Overall Diameter
The first thing you’ll notice is that the 265 70r17 size has a slightly larger overall diameter than the 245 70r17. The overall diameter of the 265 70r17 tire size is 31.61 inches, and 30.5 inches is the diameter of the tire size.
This difference is about 1.1 inches, or about 28mm. That might not sound like much, but it can make a big difference in how your vehicle handles. A larger diameter tire will provide more stability, and a smaller diameter tire will be more agile.
Section Width
The section width is the width of the tire from sidewall to sidewall. The 265 70r17 has a section width of about 10.43 inches, while the 245 70r17 has a section width of about 9.65 inches.
A wider tire will provide better traction but also create more drag on the vehicle. A narrower tire will have less rolling resistance, but it might not provide as much traction.
Circumference
The circumference of the 265 70r17 is about 99.29 inches, and the 245 70r17 has a circumference of approximately 95.83 inches. A larger circumference tire will cover more ground per revolution, which can be helpful if you’re doing a lot of highway driving. A smaller circumference tire will provide better acceleration since it has less rotational mass.
Revolutions Per Mile
The number of revolutions per mile (RPM) is how many times the tire will go around in a mile. The 265 70r17 has an RPM of about 638, while the 245 70r17 has an RPM of about 661.
A higher RPM tire will cover more ground in a given amount of time, but it will also create more noise and wear out faster. A lower RPM tire will cover less ground per revolution, but it will last longer and be quieter.
Sidewall Height
The sidewall height is the distance from the edge of the tire to the rim. The 265 70r17 has a sidewall height of about 7.30 inches, while the 245 70r17 has a sidewall height of about 6.75 inches.
The taller the sidewall, the more cushioning the tire will have. This can make for a smoother ride, but it can also make the vehicle less responsive. A shorter sidewall will provide less cushioning, but it will make the vehicle more responsive.
Wheel Size
The wheel size is the diameter of the wheel that the tire is mounted on. The 265 70r17 can be mounted on a 17-inch wheel, while the 245 70r17 can be mounted on a 17-inch wheel.
A larger wheel will provide more stability but also create more drag on the vehicle. A smaller wheel will have less rolling resistance but might not provide as much traction.
Construction Type
The 265 70r17 can be made with radial construction, while the 245 70r17 can only be made with radial construction. Radial tires are made with the cords running perpendicular to the direction of travel. This makes for a smoother ride, but it can also make the tire less responsive.
Our Observation
The main difference between 245 70r17 and 265 70r17 tire size is in the section width. The section width of the 265 70r17 tire size is 0.79 inches or about 8.2% wider than the 245 70r17 tire size.
When it comes to tires, wider is usually better because it provides more traction. However, wider tires also create more drag on the vehicle. If you’re looking for the best tire size for your needs, it’s essential to strike a balance between traction and drag.
Conclusion
The 245 70r17 and 265 70r17 tire sizes have pros and cons. Choosing the right tire size for your needs is important to get the best performance from your vehicle. If you’re not sure which tire size is right for you, it’s always a good idea to consult with a professional. They’ll be able to help you choose the right tire size for your vehicle and driving habits. We hope this article was helpful.
