tire size/stock ride height
i have a 99 PSD 4X4
running 265/75/16 and they look like bike tires. The one owner used the truck for towing and has a 4 in block rear and 5 leaf springs on the front. I want to put on 305-315/75/16 on it but trying to save on an expensive lift kit. just wondering if there is enough clearance with the present set up.
