hey all, I'm really itching to change out the stock wheels on the truck ... I picked out a rear size thats very close to the stock size, see below: but I'm consistently coming accross threads that ask people to refrain from using staggered fitments - my question is can I use the 305/45-20 in the back like the X5 has wider ones in rear ? Or in worst case use all four 305s ? How would the ride be impacted ?
