## What’s The Difference Between 215/65r16 and 225/60r16 Tire?

By now you’ve learned the basics of using two tires interchangeably, now let’s see implementing the theory in a real example. Below, we have compared 215/65r16 and 225/60r16 tires in terms of width, aspect ratio, construction materials, and rim diameter.

### Width

If you measure from one sidewall to the other sidewall of a tire, you will get the width. It is expressed in millimeters. You can instantly learn the Width of a tire just by looking at the tire size index.

The first three digits of a tire size index indicate the Width of that tire. As you can see, the first three digits of 215/65r16 are 215. It means the width of that tire is 215 millimeters.

Likewise, the three-digit number of 225/60r16 is 225. It means the Width of that tire is 225 millimeters. So the difference in the Width is 225 – 215 = 10 millimeters.

Now, if you switch to the tire size which is 0 millimeters more or less in Width, it shouldn’t be a problem.

But you cannot switch tire size depending on Width only. You must consider the Sidewall Height as well. The Sidewall Height depends on Width and Aspect Ratio.

### Aspect Ratio

As you can see, there’s a difference between the Aspect Ratio of the two tire sizes. The aspect ratio of 215/65r16 is 65, whereas the aspect ratio of 225/60r16 is 60.

So to check the interchangeability of these tires, our sole concern is to analyze how the differences in the aspect ratio impact the other measurements. Let’s start with the simple question first: what is the Aspect Ratio? And its relation with other measurements.

Aspect Ratio is the ratio of the sidewall from wheel to tread and the width. This measurement is usually represented in a percentage.

In our example, 215/65r16 Tire size has a width of 215 with an aspect ratio of 65%. So the sidewall height will be 215 x 0.65 or 5.5 inches or 139.75 mm. You can get the number by simply putting the value on the equation.

**Equation:** Height of a Sidewall = Aspect Ratio of Tire x Width.

On the other hand, the Sidewall Height of 225/60r16 is 5.3 inches. Though the Aspect Ratio of the two tire sizes is different, they have almost a similar sidewall height.

Hence 215/65 is thinner but interchangeable with 225/60.

### Construction Type

The tire size index informs you about the Construction Type of a tire. It is expressed by a letter in the tire size index.

Both 215/65r16 and 225/60r16 have the same letter ‘R’. So, both the tires have Radial Construction in terms of construction type.

Such tires have a sophisticated construction with square footprints on the top. The Radial tires are ideal for driving on-road.

They are resistant to heat and water. They are next-gen tires and can provide excellent fuel efficiency.

Another famous construction type is Bias Ply. They are also known as Cross-ply. It is expressed by the letter ‘B’ in a tire size index. This type is great for driving off-road.

### Rim Diameter

To know which tire size fits your vehicle, you must know the wheel rim size of your vehicle as well as the Rim Diameter of a tire.

For instance, if your vehicle has a 16-inch wheel rim, you can use the tire which has a 16-inch Rim Diameter.

By looking at a tire size index, you can learn instantly the Rim Diameter of a tire. The last two digits of a tire size index indicate the Rim Diameter. It is measured in inches.

As you can see, the Rim Diameter of 215/65r16 is 16 inches. Similarly, the Rim Diameter of 225/60r16 is 16 inches.

It means that if your vehicle has a 16-inch wheel rim, you can use both tire sizes. But make sure to use the same size tires for all the wheels.

## Can You Interchange Between 215/65r16 vs 225/60r16 Tire?

**Yes, you can indeed interchange these tires. However, we have several mixed opinions regarding this. **

Although it has decent compatibility, some factors are above the 3 percent compatibility margin. As such, while you can use these tires, we would recommend you think twice before using them.
