for mpg with their 12.5s so doubt the diff is much. ATs bettter on road not nearly as good offroad so that is a personal question depending on what you will use it for, once again less friction so will be a bit quieter (think the new KM2s should be better than your old KMs) & a bit better on mpg.

I am currently waiting on my new Mickey MTZs as want to use the Jeep more offroad & wanted a more agressive look (MTZs are suppose to have good road manners & fairly quiet for a MT) while still being good onroad. It's all give & take like everything else in life.

X's two on the MTZ's. I was shocked at how quiet they are onroad. Have'nt had too much time offroad, but the are very good in the good ole Florida sand.
