If you are an avid off-roader or simply a car enthusiast, you might have come across the term “35 inch tires”. These tires are known for their superior performance and enhanced traction on rough terrains. However, if you reside in a country where the metric system is used, you might find it challenging to understand the measurements in inches. In this article, we will guide you through the process of converting 35 inch tires to metric, ensuring that you can make informed decisions about your off-road adventures.

The Basics: Understanding Tire Measurements

Before we delve into the conversion process, it is crucial to have a basic understanding of tire measurements. Tires are typically measured in three key dimensions: width, aspect ratio, and rim diameter. The width represents the width of the tire in millimeters, the aspect ratio indicates the ratio of the tire’s height to its width, and the rim diameter specifies the diameter of the wheel the tire is designed to fit.

Converting Inches to Millimeters

The first step in converting 35 inch tires to metric is converting the inch measurements to millimeters. To convert inches to millimeters, you can use the following formula:

Millimeters = Inches x 25.4

Applying this formula to our 35 inch tires, we get:

Millimeters = 35 x 25.4 = 889 mm

Calculating the Width

Now that we have converted the inch measurements to millimeters, we can determine the width of the tire. In the case of 35 inch tires, the width is typically expressed in inches. To convert the width to millimeters, we multiply the inch measurement by 25.4. Let’s calculate the width:

Width = 35 inches x 25.4 = 889 mm

Determining the Aspect Ratio

The aspect ratio is a crucial factor in tire measurements, as it determines the tire’s height relative to its width. To calculate the aspect ratio, we divide the height of the tire by its width and multiply the result by 100. In the case of 35 inch tires, the aspect ratio is usually provided as a percentage. Let’s calculate the aspect ratio:

Aspect Ratio = (Height / Width) x 100

Since the aspect ratio is not provided directly, we need to refer to the tire manufacturer’s specifications or measure the tire ourselves to obtain accurate results.

Tire Size Conversion Charts

If you prefer a simpler and more convenient method for converting 35 inch tires to metric, you can refer to tire size conversion charts. These charts provide a comprehensive list of tire sizes, including the corresponding metric measurements. By locating the 35 inch tire size on the chart, you can quickly determine its metric equivalent without performing any calculations.


Converting 35 inch tires to metric might seem like a complex process initially, but with the right knowledge and tools, it becomes much more manageable. By understanding the basics of tire measurements and utilizing conversion formulas or charts, you can confidently navigate the world of off-road tires and make informed decisions about the best fit for your vehicle. So, go ahead and explore the great outdoors with the perfect set of tires that suit your needs!
