Tire Size 35×11.50r20 in Metric

Consider the tire size labeled as 35×11.50R20 – it can indeed seem puzzling. But what does this bewildering array of characters convey about the tire’s dimensions? Today, let’s unravel this mystery and gain a deeper understanding of what these vital figures signify.

Dimension Breakdown
The series 35×11.50r20 might seem complex at first glance, but when you dissect it, the information is quite straightforward. The first number, ’35’, represents the overall diameter of the tire in inches.

Next, ‘11.50’ is the tire width, also in inches. The letter ‘r’ denotes radial construction, the most common tire design in use today, and finally, ’20’ indicates the wheel diameter, again in inches.

35×11.50r20 in inches

Tire Diameter35.0″
Tire Section Width11.5″
Rim Width Range20″ x 8-10.5″
Sidewall Height7.5″

Overall Diameter
To convert the overall diameter from inches to millimeters, we simply multiply by 25.4 (since one inch equals 25.4 millimeters). So, a 35-inch tire is 889 millimeters in diameter.

Tire Width
The tire width follows the same process. Therefore, a tire with an 11.50-inch width measures approximately 292.1 millimeters.

Wheel Diameter
For the wheel diameter, the 20-inch wheel translates to 508 millimeters.

Sidewall Height
The sidewall height represents the distance from the wheel rim to the top of the tire. It’s not directly mentioned in the size but can be calculated. Using the formula (Overall Diameter – Wheel Diameter) / 2, the sidewall height of a 35×11.50r20 tire is (35-20) / 2 = 7.5 inches, or approximately 190.5 millimeters.

Aspect Ratio
The aspect ratio is a percentage that indicates the height of the tire’s cross-section to its width. Using the formula (Sidewall Height / Tire Width) * 100%, the aspect ratio for a 35×11.50r20 tire is (7.5/11.50) * 100% = approximately 65%.

Finding a Close Metric Equivalent
The tire size specified as 35×11.50r20 can be approximately converted to metric system notation as 292/65r20. However, it’s important to mention that this specific size is seldom found in commercial outlets. For instance, a tire size of 295/65r20 has very similar dimensions.

Practical Applications
The 35×11.50r20 tire size is prevalent among light trucks and SUVs that require larger and wider tires for off-roading or heavy-duty applications.

For example, you might find this tire size on a Ford F-150 Raptor, renowned for its off-road prowess, or a Ram 1500, which needs such robust tires for towing and hauling.

What Is Equivalent To A 35×11.50r20?

The tire size expressed as 35×11.50R20 could be approximately translated into the metric system as 292/65r20, although it’s important to mention that this particular size is seldom encountered in retail stores.

A metric dimension more commonly observed, and the closest analog, is 295/65r20. This size closely reflects the characteristics of a 35×11.50R20 tire, offering a wider availability for customers seeking to purchase.

How Tall Are 35×11.50r20 Tire Size?

The first number in the tire dimensions typically represents the height of a tire. In the case of a 35×11.50r20 tire, the height (or diameter) when fully inflated is approximately 35 inches.

How Wide Is A 35×11.50r20 Tire?

The second number in the tire dimensions usually represents the width. So, for a 35×11.50r20 tire, the width would be approximately 11.50 inches.

What Size Rim Fits 35×11.50r20?

The final number in the tire dimensions typically represents the diameter of the rim that the tire is designed to fit. Thus, a 35×11.50R20 tire is designed to fit on a rim with a diameter of 20 inches.

The world of tire sizes isn’t as complicated as it might initially seem. Understanding the meaning behind the numbers and letters, such as with the 35×11.50r20 tire, not only helps you make informed decisions when purchasing new tires but also enhances your knowledge about your vehicle’s capabilities.

The next time you spot these numbers, you’ll know exactly what they’re telling you, and how they contribute to your vehicle’s performance.
