# What Does 123/120R Mean on a Tire

When you’re shopping for tires, you may see a number of different tire sizes listed. For example, one size might be listed as “123/120R.” But what does that actually mean?

Here’s a quick guide to understanding tire sizing so you can make sure you’re getting the right tires for your car.
The first number in a tire size (like “123”) is the width of the tire in millimeters. The second number (like “120”) is the height of the tire, known as the aspect ratio.

The final letter (like “R”) indicates the construction of the tire. In this case, “R” means radial construction.

When you’re shopping for tires, you might see a designation like 123/120R. So, what does this mean? Here’s a quick explanation:

The first number (123) is the width of the tire in millimeters. The second number (120) is the aspect ratio, which is the height of the tire sidewall as a percentage of the width. So, in this case, the sidewall height would be 120mm.

The R at the end indicates that it’s a radial tire.
Now that you know what those numbers mean, you can start shopping for tires with confidence!

## What Does 120S Mean on Tires?

When shopping for tires, you may have noticed the “120s” designation and wondered what it meant. 120s refer to the tire’s load index and speed rating. The load index is a numerical code that corresponds to the maximum weight that the tire can support when properly inflated.

The speed rating tells you the maximum speed at which the tire can be driven safely.
The combination of these two numbers provides important information about a tire’s capabilities. For example, a tire with a load index of 120 and a speed rating of “S” can safely carry 2,271 lbs at 112 mph.

Knowing this information can help you choose the right tires for your vehicle and driving needs.

## What Load Range is 123?

There is no definitive answer to this question as it depends on a number of factors, such as the type of vehicle, the weight of the load, and the road conditions. However, a good rule of thumb is that a load range of 123 would be suitable for a light duty truck or SUV.

## What Does 125 R Mean on a Tire?

When you’re shopping for tires, you’ll often see a number like “125 R” on the sidewall of the tire. This number is called the tire’s service description, and it provides important information about the tire. Here’s a breakdown of what the numbers and letters in a typical service description mean:

The first number (125) is the width of the tire in millimeters. The second number (R) indicates that this is a radial tire. The last number (16) is the diameter of the wheel that this tire is designed to fit, in inches.

So, in this example, 125 R 16 means that the tire has a width of 125 mm and is a radial tire designed to fit a 16-inch wheel.

## What Do the 3 Numbers Mean for Tires?

The three numbers on a tire’s sidewall represent a combination of the width, height and diameter of the tire. The width is the first number listed and corresponds to the width of the tire in millimeters. The second number is the height, which represents the distance from the edge of the wheel rim to the top of the tread in millimeters.

The third number is the wheel’s diameter in inches.

## 114T Tire Meaning

If you see a 114T on a tire, it means that the load index is 114 and the speed rating is T. The load index is a number that corresponds to the maximum weight that the tire can support. The speed rating is a letter that corresponds to the maximum speed at which the tire can be driven.

## What Does 120Q Mean on a Tire

The 120Q on a tire stands for the load index and speed rating. The load index is how much weight the tire can carry. The speed rating is how fast the tire can go.

## What Does 110T Mean on a Tire

If you take a look at the sidewall of a tire, you’ll see a lot of different numbers and codes. These numbers and codes provide important information about the tire, including its size, load capacity, speed rating, and more. So, what does 110T mean on a tire?

110T is simply the load index number for that particular tire. The load index is used to identify how much weight a tire can support. In this case, 110T means that the tire can support up to 1,102 pounds (or 499 kilograms).

## Conclusion

The numbers and letters on the side of a tire can be daunting, but they actually provide valuable information about the tire. The numbers 123/120R refer to the width, aspect ratio, and rim size of the tire, respectively. The width is the distance from one sidewall to the other, while the aspect ratio is the height of the sidewall relative to the width.

The rim size is self-explanatory—it’s simply the diameter of the wheel that the tire is mounted on. With this information in mind, you can more easily select tires that will fit your car and meet your driving needs.
