I checked in the Michelin spec book and the only
size that looks close would be 245/70/17E. It
measures 9.5" wide by 30.6" tall and is the correct load rating for a 3/4 ton. Most of the 17" tires listed are for suvs and sport truck, not well suited for useage on a 3/4 ton. There
is also a 265/70/17 listed,it may not clear the
fender/drag link as it is taller and wider by 1".
