Overall Diameter

The 305 70r17 size tire has an overall diameter of 33.9 inches or 860 mm. This is the measurement from one end of the tire to the other. It is important to know the overall diameter because it will determine if the tire will fit on your vehicle. If the overall diameter is too big or too small, it will not fit on your vehicle.

Section Width

The section width of a 305 70r17 tire is 12.0 inches or 305 mm. This is the width of the tire from one side to the other. The section width is important because it will determine how much contact the tire has with the ground. A wider tire will have more contact with the ground, providing better traction.

Circumference

The circumference of a 305 70r17 tire is 106. 4 inches or 2700.4 mm. This is the distance around the tire. The circumference is important because it will determine how far the tire will travel in one revolution. A longer circumference will mean that the tire will travel further in one revolution.

Revolutions Per Mile

The revolutions per mile (RPM) of a 305 70r17 tire is 595. This is the number of times the tire will go around in one mile. The RPM is important because it will determine how fast the tire will travel. A higher RPM will mean that the tire will travel faster.

Sidewall Height

The sidewall height of a 305 70r17 tire is 8.4 inches or 214 mm. This is the tire’s height from the edge of the rim to the top of the tire. The sidewall height is important because it will determine how much suspension travel you have. A taller sidewall will mean that you have more suspension travel.

Wheel Size

The wheel size of a 305 70r17 tire is 17 inches. This is the diameter of the wheel that the tire will fit on. The wheel size is important because it will determine the size of the tire. A larger wheel will mean that you need a larger tire.

Construction Type

The construction type of a 305 70r17 tire is radial. This means that the layers of the tire are perpendicular to the centerline of the tire. Radial tires are the most common tire type used on most passenger vehicles.

305 70R17 is the same size as 33.9x12R17. To sum up, the overall diameter is 33.9 inches, the section width is 12.00 inches, and the circumference is 106.41 inches. The sidewall height is approximately 8.4 inches, give or take a few millimeters.

The wheel size is 17 inches in diameter. And finally, the construction type is radial. I hope this blog post has answered all of your questions about the 305 70r17 tire size. If you have any other questions, feel free to leave a comment below!report this ad

NOTE: Verification of the vehicle’s rim size must be completed if the vehicle model is available in one or more O.E. rim width options or if the vehicle is currently equipped with non-original equipment rims.
Original equipment sizes are based on the best information currently available to us. Variations based on options or changes by the manufacturer may change the original equipment size on your vehicle. Please verify the size listed matches the tire size listed on your vehicle (usually found in the door jamb) or in the Owner’s Manual. Replacement of tires with a speed rating less than the original equipment tires may reduce performance and handling.
NOTE: We make every effort to ensure that the following search results are up-to-date and accurately presented. Some variables, including vehicle modifications, “Plus Size” fitments or search menu selection errors, may result in incorrect data.
If you have any questions regarding the correct product for your vehicle, please contact a Customer Service Advisor at your local store who will assist you in selecting the correct size.
NOTE: Winter driving presents special challenges for vehicle mobility. The use of winter tires while improving traction performance in snow and ice — requires special care with regard to acceleration, braking, cornering and speed. It is important to drive with care, not only on snow and ice, but on dry and wet roads as well.
In winter driving conditions, vehicle control — and safe operation — under braking and cornering is especially dependent upon the rear tires. For this reason, winter tires are best applied to all wheel positions.
Some vehicles have specific recommendations regarding winter tires and their usage; always check and follow the vehicle tire placard and/or the vehicle owner’s manual.

• Winter tires are best applied to all wheel positions.
• If winter tires are applied to the front axle of any vehicle, they must also be installed on the rear. Do not apply winter tires to only the front axle — this applies to all passenger cars, SUVs and light trucks, including front wheel drive, 4X4 and all-wheel drive vehicles.
• If winter tires are applied to the rear axle of any vehicle, it is recommended (but not required) that they be installed on the front axle.
• All winter tires applied should be the same speed rating. It is generally acceptable to apply winter tires with a lower speed rating than the Original Equipment/All Season tires for use in winter conditions; however, speed should be reduced accordingly. Vehicles should never exceed the “top speed” of the lowest speed-rated tire on the vehicle. Otherwise, tire failure could result.
• Winter tires operated in summer conditions may wear rapidly.
• Studded tires, where legally allowed, follow the same recommendations above.

Comparison of 305/70 R17 and 305/70 R16 tire sizes.

In the table above you can see a detailed comparison of the difference in dimensions, parameters and performance between a 305/70 R17 tire and a 305/70 R16 tire. The results of the calculations are also presented in the form of visual models (infographics), on which the tire with a size of 305/70 R17 is on top, and with a size of 305/70 R16, respectively, at the bottom. The visualization was generated in two projections: lateral (left) and frontal (right). The online calculator compares tires according to the following characteristics: diameter, width, circumference, profile height, revolutions per km, ground clearance change. In addition, a potential deviation between the actual speed and the speed displayed on the speedometer is calculated, which can occur if the difference between tires 305/70 R17 and 305/70 R16 is significant.
