The low-speed (up to 4 miles per hour) yawed-rolling characteristics of two 40 X 12, 14-ply-rating, type VII aircraft tires under straight-yawed rolling were determined over a range of inflation pressures and yaw angles for two vertical loadings. One load was approximately equal to the rated vertical load and the other load was approximately equal to twice the rated vertical load for these tires. Static tests were also performed to determine the vertical, lateral, torsional, and fore-and-aft elastic characteristics of the tires.
