    I don't have a lift on the truck. Running stock wheels and had the front keys turned to level the truck. What would be the largest tire I could put on this without having to do a lot of modifications?

    I have cooper discoverer ATR's on my 07 classic 1500. They are 315/70R17. They fit with just a bit of cranking to level out the front. IMAG0144.jpg FIRMNESS.jpg

    They barely rub when the wheel is turned full left (slightly rubs on torsion bar) and I also did some minor bumper notching


    The circle is where I had to cut the bumper back
