I have a 2004 new body style Lariat SCREW. I currently have the 18in stock wheels and cannot install chains due to the tight clearances to the upper A-arms (front) and shocks (rear), without damage. Due to tire prices I am planning to buy new 17in wheels and need to know what wheel spacing to get to clear a set of chains. It looks like another inch will suffice. Has anyone had this issue or insight?
