What Does 35×12 50r17 Tire Mean?
The 35×12 50r17 tire size is also known for its stability and traction, making it a good choice for those who want to take their vehicle off-road. The first number, 35, means that the diameter of this size is 35 inches.
The second number is 12.50, indicating that this tire’s section width is 12.5 inches. The letter on the tire size R means it is a radial tire. The last number, 17, stands for the diameter of the wheel in inches that this tire can be used on.
Tire Diameter
One of the most important aspects of any tire size is the diameter. The 315 70r17 tires have a diameter of 34.36 inches, while the 35×12 50r17 tires have a diameter of 35 inches. The difference in the diameter is 0.67 inches or 1.9%. This difference in diameter is significant because it can affect your vehicle’s overall speed and handling.
In general, the larger the diameter of the tire, the higher the top speed that your vehicle will be able to achieve. This is because the larger tire will have a longer circumference, which means it can cover more ground in a single revolution.
Section Width
The tire’s section width is the second number in the size designation. The 315 70r17 tires have a section width of 12.4 inches, while the 35×12 50r17 tires have a width of 12.50 inches.
This difference in section width is significant because it can affect the grip and traction of your tires. The more comprehensive the tire, the more grip and traction it will have. This is because there is more surface area in contact with the ground.
However, it is important to note that too much grip and traction can be bad. If your tires are too wide, they may cause your vehicle to feel unstable and can make it more difficult to control.
Circumference
The circumference of a tire is the distance around the outside of the tire. The 315 70r17 tires have a circumference of 107.95 inches, while the 35×12 50r17 tires have a circumference of 110.04 inches.
This difference in circumference is important because it can affect your vehicle’s overall speed and handling. In general, the larger the circumference of the tire, the higher the top speed that your vehicle will be able to achieve.
Revolutions Per Mile
The revolutions per mile (RPM) is the number of times your tires will go around in a single mile. The 315 70r17 tires have an RPM of 586, while the 35×12 50r17 tires have an RPM of 575. This difference in RPM is important because it can affect your vehicle’s fuel economy.
In general, the lower the RPM, the better the fuel economy. It takes less energy to move a tire with a lower RPM. The difference in fuel economy between these two sizes is not significant. Still, it is something to keep in mind if you want to save gas money.
Sidewall Height
A tire’s sidewall height is the distance from the edge of the rim to the top of the tread. The 315 70r17 tires have a sidewall height of 8.68 inches, while the 35×12 50r17 tires have a sidewall height of 9.01 inches. The difference in the sidewall height is 0.33 inches or 3.8%.
Wheel Size
Another important aspect of any tire size is the wheel size. Both tire sizes can fit 17 inches rim. So, the wheel size is not a factor when deciding between these two sizes.
Construction Type
The construction type of a tire is how the layers of the tire are put together. The 315 70r17 tires have a radial construction, while the 35×12 50r17 tires are also radial. The construction type of a tire is not a significant factor in deciding between these two sizes. Still, it is something to keep in mind.
They are characterized by the way the cords in the carcass are arranged. The cords in a radial tire run perpendicular to the direction of travel. This gives radial tires a higher strength and durability than other tires.
Our Observation
After looking at all the differences between these two tire sizes, the 35×12 50r17 tires are the better option. They have a more comprehensive section width, giving you more grip and traction. They also have a larger circumference which will improve the speed and handling of your vehicle.
And while the difference in fuel economy is insignificant, the 35×12 50r17 tires will still get slightly better gas mileage than the 315 70r17 tires. So, if you are looking for the best performance, the 35×12 50r17 tires are the way to go.
Conclusion
The main difference between 315 70r17 and 35×12 50r17 tire sizes is the section width, circumference, and RPM. The 315 has a smaller section width, circumference, and RPM.
The 35×12 50r17 has a wider section width, giving you more grip and traction. Thanks for reading! We hope this was helpful. If you have any questions, please feel free to leave a comment below.
