Tire Decision
I looked at the tire. As good of a deal as it is, the tire is too darned short for me. I took the 275.60x17 and stood it next to the factory 265.70.17 and the difference in height was pretty significant. This is a heck of a buy, but i don't want tires that can't fill the well, nor do i want to sacrifice vehicle ht.

He mentioned that they were for his 2WD Expy. The stock tire size for a 2WD Expy that has the optional 17" wheel/tire package is 275/60-17. Ford went with the lower profile, wider tread, street all-season radial spec for 2WD and the taller / narrower more aggresive tires for the 4WD Expy. . . he therefor shouldn't have any tire diameter/revs per mile related speedo error.
