What Does 265 75R16 Mean?

The numbers on the tire’s title refer to the Tire Size Index. Each of the numbers on the index indicates specific characteristics of the tire. 

Let’s have a look at each of the numbers and see what they mean. 

The first number on the tire size index (265) indicates the tire’s width in millimeters. That means the 265 75R16 tire has 265 millimeters in width. 

The double digit number after that (75) reveals the aspect ratio of the tire which is measured by dividing the tire height by its width and multiplying it by 100. 

Aspect ratio= (Height/Width) x 100

Aspect ratio of the tire also indicates the tire sidewall height (also known as profile).

Note that, the sidewall height is proportional to the aspect ratio. Therefore, the higher the aspect ratio, the taller the sidewall. For the 265 75R16 tires, the sidewall is 75% as high as its width. 

After the first two numbers on the tire size index, the alphabet affirms the tire type. Here, R means that this tire is a Radial construction type — which is considered to be the standard in the industry.

Radial construction tires, such as the 265 75R16 & 275 70R16, are made out of a mix of polyester, steel, and fabric. These tires are coated with rubber and they provide more grip, mileage, and durability. 

The last number (16) confirms the rim diameter in inches. The 265 75R16 tire is suitable for a 16 inches rim.

What Does 265 70R16 Tire Mean?

Now, you should have an idea of what a 265 70R16 tire means. 

From the title, you can grasp that the tire has a 265 width. It has a 70 aspect ratio — which means the tire’s height is 70% as high as its width.

Moreover, you can be sure that the tire has a durable construction and it can offer satisfactory mileage and grip.

Lastly, from the title. you understand that the tire will fit a 16 inches rim. 

As you can see from the specifications, the only difference between the 265 70R16 and 265 75R16 tires is the difference in aspect ratio. The latter tire has a 5% higher aspect ratio compared to the former. 

The aspect ratio largely affects the steering quality. A lower aspect ratio (70) reduces the time to transmit the steering input from the wheel to the tread. It also causes a more rigid ride. 

This little difference in aspect ratio changes the circumference, sidewall, and revs per mile.
