When you are looking for a new set of tires, the options can be overwhelming. Do you go with a smaller size or a bigger size? What brand should you choose? And what about the type of tire? Should you get all-season tires or performance tires? One of the most important decisions is deciding between 295 55r20 and 305 55r20 tires.
In this table, we will help you make that decision by discussing the pros and cons of each size.

The 295 55r20 tire size is a common choice for many vehicles. This size tire is meant for light trucks and SUVs. They offer a good balance of traction, comfort, and durability. The first number is the width of the tire in millimeters. In this example, it is 295 millimeters.
The second number is known as the aspect ratio. This measures how tall the sidewall is about the width.
The aspect ratio is 55, which means that the tire’s sidewall height is 55 percent of its width. The third letter on the sidewall is the tire construction. The most common construction is “R,” which stands for radial. The fourth and fifth numbers are the wheel diameter in inches. In this case, it is 20 inches.
Tire Width
One of the main differences between 295 55r20 and 305 55r20 tires is width. The 295 is 20 millimeters narrower than the 305. In short, The width of the 295 55r20 is 295 millimeters, and the width of the 305 55r20 is 305 millimeters.
This may not seem like a big difference, but it can affect your vehicle’s performance. A wider tire will provide more stability and grip. A narrower tire will be lighter and offer better fuel economy.
Aspect Ratio
As we mentioned before, the aspect ratio is the second number on the sidewall. It measures how tall the sidewall is about the width of the tire. The higher the aspect ratio, the taller the sidewall.
The aspect ratio of the 295 55r20 is 55, and the aspect ratio of 305 55r20 is also 55. This means that the height of the tire is 55% of the width.
So, the Aspect Ratio of 295 55r20 is 55% which is 162.25 millimeters, and the Aspect Ratio of 305 55r20 is 55% which is 167.75 millimeters. The difference in aspect ratio between the about 5 millimeters. It’s important to note that the width and aspect ratio can affect the tire’s diameter.
Construction Type
Another thing to note is the construction type. The most common construction type is “R,” which is radial. Radial tires are the standard for many passenger vehicles. They are made with steel belts that run across the tread and provide good stability and durability. Both of the tire sizes have the same construction type. So, the 295 55r20 and 305 55r20 both have radial construction.
Rim Size
The last number on the sidewall is the rim diameter. This is the size of the wheel that the tire will fit on.
In this example, it is 20 inches. The difference between 295 55r20 and 305 55r20 is that the former has a 20-inch rim, and the latter has a 20-inch rim. In This aspect, there is no difference between them.
Circumference
One important thing to note is that the width and aspect ratio can affect the tire’s diameter. The diameter is the distance from one side of the tire to the other. It’s important because it determines how much ground contact the tire has.
The circumference is the distance around the outside of the tire. To calculate it, you need to know the diameter. The circumference of the 295 55r20 is 102.97 inches and the circumference of the 305 55r20 is 104.33 inches. As you can see, there is about a one-and-a-half-inch difference in circumference between the two sizes.
Revolutions Per Mile
The revolution per mile or RPM measures how often the tire goes around in one mile. To calculate it, you need to know the circumference of the tire.
The RPM of the 295 55r20 is 615, and the RPM of the 305 55r20 is 607. So, there are about eight fewer revolutions per mile with the 295 55r20.report this ad
Conclusion
Now that you know the basics of tire size, you can start to compare different sizes. Keep in mind that width, aspect ratio, and diameter can all affect the performance of your vehicle. The best way to decide which size is right for you is to consult with a professional.
They will be able to help you find the perfect tire for your needs. Thanks for reading! We hope this article was helpful. Please feel free to share it with your friends or family if you find it useful.
