Understanding Tire Codes
If you’re wondering what size tire is 275-65r18, let’s break down the tire code to understand it better. The first number, 275, represents the section width of the tire in millimeters. The second number, 65, is the aspect ratio, which is the proportion of the sidewall height to the section width.
It’s represented as a percentage, so in this case, the sidewall height is 65% of the section width. Finally, the letter “R” indicates the tire’s construction type, which is radial. The last number, 18, is the wheel diameter in inches that the tire should be used with.
So, to sum it up, a 275-65r18 tire is a radial tire with a section width (sidewall to sidewall) of 275 millimeters, a sidewall height 65% of the section width and meant to be used with an 18-inch wheel. Understanding tire codes can help you choose the right tire for your vehicles easily.
