Technical Reference
Tire Dimensions & Technical Specifications
Overall Diameter
Distance across unloaded tire from tread surface to opposite tread surface.
Section Width
Cross-section of unloaded tire through carcass only, excluding channels or protrusions.
Tread Depth
Distance from tread surface to base of grooves at a designated measuring point.
Static Load Radius
Distance from axle center to floor under maximum dual load and inflation as shown on sidewall.
Revs Per Mile
Number of tire revolutions per mile, measured at 55 mph under maximum dual load and inflation.

All dimensions measured following a 24-hour inflation period. Aspect Ratio = Section Height / Section Width.
Technical Reference
Speed Symbols & Dual Fitment Guidelines
Speed Symbol Reference
Dual Matching Limits
Radial tires must be matched within ¼" diameter and ¼" circumference. Never mix diagonal and radial tires in dual applications. Never use different rim widths in dual applications.

Mismatched duals cause rapid, irregular wear and risk sudden air loss. Each ½" OD difference = 1.56" circumference difference.
