Is a 35-inch Tire Equivalent to a 285 Tire?

[OKyle]

Not necessarily. 35 refers to the tire size, while 285 indicates the tire width. To make a proper comparison, they need to be converted to the same unit. For example, a 35-12.5-R17 tire typically has a width of approximately 317.5 mm. Below is relevant information about tire specifications: Tire Specifications; Tire specifications are commonly represented by a set of numbers, where the first number denotes the tire section width, and the latter indicates the rim diameter, both in inches. For instance, a tire labeled 285/70/17 signifies a tire with a width of 285 mm, an aspect ratio of 70, and a diameter of 17 inches. Classification by Tire Usage: Tires are categorized by usage, including types such as truck tires, passenger car tires, and mining tires. In addition to the size specifications marked on the sidewall, truck tires must also indicate the ply rating. However, it is important to note that the ply rating of truck tires does not refer to the actual number of layers but rather to the load-bearing performance of tires made with high-strength cord materials, which is equivalent to the number of cotton cord layers in traditional tire construction.
