I bought a lifted truck recently and I'm told there's a 3"suspension with a 1" body for roughly 4" total of lift. I measured the front center of hub to fender and I'm at 22 7/8". What's a stock third gen measure from center of hub to bottom of fender? I'm starting to think the previous owner was mistaken. I just ordered 315s to put on because I'm told you can run them with a 4" lift and some manipulation of the pinch welds. Am I screwed here? Tires have to go on as these current ones are dry rotted something fierce (BFG K0). Any and all input is appreciated as I'm new to third gens and they're slightly different from my 5th gen.
