The orange/red dot on the side wall (see earlier photo) is a low run-out spot on the tire marked by the manufacture.This is to be lined up with the high run-out spot on the rim,noted by a shot welded to the outer rim lip.This was incorporated into production at Norwood,Flint,and Willow Run when the tire was mounted.This is directly from a Dealer service info Bulletin 68-I-5 dated Dec.6 1967.There goal was "...to improve vehicle ride by minimizing tire and wheel run-out variations."
