What Does 285 75r17 tire Mean?
The 285 75r17 tire is a popular size for many vehicles. The “285” refers to the tire’s width in millimeters, while the “75” refers to the sidewall height. The “r” indicates that it is a radial tire, and the “17” refers to the diameter of the wheel in inches. They offer a good balance of traction and stability and can be used in off-road and on-road applications.
Tire Width
When comparing 285 75r17 and 295 70r17 tires, you will first notice that the 295 is slightly wider. This can provide some benefits in terms of traction, but it can also make the tire more susceptible to damage from road debris.
The width of the 295 70r17 is 295 millimeters, and the width of the 285 75r17 is 285 millimeters. The difference in width between the two tires is 10 millimeters. The 295 70r17 is also known as a “wide base” tire, while the 285 75r17 is considered a “narrow base” tire.
The wide base tires were designed for vehicles with wider track widths, such as trucks and SUVs. They offer improved stability and handling but can also be more difficult to find in specific sizes.
Aspect Ratio
The aspect ratio is the second number in the tire size and refers to the sidewall height. The higher the number, the taller the sidewall and the smaller the contact patch. The 285 75r17 has a sidewall height of 75, which is taller than the 70 of the 295 70r17.
So, the Aspect Ratio of 295 70r17 is 70% which is 206.5, and the Aspect Ratio of 285 75r17 is 75% which is 213.75mm. The difference in aspect ratio between the two tires is about 7 millimeters. The taller sidewall of the 285 75r17 provides a smoother ride. Still, it also makes the tire more susceptible to damage from road debris.
Construction Type
The “r” in the tire size indicates a radial tire. This is the most common type of tire construction and offers a good balance of traction, stability, and durability.
The other type of tire construction is known as “bias ply,” which is not as expected. Bias-ply tires are typically found on older vehicles or off-road vehicles. They are less durable than radial tires, and they do.
Rim Size
The last number in the tire size is the diameter of the wheel in inches. The 285 75r17 has a wheel diameter of 17 inches, while the 295 70r17 has a wheel diameter of 17 inches. The difference in diameter between the two tires is 0 inches. Both tires can fit on a 17-inch wheel, but the 285 75r17 will have a slightly taller profile.
Circumference
The circumference of a tire is the distance around the outside of the tire. The 285 75r17 has a circumference of about 106.28 inches, while the 295 70r17 has a circumference of about 104.49 inches. The difference in circumference between the two tires is approximately 1 inch.
Revolutions Per Mile
Another significant difference between 285 75r17 and 295 70r17 tires is the revolutions per minute (RPM). The higher the RPM, the faster the tire will rotate. The 285 75r17 has an RPM of about 596.15, while the 295 70r17 has an RPM of about 606.38. This difference may seem like little, but it can increase over time.
Our observation
The main difference between 285 75r17 and 295 70r17 tires is the width. The 285 75r17 is a narrower tire, while the 295 70r17 is a wider tire. The tire’s width can affect traction, stability, and durability.
