Dimensions Breakdown
The tire size 245/70r17 is equivalent to 30.6×9.6R17 in inches. The tire size 245/70r17 can be broken down into several components, each of which provides valuable information about the tire’s size, construction, and performance. Here’s a breakdown of what each component means:
- 245 – This number indicates the tire’s width in millimeters from sidewall to sidewall when mounted and inflated to its recommended pressure. In this case, the tire’s width is 245 millimeters.
- 70 – This number represents the aspect ratio, which is the ratio of the tire’s height to its width. It indicates the height of the tire’s sidewall as a percentage of its width. In this case, the height of the tire’s sidewall is 70% of its width.
- R – This letter indicates that the tire is of radial construction. Radial tires have a ply cord that runs perpendicular to the tire’s direction of travel, providing better stability and handling.
- 17 – This number indicates the diameter of the wheel or rim the tire is designed to fit. In this case, the tire is designed to fit a 17-inch wheel or rim.
Putting it all together, the tire size 245/70r17 means that the tire is 245 millimeters wide, has a sidewall height that is 70% of its width, is of radial construction, and is designed to fit a 17-inch wheel or rim.
Tire Height
The overall diameter, also known as tire height, is a crucial dimension to consider when selecting a tire size. The overall diameter of the tire size 245/70r17 is 776 mm or 30.6 inches. This measurement is crucial as it affects the speedometer reading and the vehicle’s overall performance.
Tread Width
The tread width is the width of the tire’s contact patch that comes in contact with the road. The tread width of the tire size 245/70r17 is 245 mm or 9.6 inches. This measurement is critical as it determines the tire’s ability to handle the vehicle’s weight and provide stability during driving.
Rim Diameter
The rim diameter is the wheel size that the tire will fit onto. The rim diameter for the tire size 245/70r17 is 431.8 mm or 17 inches. Ensuring the tire size matches the rim diameter is essential to avoid any fitting issues.
Sidewall Height
The sidewall height is the distance from the rim to the outside edge of the tire’s tread. The sidewall height for the tire size 245/70r17 is 172 mm or 6.8 inches. This measurement is important as it affects the tire’s ability to absorb shocks and impacts from the road.
Circumference
The circumference of a tire is the distance it covers in one revolution. The circumference for the tire size 245/70r17 is 2436.6 mm or 96.1 inches. This measurement is important as it affects the speedometer reading and it also affects the tire’s rolling resistance.
Revolutions Per Mile
The revolutions per mile, also known as the RPM, is the number of times the tire rotates in one mile. The RPM for the tire size 245/70r17 is 659. This measurement is important as it affects the fuel efficiency and the tire’s overall lifespan.
Tire Construction
The construction of a tire is an important factor to consider when selecting a tire size. The tire size 245/70r17 is a radial tire, indicated by the letter “r” in the size designation.
Radial tires have a ply cord that runs perpendicular to the tire’s direction of travel, providing better stability and handling. The tire also has a load index of 110, indicating its ability to carry a maximum load of 2337 pounds.
How Tall Are 245/70r17 Tires?
The overall diameter, or tire height, of 245/70r17 tires is approximately 30.6 inches or 776mm. This measurement includes the tire tread, sidewall, and rim diameter. The sidewall height of a 245/70r17 tire is approximately 172mm or 6.8 inches, the distance from the rim to the outside edge of the tire’s tread.
Can I Use 245/70r17 Instead Of 245/65r17?
Yes, you can use 245/70R17 tires instead of 245/65R17 tires, but there are some important factors to consider before making the switch.
The main difference between the two sizes is the height of the tire. The 245/70R17 tire is approximately 1 inch taller than the 245/65R17 tire. This change in height can affect the speedometer reading, the gear ratios, and the ground clearance of your vehicle.
Additionally, the 70-series tire is wider than the 65-series tire. This can affect the handling and stability of your vehicle, especially at higher speeds. You may also need to check for compatibility with your vehicle’s wheel wells and suspension components to ensure enough clearance for the wider tire.
It is also important to consider the load capacity and speed rating of the tires. Make sure that the tires you choose are rated for the weight of your vehicle and the speeds at which you typically drive.
Our Observation
After analyzing the dimensions and specifications of the tire size 245/70r17, we can conclude that it is versatile and suitable for various vehicles. The tire’s 9.6-inch tread width provides good stability and handling, while the 6.8-inch sidewall height offers good shock absorption.
The tire’s 17-inch rim diameter is a popular size, ensuring that it fits most vehicles requiring this tire size. The overall diameter of 30.6 inches is a standard size consistent with the original equipment tire size, making it an excellent choice for those who want to maintain their vehicle’s original performance.
