Does anyone know how high of a lift I have to put on my x in order to fit 305/70/18 tires? Its fully stock right now and I found a great deal on tires and need shocks too, so why not throw on some great tires and a little of a lift right hahah....Or if you know where I can go to find the answer to this...thank you all

 

6inch suspension will do the trick. I have a 350 with a 6 inch and 35s. The 305 u have is equivalent to a 34.5 x 12
