I'll give an enthusiastic 2nd to those 700R15LT Yokohamas, Russ - they look good, raised my 58 about 2" [gonna take a while to learn to quit trippin on the door step!] - made it like power steering compared to the old passenger radials - the narrow tread reduces rolling resistance too - trucks were meant to have truck tires!! I got the ribs on the front, lugs on back [it is a work truck]
