Tire Size 35×10.5r15 to Metric

What does 35×10.5r15 mean, and why should you care? Today, we’ll unlock the mystery of these alphanumeric codes and illustrate how you can convert this seemingly cryptic jargon into something you can use – even if you aren’t a car enthusiast.

Dimension Breakdown
A tire size like 35×10.5r15 is not as complex as it first appears. Each part has a specific meaning:

  • 35: The overall diameter of the tire in inches when fully inflated and not under load.
  • 10.5: The tire width in inches. This is the distance from one sidewall to the other.
  • R: This stands for Radial, indicating the tire construction type. Most tires today are Radial.
  • 15: The wheel diameter in inches. This is the wheel size that the tire is designed to fit.

35×10.5r15 in inches

Tire Diameter35.0″
Tire Section Width10.5″
Rim Width Range15″
Sidewall Height10.0″

Conversion Process
Let’s dive into the process of converting this tire size from inches to millimeters.

  • Overall Diameter: The overall diameter is 35 inches. Since 1 inch equals 25.4 millimeters, we multiply 35 by 25.4 to get 889 mm.
  • Tire Width: The width of the tire is 10.5 inches. Multiplying 10.5 by 25.4 gives us a tire width of 266.7 mm.
  • Wheel Diameter: The wheel diameter is 15 inches. Multiplying 15 by 25.4, we get a wheel diameter of 381 mm.

Sidewall Height
The sidewall height can be calculated using the formula:

  • Sidewall Height in inches = (Overall Diameter – Wheel Diameter) / 2

So, the Sidewall Height = (35 – 15) / 2 = 10 inches. Converting to millimeters, we get 254 mm.

Aspect Ratio
The aspect ratio is the ratio of the Sidewall Height to the Tire Width multiplied by 100%.

  • Aspect Ratio = (Sidewall Height / Tire Width) * 100%

Hence, the Aspect Ratio = (10 / 10.5) * 100% = 95.24%.

Finding a Close Metric Equivalent
Finding a close metric equivalent involves identifying a tire that closely matches the key characteristics of the original. In our case, a metric size approximating 35×10.5r15 might be something like 265/95r15. This indicates a width of 265mm, an aspect ratio of 95%, and a rim diameter of 15 inches.

Practical Applications
The 35×10.5r15 tire size is commonly found on off-road vehicles, like trucks and SUVs, due to their larger dimensions and ability to withstand tough terrains. 

Their wider width provides more stability, while the larger diameter allows for greater ground clearance. For example, vehicles such as the Jeep Wrangler or Ford F-150 often use tires of this size for off-roading adventures.

What Is Equivalent To A 35×10.5r15?

The tire size specified as 35×10.5r15 can be approximately converted to the metric system as 267/95r15. However, it is important to mention that this particular size is seldom found in commercial stores.

A metric dimension that is more commonly encountered and serves as the closest equivalent is 265/95r15. This size closely resembles the characteristics of a 35×10.5r15 tire and is readily accessible for consumers to purchase.

How Tall Are 35×10.5r15 Tire Size?

The first number in tire dimensions (35×10.5R15, in this case) generally indicates the tire’s diameter in inches when fully inflated, which is also the height from the ground to the top of the tire. So, a 35×10.5R15 tire is approximately 35 inches tall.

How Wide Is A 35×10.5r15 Tire?

The second number in the tire size (35×10.5R15) is the width of the tire. This width is usually given in inches. Thus, a 35×10.5R15 tire is approximately 10.5 inches wide.

What Size Rim Fits 35×10.5r15?

The last number in the tire size (35×10.5R15) typically represents the diameter of the wheel (or rim) that the tire is designed to fit. This diameter is provided in inches. So, a 35×10.5R15 tire is designed to fit a 15-inch diameter rim.

Understanding and converting tire sizes like 35×10.5r15 from the imperial to the metric system can seem daunting, but once you know the breakdown and conversion process, it’s as simple as riding a bike.

This knowledge allows you to find a close metric equivalent, which can be essential when purchasing new tires in different regions.

Whether you are an off-roading enthusiast or just want to make sense of your vehicle’s tire size, this understanding can be quite useful. So, don’t let it intimidate you the next time you see a tire size. Instead, let it open up a new world of knowledge.
