Default MPG Expectations on 3"RC 31x10.5 BF

Hello,

I Put a 3" RC on my 2WD (I know but I like how it looks) and I'm getting ready to put some BF T/A 31/10.5 and I was wondering what I should be looking at as far as my MPG's for those that have that set up. I know most of you have 4X4 but I was hoping I could get some info on those of you that are on 2WD.

Thanks in Advance

Okay here is a follow up....

Got the tires on friday and I noticed much nicer softer ride but definitively sucking up some ponies. 31x10.5 BF AT.

I also noticed that the jeep is running a little warmer with them on use to run below 210 now it runs right at 210, and lost some take off speed. I use to be able to haul *** now not so much.

Went to the beach and sunk almost imediately in the sand... now looking for the 4x4 conversion.. found a guy in Dallas that will do it for 1000 with parts.

For those wondering my cooling I have a 3 core radiator, tranny cooler and upgraded to the late 90's aux e-fan

iTS A jEEP. I shave my head, wear ligthweight clothing, don't carry change in my pockets, no under wear, no socks, flip flops, no belt. I only carry a drivers license and a debit card. Empty by bladder before I drive my jeeps.

Nothing seems to allow me to get 30 MPG. So I just drive it like I stole it, enjoy it, and deal with the 19-21 MPG.

No lift,(yet) 30x9.50 15 inch tires and a 5 speed, 4.0, bored out TB, 703 injectors, 8mm wires, High preformance Coil, modified air box K&N filter, Kellys #4 wire replacement kit. Cat back next week
