Tire width of 265/65R18
When we say a tire has a width of 265, we’re not talking about the width of a freshly baked baguette or the wingspan of an eagle. We’re talking millimeters here, folks! A 265/65R18 tire has a section width of 265 millimeters, equivalent to approximately 10.43 inches. So, if you’ve ever wondered how wide these tires are, just imagine about ten and a half baseballs lined up side by side. That’s a wide tire!
Tire height of 265/65R18
Tire height, also known as tire diameter, is calculated by doubling the sidewall height and adding the diameter of the wheel. For a 265/65R18 tire, the diameter is roughly 31.56 inches. If tires could play basketball, they’d have no trouble reaching the hoop! Remember, this is just an approximation and can vary slightly based on the specific tire model and brand.
Sidewall height of 265/65R18
Sidewall height, often overlooked, is the unsung hero of the tire world. It’s what provides your ride with cushioning and affects your vehicle’s handling. The sidewall height of a 265/65R18 tire, which represents 65% of the tire’s width (as explained earlier), is about 6.78 inches. In simpler terms, it’s about the length of a dollar bill!
Rim diameter for 265/65R18
The “18” in 265/65R18 refers to the wheel or rim diameter, which is 18 inches.
