746.86 RPM or 464.08 KMRevolutions Per Mile difference 10.49(6.52) 1.4 (km)757.35 RPM or 470.59 KM

For starters, both the circumference and diameter have the same percentage difference. This is at -1.4 percent, which is below the 3 percent margin. As such, both tires are compatible in terms of this factor.

However, the case isn’t the same for the width and sidewall length. The percentage difference between these is the width and sidewall heights are around 4.7 and -3.4 percent respectively. 

Finally, when it comes to the revolutions per mile, the percentage difference between the two tires is 1.4 percent which is in the safe zone.

How to read the tire sizes 215/65r16 and 225/60r16?

There are four parts to the tire size 215/65r16, and each part bears a certain meaning. Before you decide to interchange or replace the Tire, you must learn about them. Here is the explanation of each part of the tire size 215/65r16.

  • 215 means the width of the tires in millimeters
  • 65 shows the percentage of height to the width or the Aspect Ratio
  • R Indicates Radial Construction
  • 16 Indicates the Diameter of the Rim

Doing the Same for Tire Sizes 225/60r16.

  • 225 means the width of the tires in millimeters
  • 60 shows the percentage of height to the width or the Aspect Ratio
  • R indicates Radial Construction
  • 16 indicates the Diameter of the Rim

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.

What you must consider Before Interchange or Replace Tire? 

There are important things to consider before replacing or swiping the Tires. You cannot simply replace the 215/65r16 tire with the 225/60r16 tire that is in a different shape.

For example, if the aspect ratio of the existing tire is 40%, replacing it with a tire that has an aspect ratio of  45% might not be a good option.

Doing so will have various consequences on the car’s overall performance, such as variations in top speed and speedometer.

However, you can switch Tires to a certain extent, such as minor changes in the diameter or the sidewall. However, this can only be done in compliance with the manufacturers’ recommendations.

Anyway, when replacing the Tire, the simple guideline to follow is that the current tire’s size, load index, and speed rating should all match with the replacement Tire.

Load Index and Speed Index of a Tire 215/65r16 and 225/60r16

The load index refers to the maximum load-bearing capacity, whereas the speed index refers to the Tire’s maximum allowable speed at a full load. These are very crucial stats to know before you decide to interchange tires.

Index information can be found on the sidewall after the Tire size number. It is a combination of numbers and letters that bear a particular meaning. 

Here is an example of how the index information is usually written on the sidewall: 215/65r16 90A. The 90A stands for load and speed index, with 90 indicating a maximum load-bearing capacity of 600 kg, whereas ‘A’ denotes an allowed speed of up to 170 km/h.

Check the load and speed index. They must be as close as possible to fit precisely. These values change depending on the vehicle’s weight and wheel size. Here is a table that shows various load and speed indexes, so you get the idea.

Load IndexKgSpeed IndexSpeed Limit
65290QUp to 160 Km/h
66300RUp to 170 Km/h
67307SUp to 180 Km/h
68315TUp to 190 Km/h
69325HUp to 210 Km/h

Size of the Tire 

The size of the Tire is another vital piece of information to know to exchange the tires properly. The large number on the sidewall shows the tire size.

For example, the mark 215/65r16 on the sidewall represents the size of the Tire. You can also find it in the user manual, on the sidewall, and in other places such as inside the fuel flap or glove compartment.

What Size Tires Is 215/65r16 in Inches?

215/65r16 tires have a 27″ diameter, 8.5″ section width, and 16″ wheel diameter.

The circumference is 84.8″ and they make 747 revolutions per mile. The Sidewall Height of this Tire is 5.5 inches.

What Size Tires Is 225/60r16 in Inches?

225/60r16 tires have a diameter of 26.6″, a section width of 8.9″, and a wheel diameter of 16″. 

The circumference is 83.6″ and they have 758 revolutions per mile. The Sidewall Height of this Tire is 5.3 inches.

Conclusion

To conclude things, there are several preparations that you must make sure to do before deciding on the final part of the tires that you will be buying for interchange purposes.

First of all, make sure to do your research well. You can choose from plenty of choices, so make sure to find the exact size requirement of your vehicle’s wheel. 

Then look for a professional and consult them about your decision. Only after getting the green light from them should you venture on the purchase.
