Anyone running 325/60/20s

Looking to possibly buy some 325/60/20 BFG KO2 tires and a set of 20"x9" wheels. I'm wondering if anyone else is running the same size tire and what their experience is with performance, fuel mileage difference, and rubbing issues? They are about 1" taller and a little less then .5" wider then stock tires from what I can find. My truck is currently set to mid perch. Any time I have put a taller tire on my past trucks I have noticed a performance difference with out re-gearing and I'm wondering if the 1" more height will make any difference? Appreciate everyone's feed back. Cheers.

What offset on the wheels? That will help determine whether or not they'll rub.

Fuel wheel in either a +1 or +20 offset

Go for the +20. You may or may not get a small rub by the pinch weld. It would be minimal at best with mid perch and +20's.

Can't help you with the handling and Fuel mileage. I still have 35's.

thanks for the info
