Just thought the jeep culture also meant respecting fellow jeepers on and off the trail guess i was wrong not coming back to this forum have a great day dont want this wayalife
I personally run 50" on an "X" model. All you need is 4 Teraflex chromoly valve stems, you can get the 5th for your spare free if you also purchase the TeraFlex HD Hinged Tire Carrier.
40's would be fine on your 30 front axle you just need to reduce some weight get rid of your front brake rotors and 4 of the 5 lugs theses things just add extra weight and are not needed.
