Back to the WM discussion: truckdog makes it very clear that F3 stock (rear) 17" , 2 piece wheels are all rh5's and therefore widow-makers. My F3 has those on the rear and before becoming aware of this, about 4years ago I had new tires installed on them by a local tire place here and they made no mention of a potential problem or any concerns. This is a company with 18 shops in the northwest. Is the potential problem with the design or with the wheels when they get old ? Are you suggesting that you would remove them even if they were in good condition as mine are? Btw my truck probably only gets driven a few hundred miles per year. Just trying to figure out just how much of a concern this is. Thanks, Brian
