Dimensions in Inches

  1. Overall Diameter: The overall diameter of the 235/75r15 tire is 733 mm, which is equivalent to 28.9 inches. This measurement refers to the height of the tire when inflated and mounted on a wheel.
  2. Tread Width: The tread width of this tire size is 235 mm, or approximately 9.3 inches. This measurement describes the width of the tire’s contact patch with the ground, which can impact traction and handling.
  3. Rim Diameter: The rim diameter for the 235/75r15 tire size is 381 mm, or 15 inches. This measurement indicates the diameter of the wheel that the tire is designed to fit.
  4. Sidewall Height: The sidewall height of this tire size is 176 mm, or roughly 6.9 inches. This measurement represents the distance from the tire’s bead (where it seals against the wheel) to the edge of the tread.
  5. Circumference: The circumference of the 235/75r15 tire size is 2301.6 mm, or about 90.7 inches. This measurement refers to the distance around the outer edge of the tire when inflated and mounted on a wheel.

Relevant Specifications

  1. Revolutions per Mile: The 235/75r15 tire size has approximately 696 revolutions per mile. This metric is essential for determining speedometer and odometer accuracy and can impact fuel efficiency and overall vehicle performance.
  2. Tire Construction: The “r” in the tire size (235/75r15) indicates that it is a radial tire. Radial tires have layers of fabric (usually polyester, steel, or a combination) running radially across the tire from bead to bead, with additional layers of steel belts underneath the tread for added strength and durability. Radial tires generally provide better traction, handling, and longer wear life compared to bias-ply tires.
  3. Load Carrying Capacity: The load carrying capacity of a tire is determined by its load index, which is not directly provided in the tire size (235/75r15). However, you can find the load index on the tire’s sidewall, usually next to the tire size information. This index indicates the maximum weight the tire can safely support when properly inflated.
  4. Speed Rating: Like the load index, the speed rating is not directly provided in the tire size but can be found on the tire’s sidewall. The speed rating is a letter that indicates the maximum speed the tire can safely maintain for a sustained period. For example, a tire with a speed rating of “S” can safely maintain speeds up to 112 mph.

How Wide Are 235/75r15 Tires?

A 235/75R15 tire has a width of 235 millimeters. To convert this measurement to inches, you can divide the millimeters by 25.4 (since there are 25.4 millimeters in an inch).

235 millimeters ÷ 25.4 = 9.25 inches

So, a 235/75R15 tire is approximately 9.25 inches wide.

What Size Wheels Fit 235/75r15 Tires?

To determine the appropriate wheel size for a 235/75R15 tire, you need to consider both the width and diameter of the wheel. For this tire, the wheel diameter must be 15 inches. As for the wheel width, it’s essential to choose a wheel that can safely accommodate the tire’s width.

For a 235mm wide tire, a wheel width between 6 and 8 inches is generally recommended. However, it’s always best to consult the tire manufacturer’s recommendations or a professional tire dealer to ensure the correct wheel size for your specific tire and vehicle.

How Big Is A 235/75r15 Tire?

To find the tire’s overall height, we need to add the sidewall height twice (for both the top and bottom sidewalls) to the wheel diameter:

Overall Diameter = (2 x Sidewall Height) + Wheel Diameter

Overall Diameter = (2 x 6.94 inches) + 15 inches = 13.88 inches + 15 inches = 28.88 inches

So, a 235/75R15 tire has an approximate overall diameter of 28.88 inches (733.5 millimeters).
