I got a brand new 4" rc lift in my jeep and im currently running 32's which look nice on my yj, but they are my stepbrothers and we are trading back soon.. but anyway.. i have the money to purchase new tires finally and im just trying to get some opinions on 31x10.5s and 33x12.5s. do the 12.5s fit on stock rims? will 31s look to small? even with an aggresive tread? and furthermore my jeep is a 2.5L, will there be a noticeable difference in the jeeps power between the two size tires? (not like i have incredible power to begin with.. ) advice would be awesome! and pics are even better! thanks jeepers!
