What Does 255 75r17 Tire Mean?
The 255 in 255 75r17 tire means that the tire’s width is 255 millimeters. The 75 is the aspect ratio, which tells you how tall the tire is. In this case, the height of the tire is 75% of its width. The R stands for radial, and 17 is the diameter of the wheel in inches, and the letter R indicates that the tires are radial.
Tire Width
The width of the 255 is 255 millimeters, and the width of the 285 is 285 millimeters. The difference in width is 30 millimeters, which may not seem like much, but it can make a big difference in the way your vehicle handles. Wider tires provide more grip on the road and are better able to handle turns at high speeds.
They also tend to wear down more evenly, which can save you money in the long run. However, wider tires are not always the best choice. They can make your ride less comfortable and cause your vehicle to use more fuel. If you live in an area with a lot of snow or mud, narrower tires may be a better choice because they will provide better traction.
Aspect Ratio
As we mentioned before, the aspect ratio is the height of the tire. In this case, the height of the 255 is 75% of its width, which is 191.25 millimeters and the height of the 285 is 75% of its width, which is 213.75 millimeters. The height difference is not as significant as the difference in width. However, it can still affect how your vehicle handles.
Construction Type
The final difference between these two sizes is the construction type. Both 255 75r17 and 285 75r17 Tires are radial tires. Radial tires are the most common type of tire on the market and are known for their long-lasting tread life. They are also more resistant to heat build-up, which can cause premature tire failure.
Rim Size
When choosing between these two sizes, the last thing to consider is the rim size. The 255 75r17 tires are designed to fit a 17-inch wheel, and the 285 75r17 tires are designed to provide a 17-inch wheel. If you have a 17-inch wheel on your vehicle, you can choose either size. However, if you need to check your car manual to confirm the rim size.
Circumference
One other thing to consider when choosing between 255 75r17 and 285 75r17 tires is the circumference. The circumference is the distance around the outside of the tire. The circumference of the 255 is 100.72 inches and the circumference of the 285 is 106.28 inches.
The difference in circumference is around 6 inches. This can be important to consider because a larger circumference will result in higher rolling resistance. This means that your vehicle will use more fuel to maintain the same speed.
Revolutions Per Mile
Revolutions Per Mile (RPM) is the number of times your tires will rotate in one mile. The higher the RPM, the more fuel your vehicle will use. The 255 75r17 has an RPM of 629, and the 285 75r17 has an RPM of 596. This means that the 255 will go through slightly more revolutions in one mile than the 285.
Our Observation
The main difference between 255 75r17 and 285 75r17 Tire is the width, aspect ratio, and circumference. The 255 has a broader width which can provide more grip on the road but may cause your vehicle to use more fuel. This can affect the way your vehicle handles.
Conclusion
If you are looking for a tire that will provide more grip on the road and handle high speeds, the 255 may be better. If you are looking for a tire that is more resistant to heat build-up and has a longer tread life, the 285 may be a better choice.
Ultimately, the decision between these two sizes depends on your driving needs and preferences. Whichever size you choose, make sure to get the correct rim size for your vehicle.
