i had an '07 2 door X with the 3.73 gears and 35/12.50R17's, it was my daily driver and i loved it. it did fine for over 20k miles untill i traded it in om my 4 door rubicon. the tires did make a difference in power obviously, but had enough to drive the speed limit wherever i went, even up I-70 through the rockies. all i had was a 2.5" coil lift that i made myself here at my shop and i put the proper backspacing wheels on it.
sorry i thaught i had some pics but i dont know where they are.
