Let's get to know what the aspect ratio of car tires is

Drivemate, have you ever heard about the aspect ratio of car tires? Each type of car tire has its own specifications. Tire specifications are adjusted to the car specifications. For example, tires for a large MPV type car will certainly be different from those for a sedan type car. Well, the aspect ratio of car tires is the easiest way to identify tire specifications.

The aspect ratio of car tires is usually placed on the sidewall or sidewall of the tire. To better understand the aspect ratio of car tires, let's look at the following explanation.

Get to know the aspect ratio of car tires

Each tire is made with special specifications that make it different from one another. At first glance, the differences between car tire specifications are not very clear. For this reason, most tire manufacturers will include information called the aspect ratio of the car tire.

The aspect ratio of a car tire is basically a measurement between the height of the sidewall of the tire and the cross-sectional width of the tire. So, what information can be known from this aspect ratio? Keep reading this review to find out the answer!

Large aspect ratio versus small aspect ratio

As mentioned in the previous point, the aspect ratio of car tires is a measure of the height of the sidewall and the width of the tire. From these measurements, two types of aspect ratios are known, namely large ratios and small ratios.

A large aspect ratio means that the sidewall size of the tire is also large. Meanwhile, a small aspect ratio value indicates that the tire sidewall tends to be low. The smaller the aspect ratio of a car's tires indicates better cornering ability. However, lower side walls can also make driving feel less smooth compared to higher walls.

On the other hand, a tire with a large aspect ratio means it has a high sidewall. However, this type of tire is not good for cornering. Even so, tires with high sidewalls are more comfortable to drive, especially on winding roads.

Reading the aspect ratio of car tires

The aspect ratio of car tires is usually listed on the cross-section of the tire. However, sometimes, there are also manufacturers who only list the height and width of the tire and consumers have to calculate the tire aspect ratio themselves.

You can find information about the aspect ratio of car tires just to the right of the usage description. The first three numbers before the slash indicate the cross-sectional width of the tire in millimeters (mm). Meanwhile, the two numbers after the slash are the aspect ratio of the car tires.

Calculating the aspect ratio of car tires

To make it easier to understand how to calculate the aspect ratio for car tires, see the following example:

For example, the ENASAVE EC300+ tire from Dunlop is an OEM tire for the Toyota All New KIJANG INNOVA. On these tires, information is listed as 205/65 R16 95H. From there, it can be seen that the aspect ratio for ENASAVE EC300+ is 65% of the total height of the tire sidewall. Meanwhile, the number 205 indicates the width of the tire tread, which is 205 mm or 20.5 cm. To find out the height of the tire, you can follow the following formula:

Tire sidewall height = Sidewall width x Car tire aspect ratio

In the example of the ENASAVE EC300+ tire above, it can be seen that the sidewall height is as follows:

Tire sidewall height = 205 x 65/100

Tire sidewall height = 133.35

So, the sidewall height of the ENASAVE EC300+ tire is 133.35 mm or 13.335 cm which is 65% of the 205 mm cross-sectional width of the car tire.

 

Information such as the aspect ratio of car tires is very important for drivers. By knowing this information, you will have no trouble when you have to look for new tires. You will not experience the problem of difficulty finding the aspect ratio of your car tires when using OEM (original equipment manufacturer) tires from Dunlop.

All OEM tires from Dunlop have clear tire code information, including aspect ratio. Clear information on the tires can make it easier for you when you want to change tires.
