I bought them from 4wheelparts. One of the boxes was missing the hardware kit so they overnighted a whole new one from California. I can't say how much that amazed me. Wonderful customer service. I got them on yesterday and I do have some vibration in 2wd just driving down the road. Mainly when going around a curve at speed. However my tires are cupped and out of balance and it needs aligned. I will be taking care of all that in the next week or two and will post up if it took care of the vibration. My wheels are 17x8 +10 offset. 315 70 17 should fit. I will probably go back with bfg at ko. Been looking at the trail grapplers but I want something thats going to last awhile and the at ko's seem to run forever. I will post up some pics of the new tires when I get them on.
