Which storage orientation is recommended for tires whenever possible?

• A. Horizontally
• B. Vertically
• C. Diagonally
• D. Any orientation

Answer: (B)

Storing tires upright minimizes the amount of surface in contact with the support, which helps maintain the tire’s round shape and prevents permanent deformations. When tires are laid flat or at an angle, gravity pushes on a larger patch of tread and sidewall for a long period, increasing the chance of flat spots forming. Standing them on edge while supported keeps the weight distributed around the circumference and reduces the risk of distortion, making this the preferred orientation whenever feasible. If vertical storage isn’t possible, other orientations can be used temporarily, but vertical is the best choice.
