Understanding Tire Specifications
What the Numbers Mean
Tire sizes like 295/75R22.5 and 11R22.5 are represented with specific coding that conveys vital information about the tire’s dimensions and construction.
-
295/75R22.5: The first number, 295, indicates the width of the tire in millimeters. The second number, 75, represents the aspect ratio, which is the height of the tire’s sidewall expressed as a percentage of the width. The “R” denotes radial construction, and 22.5 indicates the diameter of the rim in inches.
-
11R22.5: The “11” refers to the width of the tire in inches, while “R” signifies radial construction, and “22.5” indicates the rim diameter. The lack of an aspect ratio means the sidewall height is relatively taller compared to the width, affecting vehicle performance and handling.
Metric vs. Imperial Measurements
One of the primary differences between these two tire sizes is their measurement systems. The 295/75R22.5 uses metric measurements, while the 11R22.5 uses imperial. This distinction is critical when considering compatibility for your vehicle, as it affects load capacities, ride quality, and overall performance.
