285 75R16 Vs 285 70R16 Tire – Discussion on Differences
Now, let us discuss all the major differences in detail so that you can understand the topic well. Here goes the discussion: –
Section Width
The section width of a tire refers to the width of the tire measured in millimeters from sidewall to sidewall when mounted on a rim and properly inflated.
One unique aspect of section width is that it can vary depending on the rim width on which the tire is mounted.
The cross-section width for the 285 70r16 tires is 11.22 inches. On the contrary, the cross-section width for the 285 70r16 tires is also the same. So, in terms of the section width, there is no difference between the two tires.
Sidewall Height
The sidewall height of a tire, also known as the aspect ratio, is the ratio of the height of the tire’s sidewall to its section width.
For example, if a tire has a section width of 205 millimeters and an aspect ratio of 60, its sidewall height would be 60% of 205 millimeters or 123 millimeters.
The sidewall height for the 285 70r16 tires is 7.85 inches. Whereas, the sidewall height for the 285 70r16 tires is 8.42 inches. The difference between the two tires in this regard is 0.56 inches or 7.1%.
Revs Per Mile
Revs per mile, also known as revolutions per mile (RPM), is a measurement of how many times a tire rotates on its axis per mile of travel. One unique aspect of revs per mile is its impact on vehicle performance and fuel efficiency.
The revs per mile for the 285 70r16 tires is 636 km. On the contrary, the revs per mile for the 285 75r16 tires is 614 km. The difference between the two tires in this regard is 22 km or 3.4%.
Overall Diameter
The overall diameter of a tire is a crucial measurement that refers to the distance between the outer edges of a tire when it’s fully inflated and mounted on a rim. One unique aspect of overall diameter is its effect on a vehicle’s speedometer accuracy.
A tire with a larger overall diameter will travel a greater distance with each revolution than a tire with a smaller overall diameter, even if both tires are rotating at the same speed.
The overall diameter for the 285 70r16 tires is 31.71 inches. On the contrary, the overall diameter for the 285 75r16 tires is 32.83 inches. The difference between the two tires in this respect is 1.12 inches or 3.5%.
Circumference
The circumference of a tire is the distance around the outer edge of the tire, also known as its perimeter. One unique aspect of tire circumference is its impact on a vehicle’s gearing and transmission.
The circumference of a tire can determine the number of rotations needed to cover a specific distance, which affects the vehicle’s effective gear ratio.
The circumference for the 285 70r16 tires is 99.62 inches. Whereas, the circumference for the 285 75r16 tires is 103.14 inches. The difference between the two tires in this regard is 3.53 inches or 3.5%.
Radius
The radius of a tire is the distance from the center of the wheel to the outer edge of the tire. One unique aspect of tire radius is its impact on steering and cornering.
The radius for the 285 70r16 tires is 15.85 inches. On the contrary, the radius for the 285 75r16 tires is 16.42 inches. The difference between the two tires in this regard is 0.57 inches.
Rim Diameter
The rim diameter of a tire refers to the diameter of the wheel rim on which the tire is mounted. One unique aspect of rim diameter is its impact on tire selection.
Different tire sizes are designed to fit specific rim diameters, so the rim diameter can limit the range of tire options available for a given vehicle.
The rim diameter for both the tires 285 70r16 and 285 75r16 is 16 inches. This means that both tires are designed to fit 16 inches rim.
Rim Width Range
The rim width range of a tire refers to the range of acceptable wheel widths on which the tire can be mounted. One unique aspect of rim width range is its impact on tire profile.
The tire’s section width, aspect ratio, and overall diameter are all affected by the width of the wheel on which the tire is mounted.
The rim width range for the 285 70r16 tires is 7-9 inches. On the contrary, the rim width range for the 285 75r16 tires is 7.50-9 inches. The difference between the two tires in this regard is 0.50 inches.
Typical Weight
The weight of tires can vary widely depending on their size, construction, and intended use. One unique aspect of tire weight is its impact on vehicle fuel efficiency.
Heavier tires can increase rolling resistance, which can reduce fuel economy and increase emissions. The exact opposite is true for lighter tires.
The typical weight for the 285 70r16 tires is 50 lbs. Whereas, the typical weight for the 285 75r16 tires is 58.6 lbs. The difference between the two tires in this regard is 8.6 inches.
Tread Depth
The tread depth of a tire is a critical measurement that affects the tire’s performance, safety, and longevity. One unique aspect of tread depth is its impact on traction and handling.
The tread depth for the 285 70r16 tires is 11/32 inches. Whereas, the tread depth for the 285 75r16 tires is 15/32 inches. The difference between the two tires in this regard is 4 inches.
Tire Type
Radial tires are a type of tire construction that features the reinforcement cords running perpendicular to the direction of travel, or “radially” from the center of the tire. This is in contrast to bias-ply tires, which have cords running diagonally across the tire.
One unique aspect of radial tires is their superior handling and ride comfort. The radial tire design allows for a more flexible sidewall, which can provide a smoother and more comfortable ride. It is really great to see that both the tires 285 70r16 and 285 75r16 have radial tire construction types.
285 75R16 Vs 285 70R16 Tire: What Do Letter & Number Mean?
285: This number indicates the width of the tire in millimeters. This means that both tires have the same tire width of 285 millimeters.
70 & 75: After the width, comes the aspect ratio of the tire represented by these two numbers. It usually refers to the height of the sidewall compared to the width. The aspect ratio of the 285 70r16 tires is 70% of its width. Whereas, the aspect ratio of the 285 75r16 tires is 75% of its width.
R: This letter R stands for the radial construction type of the tires. Both tires 285 70r16 and 285 75r16 have radial tire construction types.
16: The number 16 followed by the letter R usually represents the rim size on which the tire can easily fit. Both tires 285 70r16 and 285 75r16 can be used on the same wheel size which is 16 inches each.

Frequently Asked Questions
People around the world ask many important questions regarding the various types of tires available in the market. Some of the frequently asked questions are given below: –
Will the Two Tire Sizes Have the Same Overall Diameter?
No, the overall diameter of the two tire sizes will be slightly different. The overall diameter of a tire is calculated by adding the height of the sidewall (twice) to the diameter of the wheel.
Because the sidewall height is different between the two sizes, the overall diameter will also be different. The 285 75r16 tires have a slightly larger overall diameter than the 285 70r16 tire.
Can I Replace a Tire in One Size with a Tire in the Other Size?
It’s generally not recommended to mix tire sizes on a vehicle, as it can affect handling and safety. If you need to replace a tire, it’s best to stick with the same size that’s already on the vehicle or consult with a tire professional to determine the best replacement size if the original size is not available.
Which Tire Size Is Better for Off-Roading 285 75R16 or 285 70R16?
Both tire sizes can work well for off-roading, but the 285 75r16 may be slightly better for certain types of terrain, such as deep mud or loose sand, because of its taller sidewall. The taller sidewall allows the tire to flex more, which can help it maintain traction in these types of conditions.
Will the Two Tire Sizes Affect My Gas Mileage?
Yes, the two tire sizes may affect your gas mileage to some extent. Generally speaking, a larger tire will cause your engine to work slightly harder to turn the wheels, which can lead to slightly lower gas mileage. However, the effect on your gas mileage will likely be small and may not even be noticeable in some cases.
