|---|---|
| 275/70R22.5 | 275 is the width in millimeters, 70 is the aspect ratio, R means radial, 22.5 is the rim diameter in inches |
Width
The width of the tire is the first number in the size. It is measured in millimeters. For example, in 275/70R22.5, the width is 275 mm. A wider tire can offer better grip but can also affect fuel efficiency.
Aspect Ratio
The aspect ratio is the second number in the tire size. It is a percentage. It shows the height of the tire’s sidewall compared to its width. In 275/70R22.5, the aspect ratio is 70%. This means the sidewall height is 70% of the tire’s width. A higher aspect ratio means a taller sidewall.
Construction Type
The letter after the aspect ratio tells you the construction type. Most heavy-duty vehicles use radial tires, shown by the letter “R”. Radial tires are better for fuel efficiency and durability.
Rim Diameter
The last number in the tire size is the rim diameter. It is measured in inches. For example, in 275/70R22.5, the rim diameter is 22.5 inches. The tire must fit the rim size of your vehicle.
