245/65r17 tire size in inches Analysis
Along with the 245/65r17 tire size table mentioned above, here I am detailing the definition of the different features of this tire. Understanding the definition of every feature is important for car owners. It helps to make a proper decision while buying new tires.
Sidewall Height
One of the most important factors to consider when choosing a tire is its sidewall height. There is a distance between the edge of the tire and the rim of the tire that is known as sidewall height. Tires with a sidewall height of 245 65r17 have a 6.27-inch sidewall.
Overall tire Diameter
There’s an overall diameter of 29.54 inches on the 245 65r17 tires. Higher sidewalls make your car look sporty. This can result in a better handling experience for your vehicle as well as a more comfortable driving experience.
The Section width
A 245/65R17 tire measures 9.6 inches wide or 245 mm at its widest point, excluding decorations, protective ribs, or raised letters. Tread width, cross-section width, and section width are also terms that refer to the tire width.
It is good practice to measure tire width after properly inflating and mounting the tire on its industry-specific measuring rim without putting any load on it.
Circumference
The circumference of a tire serves as a measure of how far it travels during one revolution. A pair of 245 65r17 tires measures 92.80 inches in circumference. It affects a vehicle’s speedometer, odometer, and gear ratio.
Revolutions Per Mile
Approximately 424 mph or 682 kph is the maximum speed of the 245 65r17 tires. When a tire is measured in RPM, it represents how many times it has to roll to cover one mile.
Therefore, it takes 424 rolls of 245 65r17 tire size to cover one mile. In general, a vehicle that runs at a higher RPM will run at a faster speed.
Radius
In accordance with the 245 65r17 tire specification, the radius is 14.77 inches. Using the sidewall height and the radius of the rims, you can determine the actual radius of a tire.
If you understand the radius of a tire, you will be able to obtain spare parts for it more easily.
Rim diameter
In making a comparison between these two types of tires, it is also essential to consider the diameter of the rim or wheel. It is 17 inches in diameter for the rims of the 245 65r17 tires.
As a result, a tire of this size will fit on a wheel with a diameter of 17 inches. A larger rim diameter will increase the safety of your vehicle while driving.
Rim Width Range
For a given tire size, the rim width range refers to the acceptable range of rim widths. Tire manufacturers specify a recommended rim width range for each size to ensure optimal tire performance, safety, and durability.
In the case of the 245/65r17 tire size, the recommended rim width ranges from 7 inches to 8.5 inches. This means the tire can fit on rims within this width range, but rims outside this range can compromise the tire’s safety and performance.
Construction Type
Radial tires have a construction type of 245 65r17. A 245 65r17 tire has R as part of its name, which indicates that the layers run radially. The typical wheel size for passenger vehicles is R.
In general, tires with this type of construction are the most common. You will experience a smoother ride as a result. Further, it minimizes the build-up of heat.
Aspect ratio
After the slash and before the letter R in the sequence, you can find the aspect ratio, which is the height of the tire’s sidewall. The aspect ratio of the 245/65r17 tire is 65.
According to this formula, the tire’s height equals 65% of its width, and thus the larger the aspect ratio, the wider the tire’s sidewalls.

UTQG
In the tire industry, the term “UTQG” refers to a uniform tire quality grading system. The system facilitates the comparison and rating of tires on the basis of tread wear, traction, and temperature.
A tire’s traction is how much grip it has. In the temperature rating, you can see how well the tires disperse heat. There are three ratings: superior (A), good (B), and average (C) for traction and temperature.
For example, the 245/65r17 tire size with UTQG 600 A B represents the tire’s comparative wear compared to the rated 100. So, the tire rated at 600 would last six times as long as the government’s mandated tire.
