If you are a car enthusiast, you have probably heard the term “Stretched Tire”. However, many of you may not know what exactly it means.

This article will therefore explain the effects and purpose of a Stretched Tire. If you are considering dressing up your car with Stretched Tire, please refer to this article.

What Is A Stretched Tire?

A Stretched Tire is a tire that is narrower in width relative to the size of the wheel. It is called a stretched tire because the tire is pulled outward by the wheel being thicker than the tire.

Many users prefer stretched tires for dress-up purposes because the pulled shoulder of the tire gives the wheel more impact. They also have characteristics similar to low-flat tires and have the effect of sharpening the handling.

The procedure for installing a stretched tire is the same as that for a regular tire, but the assembly process is more difficult. Therefore, if you wish to install a stretched tire, we recommend that you consult an expert.

What Are The Advantages Of Using A Stretched Tire?

The biggest advantage of a Stretched Tire is the dress-up effect, which, as mentioned above, makes the wheels look more distinguished. Another benefit is that they are less likely to interfere with fenders. This is because the shoulder of the tire pulls inward when the vehicle height is lowered.

If you are aiming for a “tree-lined” look, commonly referred to as a “straight line” between the fender and the side of the wheel, a stretched tire would be an option.

In addition, low-flat tires can be substituted inexpensively with stretched tires because they have similar characteristics to “low-flat tires” that improve driving performance. They will appear stiffer than regular tires and have sharper handling.

What Are The Disadvantages Of A Stretched Tire?

The disadvantage of a stretched tire is the management of air pressure. Basically, it is adjusted higher, but if it is not managed properly, the tire may come off or burst. Since the tires are forced to be worn thinner, it is necessary to adjust the air pressure frequently.

In addition, if excessively stretched tires that exceed the manufacturer’s standards are installed, performance may not be maximized. Stability and grip may be reduced and you may experience discomfort while driving.

What Is The Proper Air Pressure For A Stretched Tire?

Most manufacturers recommend approximately 3 kg/cm2. Considering thermal expansion, a range of about 2.7 to 3.3 kg/cm2 is safe. It is important to keep within approximately 10% of the standard value.

Especially when driving on highways, air pressure above the standard value is not acceptable because of the tendency to thermal expansion.

Tire pressure can be adjusted at a gas station. After changing to pulled tires, check the air pressure frequently. You can also measure air pressure at home, but be aware that inexpensive air pressure gauges have a large margin of error.

However, this is not to say that inexpensive air pressure gauges are useless. The important thing is to know the margin of error. First, have the tires inflated at a tire store, etc., and then measure the air pressure with your own air pressure gauge.

For example, if the pressure should be 3 kg/cm2 but it reads 2.8 kg/cm2, the error is 0.2 kg/cm2. In this case, +0.2 kg/cm2 from the display should be used as the correct air pressure.

How Far Is It Safe To Pull Tires?

Pulling beyond the “compatible rim width” of the tire is dangerous. Installing a tire that exceeds the range of compatible rim widths will cause the tire to pull excessively, creating a gap between the wheel and the tire.

Also, if the range of the compatible rim width is exceeded, the bead of the tire may not be raised.

Even if there is no air leakage when the tire is stationary, air may leak out (rim drop) when the tire kinks, such as when the steering wheel is turned too far.


In this article, we have explained the pulled tire. The contents can be summarized as follows.

  • A stretched tire is a tire that is narrower than the width of the wheel.
  • When installing a stretched tire, make sure that the width of the tire does not exceed the width of the rim to which it fits.

In addition to the dress-up effect, a stretched tire has advantages in terms of driving and function. However, pulling beyond the necessary rim width can be dangerous.

If you are considering a pulled tire, please take these risks into consideration.
